Show HN: I use AI to send myself personalized weekly recaps from my saved links Sharing something that I’ve been working on: I made a save-later app for all my bookmarks. I save links throughout the week and, every Sunday morning, the app sends me a personalized recap with: -patterns and themes that connect my week to my broader interests -a nudge toward links I saved but never revisited -one reflective question to help me decide what else might be worth exploring I was inspired by older read-later apps like Instapaper. I wanted to make something minimalist, so it’s just a simple feed of your links (with tags and annotations linked to each link) and it is set up to ingest all kinds of content, not just text. I also did want it to be bloated as the full-fat AI stuff you see recently. So this is a simpler and more proactive take on the concept of a bookmarking app. Imagine if Pocket and Spotify Wrapped had a baby. I also personally enjoy using the chat to find links across subjects and sources with context, like “Show me the 5 links on travel i’ve returned to the most” or “all recipes with porcini mushrooms” or “show me everything on Topic X i’ve made the most notes on.” I’ve posted about this on HN before, always had great feedback. Happy to answer any questions. (I’m not technical, I'm a writer/ filmmaker.) https://tryeyeball.com/ July 31, 2025 at 04:38AM

Show HN: State of the Art Open-source alternative to ChatGPT Agents for browsing https://ift.tt/HgMKN5C

Show HN: State of the Art Open-source alternative to ChatGPT Agents for browsing Hey HN, We are Winston, Edward, and James, and we built Meka Agent, an open-source framework that lets vision-based LLMs execute tasks directly on a computer, just like a person would. Backstory: In the last few months, we've been building computer-use agents that have been used by various teams for QA testing, but realized that the underlying browsing frameworks aren't quite good enough yet. As such, we've been working on a browsing agent. We achieved 72.7% on WebArena compared to the previous state of the art set by OpenAI's new ChatGPT agent at 65.4%. You can read more about it here: https://ift.tt/cgDrHpW . Today, we are open sourcing Meka, our state of the art agent, to allow anyone to build their own powerful, vision-based agents from scratch. We provide the groundwork for the hard parts, so you don't have to: * True vision-based control: Meka doesn't just read HTML. It looks at the screen, identifies interactive elements, and decides where to click, type, and scroll. * Full computer access: It's not sandboxed in a browser. Meka operates with OS-level controls, allowing it to handle system dialogues, file uploads, and other interactions that browser-only automation tools can't. * Extensible by design: We've made it easy to plug in your own LLMs and computer providers. * State-of-the-art performance: 72.7% on WebArena Our goal is to enable developers to create repeatable, robust tasks on any computer just by prompting an agent, without worrying about the implementation details. We’d love to get your feedback on how this tool could fit into your automation workflows. Try it out and let us know what you think. You can find the repo on GitHub and get started quickly with our hosted platform, https://ift.tt/f69pnVH . Thanks, Winston, Edward, and James https://ift.tt/XF2dwTS July 30, 2025 at 07:41PM

Show HN: TanStack DB – Reactive DB with Differential Dataflow for TanStack Query Hi HN, Kyle, Sam and the TanStack team here. We’ve been working on TanStack DB, an embedded, reactive client database for TanStack Query, and are proud to announce today that with the 0.1 release that it's now in BETA! TanStack DB plugs into your existing TanStack Query useQuery calls and uses Differential Dataflow to incrementally recompute only what changed, so updates stay sub-millisecond even with 100k rows. You get live queries, optimistic updates with automatic rollback, and streaming joins — all in the client! TanStack DB works with REST, GraphQL, WebSockets, and shines with sync engines like ElectricSQL or Firebase, letting you load large, normalized collections once and stream real-time changes into the client without manual bookkeeping. It sits on top of queryClient so you can adopt it incrementally, one route at a time. - Intro post: https://ift.tt/e9v48NZ... - Local-first sync via Electric: https://ift.tt/2hvz8m5... - Web starter with TanStack Start: https://ift.tt/tm84noV... - Mobile starter with Expo: https://ift.tt/tm84noV... - Project website and docs: https://tanstack.com/db - GitHub repo: https://ift.tt/qyUgsKh Try it out and let us know what you think! https://ift.tt/8Z5PbFL July 29, 2025 at 11:18PM

Show HN: I built a deep email validation library in Kotlin https://ift.tt/6i7Rylq

Show HN: I built a deep email validation library in Kotlin Show HN: I built a deep email validation library to learn Kotlin Hey HN, I wanted a real-world project to properly learn Kotlin (coroutines, DSLs, etc.) and decided to tackle a problem I've found surprisingly underserved: comprehensive email validation. Most solutions stop at regex, but that doesn't prevent sign-ups from user@notarealdomain.com or disposable email services. So, I built a library that performs a series of deeper checks. I just tagged the v1.0.0 release because the API is now stable and I think it's ready for feedback from the community. It validates an email in layers: 1. Syntax: A robust check that's more reliable than a typical regex. 2. Domain Registrability: Checks the domain against the Public Suffix List to ensure it's on a real TLD. 3. MX Records: A DNS query to see if the domain is actually configured to receive email. 4. Disposable Services: Checks against a list of known temporary/throwaway email providers. 5. SMTP Connection (Optional): A live check to see if the mailbox actually exists. This is off by default since port 25 is often blocked, but can be enabled via a proxy. One of my main goals was to build something that would be useful on both the server and on a client like an Android app. This led to a couple of key design decisions: - It's built with coroutines for non-blocking, concurrent I/O. - It has a full offline mode. You can disable all network checks and run it using bundled datasets for things like syntax and disposable domain checks, which is great for providing instant, client-side feedback. The configuration is done through a simple Kotlin DSL. The project is MIT licensed. I'm posting this to get your thoughts on the approach, the architecture, or any Kotlin idioms I might have missed. How do you all typically handle this problem beyond regex? GitHub: https://ift.tt/ku46KW1 https://ift.tt/ku46KW1 July 29, 2025 at 11:40PM

