Show HN: PaperSync, making ArXiv papers collaborative https://ift.tt/qiT8otP

Show HN: PaperSync, making ArXiv papers collaborative Demo: https://youtu.be/pnznDL9SZvI PaperSync was a project was made by two CS freshmen, Matthew Li (me!) and Michael Li, in 24 hours during HackCMU. At a high level, we built PaperSync to make reading research papers easier and more collaborative. Users can reference any part of the paper, ask anything they want, and have other users reply, all within the paper itself! If you are interested in our work, we would love to talk!

Show HN: From selling AI to QA teams to building a smooth test-management app https://ift.tt/20t6W3v

Show HN: From selling AI to QA teams to building a smooth test-management app Hey HN, Bootstrapped founder here. I've got a bit of a story for you. We started desplega.ai to build a sophisticated AI platform that could automate E2E testing. We spent the last few months talking to dozens of QA leaders, and trying to learn what are their actual challenges. We've got one consistent feedback from large teams: their daily reality is a living hell of slow, clunky tools. We're talking about teams at major companies still managing tests on spreadsheets. Or they're stuck in a Jira instance so customized and slow you can “make a full pot of coffee” while a page loads (and that’s why they acquired arc! t3.gg said it first). On top of that, they're paying 2k/mo+!? for these tools that feel like they were designed in ‘05. Soon, it became obvious that our AI tool was way too advanced for them, and why it was much easier for younger startups to start using us. But we didn't want to give up on them just yet so... Because I grew up when the internet was still free, and I actually miss that a lot, we decided to create a free test management tool. Our vision is still AI, but we learned AI is not the silver bullet large teams are wishing for. (We wrote something about it at https://ift.tt/dnrYyCo ). Our hypothesis right now is that we can be that team building the right tools for each QA team, leveraging AI. We would love to hear your thoughts on (a) Should we make the project open-source? Any key features? (b) Would you ever trust an entity to do your QA first pass? Cheers, https://ift.tt/yIOPd7Y September 15, 2025 at 12:12AM

Show HN: council - ai groupchat of ctos (no more asking ai to roleplay) i made a council of advisors to help me code. as a self taught dev, ive been heavily reliant on ai for the past two years. found myself often prompting claude to take on different personalities, so i built a web app. it's great for the step before telling cursor what to do and reviewing prs once theyre ready.

Show HN: MediaMouth – I created a comment section for movies and TV shows https://ift.tt/dhjXrgD

Show HN: MediaMouth – I created a comment section for movies and TV shows I tend to watch TV shows months or sometimes years after they air, and by that time, all the discussions are lost in internet oblivion. I wanted a space where I could join the conversation anytime. So I created one. MediaMouth makes it fun and easy to talk about the media you love. Conversations are organized season by season, episode by episode, so you never have to scroll through chaotic hashtags to join in. We’re looking for feedback on usability, ways to improve, and hopefully gain some new users. We’d love to hear your thoughts! You can download the iOS Beta or watch the video walk-through on our website: www.mediamouthapp.com https://ift.tt/M8IysSo September 14, 2025 at 01:06AM

Show HN: I built an open source drag and drop editor for Genkit AI flows https://ift.tt/1c3u4ms

Show HN: I built an open source drag and drop editor for Genkit AI flows Hi, I have been building small AI Agents for quite some time now using various frameworks and one thing that always bugged me was that iterating on small things like prompts, flows, tools etc always took a code change + deployment of the app. While the prompt part can be solved with Langfuse I haven't found a good way to keep the flow management remote (and open source). Lately I have been working with Genkit ( https://ift.tt/bNPguZj ) and love how modular it is. So I thought why not build a UI builder on top of that that can handle simple flows, prompts and basic tracing. And here we are with a first early version: https://flowshapr.ai Repo: https://ift.tt/sTCxAiN This first release can - Manage and execute simple flows remotely - Works with GoogleAI, Anthropic or OpenAi - Integrate with remote MCP tools - API Endpoint to execute flows remotely - Flows and flow urls are compatible with the genkit client sdk Upcoming - Support for Ollama - Support for various vector stores - More complex multi agent flows - Session management Any feedback and suggestions are welcome!