Show HN: No Hype AI – get oriented in using LLM tools for software engineering https://ift.tt/P6F1vyZ

Show HN: No Hype AI – get oriented in using LLM tools for software engineering Hey HN! When I started looking into LLMs and agents for software development and introducing them at work, I quickly realised that a person new to the topic faces a real barrage: - all the hype (AGI, engineers getting replaced by AI etc.) - conflicting opinions in virtually every discussion—for every person saying they’ve 10x-ed their productivity, there is a comment decrying LLMs as an utter failure - a lot of jargon (MoE, MCP, RAG, distillation, quantisation etc. etc.) - a profusion of models, IDEs/IDE extensions, CLI agents, other tools etc. Sorting through all of this can be quite tricky for somebody coming in fresh! HN users have been discussing LLM tools for a long time of course, but many programmers I know still haven’t _really_ tried anything other than an LLM web UI and haven't been following the progress of tools much. So my goal for this project was to provide a balanced overview of the topic, point people to substantive resources on eg. context management and productivity effects, and cover the concerns and risks as well (from prompt injection to shady training data sourcing). I hope it's useful! https://nohypeai.dev July 28, 2025 at 01:09AM

Show HN: Flyde 1.0 – Like n8n, but in your codebase https://ift.tt/IDyO7e4

Show HN: Flyde 1.0 – Like n8n, but in your codebase Hi HN! I'm excited to share Flyde 1.0. A big update to the open-source visual programming tool I launched here in March of last year ( https://ift.tt/xbVTGnm ). Since Flyde’s launch, there's been a huge rise in demand for visual builders, especially for AI-heavy workflows. Visual-programming shines with async and concurrency-heavy logic, which describes most LLM chains perfectly. A few months ago, I tried to capitalize on this trend by launching a commercial version of Flyde called Flowcode ( https://ift.tt/snM2WlX ). It didn't go well. I learned the hard way that Flyde’s strength wasn't just about flexibility or performance compared to tools like n8n. The real value was always how Flyde fits inside your existing codebase . The launch also helped me understand that there's still a big gap: no tool really covers the full lifecycle, from rapid prototyping to deep integration, evaluation, and iteration inside your own projects. So, over the last few months, I worked hard to polish Flyde: - Cleaned up and simplified the nodes API - Made it possible to fork any node for maximum flexibility - Launched a new online playground for quick experimenting and sharing ( https://ift.tt/awIiUm8 ) - Created a new CLI tool to speed up development and setup - Fixed a ton of bugs - Simplified the UI/UX to make it smoother and less confusing There’s still a lot of missing stuff. Better templates, docs, and nodes, but I think it’s finally stable and useful enough to give it another shot. My plan is to first make sure that Flyde is usable and valuable as an OS project, and then try to provide additional value via “Flyde Studio” - a SaaS that will help non-engineers iterate on Flyde flows from a web-app. Changes become a PR in the host repo. I'd really love some honest feedback and hear whether Flyde resonates with an existing pain/problem. Check it out here: Playground: https://ift.tt/awIiUm8 GitHub: https://ift.tt/xyqd5fV Looking forward to hearing your thoughts! - Gabriel https://ift.tt/xyqd5fV July 27, 2025 at 11:46PM

Show HN: BlackMagic-JS – Automatic dark mode framework that just works https://ift.tt/52bQ8r3

Show HN: BlackMagic-JS – Automatic dark mode framework that just works I've been frustrated with dark mode implementations for years. Every solution requires hundreds of manual CSS rules, breaks accessibility, or looks terrible. So I built *BlackMagic-js* – the first framework that automatically converts any website to dark mode without breaking your design. ## The Problem Traditional dark mode is a nightmare: - Manual color definitions for every element - Broken contrast ratios (accessibility violations) - Lost brand colors and visual hierarchy - Weeks of CSS tweaking for basic functionality ## The Solution BlackMagic analyzes your existing colors and automatically: - *Calculates optimal dark alternatives* using color science - *Ensures WCAG 2.1 compliance* (4.5:1 contrast ratios) - *Preserves brand identity* while maintaining readability - *Works instantly* with zero configuration ## How It Works ```javascript // Traditional approach: 500+ lines of CSS .dark-mode .button { color: #fff; background: #333; } .dark-mode .text { color: #e0e0e0; } // ... endless manual definitions // BlackMagic approach: 3 lines const blackMagic = new BlackMagic(); blackMagic.toggle(); // Everything just works ``` *Technical magic:* - *HSL color space manipulation* (not RGB) for natural transitions - *Luminance calculations* with gamma correction for proper contrast - *DOM tree traversal* to detect inherited background colors - *Dual storage* (cookies + localStorage) for persistence ## Real Performance Tested across 50+ websites: - *98.7% WCAG compliance* automatically achieved - *<50ms* color calculation time - *8KB minified* with zero dependencies - *100% persistence* across browser sessions ## Quick Start ```bash npm install blackmagic-js ``` ```javascript import BlackMagic from 'blackmagic-js'; const darkMode = new BlackMagic({ backgroundColor: '#1a1a1a', factor: 0.4 // Adjustment intensity }); // Add to any button button.addEventListener('click', () => darkMode.toggle()); ``` CDN version: ```html ``` ## Why This Matters Dark mode is now *essential* for: - *70%+ of developers* prefer dark interfaces - *OLED battery savings* (up to 40% less power) - *Accessibility* for light-sensitive users - *Professional appearance* – users expect it BlackMagic makes implementation so trivial there's no excuse not to offer it. ## Advanced Features For power users: ```javascript const blackMagic = new BlackMagic({ themeClass: 'custom-dark', // Use CSS classes instead factor: 0.6, // More aggressive adjustment cookieDuration: 365, // Persist for 1 year autoSwitch: true // Apply saved theme on load }); ``` ## Browser Support - Chrome 60+, Firefox 60+, Safari 12+, Edge 79+ - Works with file:// URLs (great for testing) - Graceful fallback when localStorage unavailable ## Open Source & Testing - *GitHub*: https://ift.tt/GmWto6k - *NPM*: https://ift.tt/fD2GVnW - *MIT Licensed* with comprehensive examples - *Interactive demos* for every feature and edge case The repo includes 9 different test scenarios showing everything from basic usage to complex configurations. You can literally see it work on any website in seconds. https://ift.tt/GmWto6k July 25, 2025 at 11:59PM

It tries to schedule PTO around holidays so that you get the most consecutive time off while spending as few days as possible. You can set some constraints, customize the holidays and define mandatory vacation days (in case your company mandates them). If you try for 2025, you should see results for the rest of the year. If there are unscheduled days, it's because there isn't a particularly good period to take them off. (I should make this clearer in the site, to be honest).

Show HN: Compass CNC – Open-source handheld CNC router https://ift.tt/nyUmFaX

Show HN: Compass CNC – Open-source handheld CNC router Hey HN, I am Cam, and for the past two years I have been working on Compass, an open-source handheld CNC router that brings computer precision to woodworking while keeping the user directly involved in the process. The idea started as my senior design project at UC Berkeley, with the goal of making a more approachable CNC machine—standard CNC machines are expensive, bulky, and remove you from the tactile “maker” experience. Compass solves that by combining a handheld router with real-time robotic assistance. You move the router roughly along a design path, and Compass uses four optical flow sensors (like in computer mice) and a 3-axis motion system to auto-correct for precision cuts. What is different about Compass: - Open source: All plans, firmware, and CAD files are available on GitHub. - Affordable: The DIY build costs ~$600 in parts, and I am selling kits for <$800. - No external markers: The sensing technology allows for positioning without external markers, so no setup or consumables required. - Portable: Fits in a backpack and is not limited by a fixed work envelope. We recently completed our first beta program and have just launched V1 kits for pre-order. You can find more info and the launch video at the listed URL.

Show HN: Phind.design – Image editor & design tool powered by 4o / custom models https://ift.tt/2RDqxH3

Show HN: Phind.design – Image editor & design tool powered by 4o / custom models Hi HN, Today we’re launching phind.design ( https://phind.design ), an image editor and design tool that uses 4o and custom models to allow users to generate and edit designs for anything from logos and advertisements to creative website and app designs. 4o is great at producing a first version of an image, but is not capable of editing it without messing up other parts of it. We fix this by running Flux Kontext alongside 4o image gen in the chat, as well as by introducing a precision editor powered by custom models where a user indicates an area to modify and we guarantee that only that area will be modified. Our precision editor is state-of-the-art on image editing in our tests and allows inserting new additional images into the existing image. The latter allows users to insert a logo, product, or face into an image without messing up other parts of the image, and even fix logos and faces that were messed up by 4o. Text editing with the precision edit model is still a work in progress, and we will fix it with the next iteration of that model. We recommend using the chat for editing text for now. Example: Insert UT Austin logo into helicopter ad ( https://ift.tt/3d4pE9t ) We also always produce multiple variations for image generations and edits, as we think this variety is important for getting exactly what you asked for. Example: Paul Graham in startup heaven ( https://ift.tt/aUnHq8E ) One thing we’re excited about is adding more variation into AI-generated websites, as many website builders all use the same CSS libraries, so many websites end up looking the same. We hope to allow builders and creatives to make truly unique designs in 1/10th the time it currently takes with existing tools. Example: Make me a popeyes landing page where the eyes are actually popping out ( https://ift.tt/mY051rs ) Example: A train map with sandwich ingredients replacing subway stops. ( https://ift.tt/0oH9jiE ) As engineers who have been frustrated by the time commitment it takes to learn Figma or Photoshop, we hope that phind.design makes it incredibly easy to go from zero to one on your wildest creative ideas. The editor is far from perfect, particularly when it comes to text. We are working on it and have a new custom precision editing model on the way. In the meantime, we’re excited to hear your comments and feedback! https://phind.design July 22, 2025 at 11:14PM

Show HN: Lotas – Cursor for RStudio https://ift.tt/swEMK4R

Show HN: Lotas – Cursor for RStudio Hey HN! We’re Jorge and Will from Lotas ( https://www.lotas.ai/ ), and we’ve built an AI coding assistant into RStudio (think Cursor for RStudio). RStudio is used by about 2 million data scientists and academics, but they currently lack a coding assistant within their IDE. Developers in other environments benefit from tools like Cursor and Windsurf, but R users don’t have any equivalent tools to speed up their workflow. Since ~80% of R programmers prefer to use RStudio over other IDEs like VSCode to write R code, we figured a tool like this one could be quite useful. Both of us were PhD students at Harvard. Jorge was in the biophysics program and Will was in the biostatistics program where most people used RStudio every day. We saw how integrated code assistants were taking off in other IDEs, but we noticed that the RStudio integrations were still lagging far behind. Many R users were copying and pasting code from ChatGPT to build their workflows, and this was clearly slow and fragile. To bring the Cursor-like experience to RStudio users, we built Rao ( https://www.lotas.ai/ ): a fork of RStudio with an embedded AI assistant that is aware of the user’s local context (both files and variable environment), can read and write files, can run code or commands, and can interpret textual or visual output. It works with any of the file formats already in RStudio (R, notebooks including RMDs and QMDs, Python, Stan, etc.), allowing R programmers to iteratively perform entire data analyses inside their preferred IDE. Other AI data science tools are either (1) built on the web or in environments people don’t already use, (2) are completely focused on python notebooks, or (3) are weak package-based assistants with limited functionality. Rao is exactly like the RStudio IDE that millions of data scientists already use, but it incorporates a powerful AI assistant and works with all the standard file types. You can download Rao at https://ift.tt/0ZRzFyb , watch our demo on the homepage ( https://www.lotas.ai/ ), and work through some example use cases on our GitHub ( https://ift.tt/ZrYcoqM ). We have a one-week free trial (no card required) and provide 500 queries/month for $20/month after that. We’d love to hear feedback from the HN community to make Rao as useful as possible! You can reach us at founders@lotas.ai. P.S. We have zero data retention (ZDR) agreements with OpenAI and Anthropic, but we currently recommend users do not input sensitive or regulated data like PHI into Rao until we sign BAAs with both model providers.

It's essentially a locked-down environment where our team works that records their sessions, tracks every interaction, and prevents data from being copied or shared. It's been our internal source of truth for years. More recently, like many companies, we've been building more automation. And like everyone else, we've seen our automations fail on edge cases—a weirdly formatted invoice our parser can't read, a website layout change that breaks a scraper, etc. Our team would have to manually step in to fix these. We realized other developers must have this exact same problem, but without a 250-person team on standby. So we connected our old, battle-tested Hub to a new, modern front door: a Human-in-the-Loop (HITL) API. We're calling it browser-work.com. The idea is simple: when you hit a task that needs a human, you can send it to our team through the API. Here's how it works: - You POST a request to our endpoint. The payload contains the context for the task (like a URL) and a set of instructions for the human on what to do. - The task appears in the Hub, where one of our trained operators can claim it. - They perform the task exactly as instructed, all within the secure Hub environment. - When they're done, we send a webhook to your system. The return payload includes the task's output, any notes left by the human, and a detailed log of their actions (e.g., DOM elements they interacted with). For example, if your automation for paying a utility bill fails, you can pass the task to us. A person will log in, navigate the portal, make the payment, and return a confirmation number. The product is live and we're looking for people with interesting use cases. I'm Robert, the CIO. If this sounds useful to you, send me a brief email about your use case at robert@apmhelp.com and we can get you started right away. Happy to answer any questions here. https://ift.tt/Nfenmwh July 21, 2025 at 09:46PM

Show HN: Easyfaq.io – Free SEO-Optimized FAQ Page Generator (LLM-Friendly) https://ift.tt/7SbfaGs

Show HN: Easyfaq.io – Free SEO-Optimized FAQ Page Generator (LLM-Friendly) Hi HN I built EasyFAQ, a free tool that helps you generate and embed SEO-friendly FAQ pages. It’s aimed at making structured content easy to publish, especially for small sites, blogs, and landing pages. The generated FAQs include proper schema markup (JSON-LD), so they’re optimized for Google’s rich results and easier for large language models like ChatGPT to interpret accurately. I made this after noticing how much well-structured FAQs can improve site clarity and search visibility. The tool requires no login, and you can export or embed the generated FAQs directly. Would love feedback from the HN community — especially around UX, SEO usefulness, or other feature ideas. link: https://easyfaq.io Thanks! July 21, 2025 at 12:21AM

Show HN: The missing link of a bookstore's tech stack https://ift.tt/tbyhLPS

Show HN: The missing link of a bookstore's tech stack Hi HN! I built Bookhead because I used to work as a bookseller and I wasn't happy with the software options when I decided to sell my own collection online (with the hopes of one day growing so I can open my own brick & mortar). So I decided to make my own bookselling app...a classic hacker distraction. Bookhead has two main parts: 1. an inventory management app that allows a bookseller to list their books anywhere they want to sell books (like Squarespace, Biblio, eBay, Shopify (coming soon!), etc) 2. an e-commerce platform with a CMS for selling books and letting a store control their online brand I have a very exciting roadmap that I'm not ready to fully reveal, but it's all based on books. I'm building a sorta Zapier-like platform for independent booksellers. Everything is so fragmented and disconnected, which makes it hard for booksellers to do their work. I'm hoping to change that. I have a blog post that lays out my vision here: https://ift.tt/YhK4kbX The current iteration is like "data engineering as a service for books." A book is a powerful thing. I'm hoping to give a bookstore everything they need to sell books online. Inventory, e-commerce, marketing, etc. It's a crowded market but I've had fun making the bookselling app that I believe should exist. If you know any booksellers, please let them know about this! I'm onboarding my first customer right now and the biggest bottleneck is the other bookselling software providers, despite my intention to collaborate instead of compete. It's frustrating to wait for two weeks for a point of sale provider to setup an integration. It's almost like they don't care about their customers. Some providers even require ethernet cables for their software...still partying like it's 1999. Perfect for early-adopter booksellers frustrated with current tech who understand the power of automation. I'm currently looking for funding so I can focus on this full-time. My biggest problem right now is time (aka money) because I have to sell my time to make rent etc, and can't focus on this project like I need to. I've gotten good validation from booksellers and other technically savvy folks in the industry (I've heard from two different companies that they've considered building something like this), so I believe I have something valuable. I'm not interested in funding from somebody who doesn't share my love for books or doesn't support my mission: help people use technology to promote literature. I believe that literature is one of humanity’s most prized creations, and we can use technology as a tool to keep this gift alive. Please email me at sam@bookhead.net if you know of booksellers who might want to be an early adopter, or know of any funding opportunities that might be a good fit. https://bookhead.net/ July 21, 2025 at 12:19AM

Show HN: Transform passive YouTube watching into active learning https://ift.tt/EJYolz5

Show HN: Transform passive YouTube watching into active learning I've been self-learning from YouTube for years—everything from coding to design to business skills. But I kept hitting the same wall: YouTube learning has no structure. Your knowledge gets scattered across random playlists, you're passively consuming content without real retention, and when you're confused, there's nobody to ask. I built Notetube to fix this by layering organizational tools with AI to create a proper learning system: Organizational layer: Build structured collections by topic/course/skill, visualize your learning progress with dashboards, create and track your learning goals AI layer: Automatically generates detailed notes (3000+ words for 1 hour of content) and summaries, identifies key moments with timestamps, creates personalized quizzes for retention testing, and provides a chat interface for instant help when concepts aren't clear ...plus additional features like timestamped note-taking, but I'll keep this brief.

Show HN: I built library management app for those who outgrew spreadsheets I've been working on librari.io for the past several months and just launched the beta version. The Problem: I have 500+ books across multiple rooms in my house and was desperately looking for an app to manage them properly. Most library management apps are either too basic or designed for institutional libraries with rigid workflows that don't fit personal use. What I Built: - Multiple libraries: manage collections in different locations - Location tracking - remember exactly which shelf each book is on - Loan management - track books you've lent to friends - Custom fields & tags - store any additional book info the way YOU think about them - Reading progress tracking - dates, duration, personal ratings - Modern UI/UX - clean & actually enjoyable to use Current Status: - Beta version live - Working on improving the responsiveness of the app and addressing initial user feedback Would love feedback! Especially curious about: - What features would make YOU actually use a library management app? - UI/UX feedback always welcome - Any book collectors here who'd be interested in beta testing? Looking forward to your thoughts! Thank you in advance. https://www.librari.io/ July 19, 2025 at 12:58AM

Show HN: Tips for getting great Text2Cypher outputs from LLMs for Graph RAG For folks working on Graph RAG and trying to get LLMs to generate Cypher queries, I ran some experiments on the LDBC dataset and wrote a blog post about it (code is available in the link shown at the end of the post). I've been trying to answer a burning question of mine that I've had for a while now: when doing Text2Cypher, are LLMs better at interpreting graph schemas in JSON, XML or YAML? (Spoiler alert, the format barely matters, it's all to do with context engineering and retaining only the relevant parts of the graph schema in the prompt). Results on the latest LLMs are really good! The post also contains some other tips on graph schema design: I think we're in an age now where we need to design graph schema for both LLMs and humans. If you're working on Text2Cypher in any way, hope some of these ideas and experiments are useful! https://ift.tt/jJkObVm July 18, 2025 at 07:22PM

Show HN: I built a 2B-page search engine, independent of Google/Bing Hi HN, For the last 18 months, I've been working solo on building a completely independent search engine from scratch. Today, I'm opening it up for beta testing and would love to get your feedback. The project powers two public sites from the same 2-billion-page index: Searcha.Page: A session-aware search engine that uses a persistent browser key (not a cookie) for better context. Seek.Ninja: A 100% stateless, privacy-first version with no identifiers at all. The entire stack is self-hosted on a single ~$4k bare-metal EPYC server in my laundry room (no cloud, no VC funding). The search pipeline is a hybrid model, using a traditional lexical index for the heavy lifting and lightweight LLMs for specific tasks like query expansion and re-ranking. It's an experiment in capital efficiency and digital sovereignty—proving you don't need Big Tech APIs to compete. I’m looking for feedback on search result relevance, speed, and the clarity of the privacy models. Please try it out and let me know what you think.

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode https://ift.tt/2lEFZja

Show HN: A 'Choose Your Own Adventure' Written in Emacs Org Mode I authored and developed an interactive children's book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story. Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story. The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend. Ten Dollar Adventure: https://ift.tt/Nzs27hm Sample the Web Book (one complete storyline/adventure): https://ift.tt/6nDcS05 I couldn't muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.

Show HN: StartupList EU – A public directory of European startups I’m from Europe, and when I spent a summer at Stanford, I saw how different the startup ecosystem is in the US. Everything there feels connected. In Europe, it’s scattered. Hard to discover early-stage startups unless you’re in the right city or network. So I built StartupList EU, a public directory where anyone can list or browse European startups. The goals is to contribute to the EU startup ecosystem more accessible and transparent for founders, investors and operators. What it does: - Founders can submit their startup for free - Each profile includes data like team size, category, funding, revenues, location, founders and more - You can search by country, industry, name, team size, country and business model - It works across the whole EU, not just big hubs like Berlin or Paris Right now there are 34 startups listed. More are coming in daily. I’m working on better filters, API access, and a weekly newsletter. Would love your feedback: - What data would be most useful to you? - What would make this genuinely helpful for founders, investors, or researchers? - If you are from US, what's your take about EU startup ecosystem? https://ift.tt/VcHrgst July 15, 2025 at 01:54AM

Show HN: I made a JSFiddle-style playground to test and share prompts fast I built this out of frustration as I lead the development of AI features at Yola.com. Prompt testing should be simple and straightforward. All I wanted was a simple way to test prompts with variables and jinja2 templates across different models, ideally somthing I could open during a call, run few tests, and share results with my team. But every tool I tried hit me with a clunky UI, required login and API keys, or forced a lengthy setup process. And that's not all. Then came the pricing. The last quote I got for one of the tools on the market was $6,000/year for a team of 16 people in a use-it-or-loose-it way. For a tool we use maybe 2–3 times per sprint. That’s just ridiculous! IMO, it should be something more like JSFiddle. A simple prompt playground that does not require you to signup, does not require API keys, and let's experiment instantly, i.e. you just enter a browser URL and start working. Like JSFiddle has. And mainly, something that costs me nothing if I'm or my team is not using it. Eventually I gave up looking for solution and decided to build it by myself. Here it is: https://langfa.st Help me find what's wrong or missing or does not work from you perspctive. P.S. I did not put any limits or restrictions yet, so test it wisely.

Show HN: Transition – AI Triathlon Coach Hey HN, I’m Alex, a triathlete, dad, and software engineer. I’ve been building Transition — an app for triathletes that creates adaptive training plans based on your goals, schedule, and workout data (Garmin, Strava, etc). Most plans are static, which never really worked for me as a parent and someone with an unpredictable schedule. Transition adjusts every week using your actual workouts and progress, so the plan changes when you miss a session, set a new PR, or need to shift your priorities. I built this because nothing else was flexible enough for my life, and I’m curious if others have the same problem. It’s in beta and free to try. I’d love feedback from the HN crowd — especially around the training logic, onboarding, or any ways to make it more useful for real athletes.

Show HN: RULER – Easily apply RL to any agent https://ift.tt/Ch0iNza

Show HN: RULER – Easily apply RL to any agent Hey HN, Kyle here, one of the co-founders of OpenPipe. Reinforcement learning is one of the best techniques for making agents more reliable, and has been widely adopted by frontier labs. However, adoption in the outside community has been slow because it's so hard to implement. One of the biggest challenges when adapting RL to a new task is the need for a task-specific "reward function" (way of measuring success). This is often difficult to define, and requires either high-quality labeled data and/or significant domain expertise to generate. RULER is a drop-in reward function that works across different tasks without any of that complexity. It works by showing N trajectories to an LLM judge and asking it to rank them relative to each other. This sidesteps the calibration issues that plague most LLM-as-judge approaches. Combined with GRPO (which only cares about relative scores within groups), it just works (surprisingly well!). We have a full writeup on the blog, including results on 4 production tasks. On all 4 tasks, small Qwen 2.5 models trained with RULER+GRPO beat the best prompted frontier model, despite being significantly smaller and cheaper to run. Surprisingly, they even beat models trained with hand-crafted reward functions on 3/4 tasks! https://ift.tt/h2KpZOG Repo: https://ift.tt/zP3sB8K https://ift.tt/h2KpZOG July 11, 2025 at 11:17PM

Show HN: Open source alternative to Perplexity Comet https://ift.tt/qxizDLf

Show HN: Open source alternative to Perplexity Comet Hey HN, we're a YC startup building an open-source, privacy-first alternative to Perplexity Comet. No invite system unlike bunch of others – you can download it today from our website or GitHub: https://ift.tt/GvjWCtk --- Why bother building an alternative? We believe browsers will become the new operating systems, where we offload much bunch of our work to AI agents. But these agents will have access to all your sensitive data – emails, docs, on top of your browser history. Open-source, privacy-first alternatives need to exist. We're not a search or ad company, so no weird incentives. Your data stays on your machine. You can use local LLMs with Ollama . We also support BYOK (bring your own keys), so no $200/month plans. Another big difference vs Perplexity Comet: our agent runs locally in your browser (not on their server). You can actually watch it click around and do stuff, which is pretty cool! Short demo here: https://bit.ly/browserOS-demo --- How we built? We patch Chromium's C++ source code with our changes, so we have the same security as Google Chrome. We also have an auto-updater for security patches and regular updates. Working with Chromium's 15M lines of C++ has been another fun adventure that I'm writing a blog post on. Cursor/VSCode breaks at this scale, so we're back to using grep to find stuff and make changes. Claude code works surprisingly well too. Building the binary takes ~3 hours on our M4 Max MacBook. --- Next? We're just 2 people with a lot of work ahead (Firefox started with 3 hackers, history rhymes!). But we strongly believe that a privacy-first browser with local LLM support is more important than ever – since agents will have access to so much sensitive data. Looking forward to any and all comments! https://ift.tt/X6K5JaF July 10, 2025 at 11:03PM

Show HN: Activiews – A privacy-first fitness alternative for Apple users https://ift.tt/egchlnP

Show HN: Activiews – A privacy-first fitness alternative for Apple users Hi HN, I built Activiews as a fitness alternative for Apple users who want a simpler, more private, and more visual way to view their workouts, with a heavy focus on maps. The app reads from Apple Health and Watch data without requiring an account or sending anything to the cloud. I built it because I wanted a fitness app that: - Has no social network features - Does not store my data on their servers - Doesn't require an account or login - Stays lightweight and free of bloat - Is simple to use, with a focus on customizable workout visuals Core features: - Customizable workout maps and shareable cards - Flyover route animations - Calendar heatmap showing activity over time - Offline-first, data stays on device, no login/account needed - Dark/light themes, map styles, unit system, and accent color customizations - Reads data directly from Apple Watch - Localized in 13 languages - €0.99/month or €24.99 lifetime It’s built in Swift & SwiftUI using native APIs and focused on performance and privacy. I’d love your feedback, ideas, and comments. App Store: https://ift.tt/t1dO8RN Website: https://activiews.xyz Thanks! http://activiews.xyz/ July 11, 2025 at 12:28AM

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram https://ift.tt/y60H3rV

Show HN: Stravu – Editable, multi-player AI notebooks with text, tables, diagram Hi HN! I'm Karl one of the co-founders of Stravu. ( https://stravu.com ) Using AI for work 24x7, we realized that four things would make AI more useful for us and a lot of other power users and teams: Editable output: AI gives output that is half right and our only option was to either keep chatting laboriously or copy it to a Google Doc. We made Stravu so you can edit what the AI says in chat or in an attached notebook. Everything editable. Approve AI changes: When AI makes a change to some text, you can't tell what changes. We put Red/Green diffs that you can approve into Stravu. Unify text, tables, diagrams: We were jumping between tools to work with AI on text, tables, diagrams, etc.. Just because Microsoft did that 30 years ago, doesn't mean it makes sense now. We made Stravu so you can work with AI across text, tables, diagrams, (and 2x2s, formulas, more soon) and have them inform each other. Actual multi-player team collab with AI: We couldn't collaborate as a team in AI (even with the ChatGPT Teams plan). We wanted to be able to chat with AI together as a team or see the changes AI was making in the canvas/notebook together and edit together. So we made Stravu support multi-player collaboration in every aspect... chats, notebooks, text, tables, diagrams..etc. Some of the use cases of our current Beta customers include: scrum teams doing feature/customer/competitive research and feature definition, account teams building vertical/geo/account plans, consultants and investment teams working on market/company analysis. We are currently in beta and actively iterating based on user feedback. Please try it out at: https://stravu.com We highly value your feedback! July 9, 2025 at 07:47PM

Driving Muni’s Comeback Together: May Marked Highest Ridership Recovery Month
By Glennis Markison

You're helping us drive Muni’s strong recovery. Several routes now see more riders than they did pre-pandemic. In May, the 22 Fillmore saw 127% ridership recovery. Our teams have been working hard behind the scenes to make our transit system fast, frequent and reliable. We’re thrilled to see the results: more and more people choosing Muni. May marked our highest ridership recovery month since the pandemic began. And the data shows even more milestones – a comeback you drove just as much as we did. Weekend ridership reached 97% of 2019 levels – our highest weekend numbers since the pandemic...

Show HN: OpenAPI mocks that don't suck – realistic test data, quick setup https://ift.tt/nXtOxQI

Show HN: OpenAPI mocks that don't suck – realistic test data, quick setup Hi HN! I'm Ankit, the founder of Beeceptor, a request mocking and intercepting tool. This time, I built something new to address a pain I’ve personally felt (and heard from dozens of QA, frontend, and platform teams): making OpenAPI specs actually useful during development. API contracts just sit around as docs often. What if you could 'activate' them, instantly have a realistic, hosted mock server-with contract validation, smart test data, and early usage? So I made _Mockaroo for OpenAPI_, but with brains. It spins up a hosted mock server from your spec in one click. It: - Generates sensible context-aware, test data using FakerJS (e.g., age returns realistic numbers, not 10000) - Validates incoming requests against your contract definition and returns detailed, actionable error messages. - Supports JSON, binary, CRUD style API responses. - Gives a HOSTed API server URL, that's ready in a few seconds. - Helps frontend teams start testing before the backend is ready - Gives QAs a place to play, verify and run performance tests. - Enables the best developer experience, requiring no account setup and a working mock API server for experiments, and API cost savings. No local setup, no writing custom mock rules, no fuss. Just activate your OpenAPI spec, and your API starts “working” in seconds. Besides, Beeceptor shows live request logs, where responses can be overridden. Quick demo: https://www.youtube.com/watch?v=2vUD_B3aw5I --- Would love your thoughts, feedback, or use cases I haven’t thought of yet. Happy to share more technical details if there's interest. Thanks for reading! https://ift.tt/qS76dY0 July 9, 2025 at 01:00AM

Show HN: OffChess – 100k+ Offline, Ad-Free Chess Puzzles App https://ift.tt/Kwo5NsY

Show HN: OffChess – 100k+ Offline, Ad-Free Chess Puzzles App Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction. So I built OffChess. OffChess is an iPhone/Android app that contains over 100,000 chess puzzles, fully offline and completely ad-free. You can solve puzzles by category (Mate in 1/2/3/4/5, tactics like pins/forks/skewers, or openings like Sicilian/French, etc). You gain or lose points based on how you perform, so there's a light rating system to keep things engaging. No accounts, no tracking, no monthly subscriptions, no internet required. Just pure, old-school tactical chess training, wherever you are. You can check out the iPhone/iPad app at https://ift.tt/G1glBQK... or the Android app at https://ift.tt/GOSUBEF Would love feedback, bug reports, or suggestions. Thanks! https://offchess.com July 8, 2025 at 02:27PM

Show HN: Life_link, an app to send emergency alerts from anywhere https://ift.tt/ZWYfihk

Show HN: Life_link, an app to send emergency alerts from anywhere 2-factor authentication terrorizes me. Many years ago, I was at a friend's house and decided to quickly pop downstairs to buy something. When trying to re-enter the building, the main gate had locked. And since my phone, keys, and any spare cash were all left upstairs, I was stuck outside. Thankfully, Google, at the time, allowed users to send SMSes (SMSs?) through the Hangouts app, which I did after logging into my account from an internet cafe. (Back then people weren’t constantly connected to Facebook, etc.) Since that day I feared being locked out of my accounts by 2FA, simply because my phone (and my access codes) weren't with me. And while it's true that today people are always connected to messaging apps, I wouldn't be able to reach any of them without me being able to log into mine. That’s why I built life_link, an app that allows my loved ones to reach me, wherever they are, without having to care about 2FA or even needing to log in. To do so, they simply need to reach the app on a secret (short) URL. I've since expanded life_link by creating a "generator" app that can produce a pre-configured, single-file application, ready to be deployed on any static site hosting service and decided to open-source it for other people who might find it useful. You can find the life_link project and learn more about it here: https://ift.tt/dUgqQhP July 8, 2025 at 02:29AM

Show HN: Simple wrapper for Chrome's built-in local LLM (Gemini Nano) https://ift.tt/aVL6u8P

Show HN: Simple wrapper for Chrome's built-in local LLM (Gemini Nano) Chrome now includes a native on-device LLM (Gemini Nano) starting in version 138. I've been building with it since it was in origin trials, it's powerful but the official Prompt API is still a bit awkward: - Enforces sessions even for basic usage - Requires user-triggered downloads - Lacks type safety or structured error handling So I open-sourced a small TypeScript wrapper I originally built for other projects to smooth over the rough edges: github: https://ift.tt/i1GBgtZ npm: https://ift.tt/RpvFwUm - Stateless prompt() method inspired by Anthropic's SDK - Built-in error handling and Result-based .Safe.* variants with neverthrow - Token usage checks - Simple initialization that provides a helper to trigger downloads (must be triggered by user action) It’s intentionally minimal for hacking and prototyping. If you need fine-grained control (e.g. streaming, memory control), use the native API directly: https://ift.tt/hLVzSHl Would love to hear what people build with it or any feedback! https://ift.tt/i1GBgtZ July 6, 2025 at 11:24PM

Show HN: SteadyText: Deterministic LLMs: Same input → same output, every time Hey HN! After spending way too many nights debugging flaky AI tests, I built SteadyText. It's a simple python library for deterministic llm generations and embeddings. We use it in production for: - Testing our AI features (zero flakes in 3 months) - CLI tools that need consistent outputs - Reproducible documentation examples It's not for creative tasks - this is specifically for when you need AI to be boring and predictable. Think of it as the opposite of ChatGPT. The coolest part? It includes a Postgres extension. You can now do: SELECT steadytext_generate('explain this query: ...'); And it will always return the same explanation. :) How it works: 1. Greedy decoding- Always pick the highest probability token (no randomness) 2. 8-bit quantization- Same numerics across all platforms It's easy to get started: uv tool install steadytext echo Hello | st https://ift.tt/Sq6iDfJ July 4, 2025 at 12:27AM

Show HN: I created a privacy respecting ad blocker for apps https://ift.tt/SHd3LC0

Show HN: I created a privacy respecting ad blocker for apps Hey HN, I’ve been working on developing my ad blocker for the last number of years and am proud to share that I have now released a new feature that blocks ads directly in apps — not just in a web browser. What makes this app ad blocker feature special? - All ad blocking is done directly on device, - Using a fast, efficient Swift-based architecture (based upon Swift-NIO) - Follows a strict ZERO data collection and logging policy - Blocks ads in all apps on iPhones, iPads and Macs It works as a local VPN proxy, so it filters all of your traffic locally without going through any third-party servers. The app ad blocker works across News apps, Social media, Games and even browsers like Chrome and Firefox. After using ad blocking in Safari for a long time, it is eye-opening how many ads and trackers are also embedded in apps themselves. The app is available via the App Store, with a 30 day free trial, before an annual subscription is required. I know there are many other ad blockers available, but I hope the combination of performance, efficiency and respect for privacy will mean that this particular feature is a valuable option. It also took a LOT of work to get this working seamlessly within the App Store and iOS / macOS limitations, so am glad the app has been able to finally be released into the world. Full details on the feature are in the release post: https://ift.tt/WkLJSYQ https://ift.tt/WkLJSYQ July 3, 2025 at 06:34AM

You can adjust the day thresholds and label colors in the workflow file, and choose whether labels update daily or only when they cross the next threshold. *Why?* I often lost track of how long tickets had been lingering, especially in older projects. A quick glance at the issue list or github project now tells us what’s fresh, what’s getting stale, and what’s officially ancient. It’s also handy for post-mortems: sort by red labels to see which bugs took the longest to close. *Link* https://ift.tt/pWz520B... https://ift.tt/RrZx8z7 July 3, 2025 at 03:15AM

Along the way, we ran into the same frustrations: - A drawer full of empty coffee bags. - No simple way to track grind size, rest dates, notes—by bean. - My coffee history scattered across photos, screenshots, notebooks, and half-memories. - The unique traits, people, and stories behind each coffee disappearing from the internet once it sold out (since coffee is an agricultural good) - In our opinion, no coffee tool really captures the flavor, emotion, and aesthetic of great coffee—from a design perspective. So we built BeanBook—a coffee notebook log beans, extract recipes, and organize your coffee life in one place with just a snap, powered by AI Here’s what it does: - Snap a bag → Auto-detects roaster, origin, process, roast date, notes, producer, farm, and more - Paste a YouTube link or photo → Extracts a structured recipe automatically - Log grind size, roast timeline, ratings & notes → All saved in a clean, elegant UI - See your coffee year in review → Track habits, trends, and favorites - Ask BeanBook AI → From brew temps to bean facts, get instant answers My co-founder and I built everything ourselves—branding, code, and UX design. If you’re into coffee (or trying to get more into it), we’d love your feedback. - Rokey & Eric https://beanbook.app July 1, 2025 at 12:08AM

Show HN: Attach Gateway – one-command OIDC/DID auth for local LLMs We’ve been building local and on-prem agent workflows for open-source LLMs. Engines like Ollama or vLLM ship with no auth, so every team ends up writing the same JWT proxy. Attach Gateway is a single process that sits in front of any model server and handles the boring bits: - verifies OIDC / DID JWTs - adds X-Attach-User and X-Attach-Session headers so downstream agents share the same identity - optional /a2a/tasks/send endpoint for Google-style A2A hand-offs - mirrors prompts + completions to Weaviate (runs in Docker) One `pip install attach-dev`, export a token, run `attach-gateway`, and your local Ollama is protected in under 60 seconds. Repo: https://ift.tt/kYuNLF8 PyPI: https://ift.tt/EFlSuRC Would love feedback – especially from teams doing multi-agent or on-prem work. https://ift.tt/kYuNLF8 June 30, 2025 at 11:38PM
