Show HN: TapeHead – A CLI tool for stateful random access of file streams https://ift.tt/c47s35z

Show HN: TapeHead – A CLI tool for stateful random access of file streams I wrote this tool while debugging a driver because I couldn't find a tool that allowed me to open a file, seek randomly, and read and write. I thought it might one day be useful to someone too. https://ift.tt/h46IjxD December 7, 2025 at 01:53AM

Show HN: Manifesto – An AI-Native UI Framework Intent-to-State, Not Text-to-App https://ift.tt/ojLQZ3E

Show HN: Manifesto – An AI-Native UI Framework Intent-to-State, Not Text-to-App Hi HN, I'm the creator of Manifesto AI. I've noticed that while LLMs are getting smarter, their ability to interact with complex Web UIs is still fragile. Agents usually have to "guess" DOM selectors or rely on vision, which leads to hallucinations and broken workflows. I realized that for AI to be useful in SaaS/B2B software, we don't need "Generative UI" (Text-to-App); we need a deterministic "State Layer" that agents can understand and control directly. So I built Manifesto. It's a schema-first UI engine where: 1. You define the form/UI as a JSON Schema. 2. The engine renders it (React/Vue). 3. Crucially, it exports a "Semantic Snapshot" to the AI Agent. Instead of parsing pixels, the Agent receives a clean JSON state (values, validation rules, available actions) and dispatches "Intents" (e.g., `setValue`, `submit`) to the engine. Disclaimer: I built the core engine and this demo in just 4 days. It is currently in a very early Alpha (v0.1) stage. I’m sharing this early because I want to validate if this "Intent-to-State" architecture makes sense to other developers. I'd love to hear your feedback on the approach. Roast my code or the concept!

Show HN: Stateless compliance engine for banking and blockchain https://ift.tt/6H1Ag2V

Show HN: Stateless compliance engine for banking and blockchain I’ve been working on a stateless compliance engine that validates IBAN/SWIFT, OFAC lists, ISO20022 (pain.001/pacs.008), and multi-chain data (ETH, BTC, XRPL, Polygon, Stellar, Hedera). Statelessness feels important in financial and blockchain workflows because no user data persists between requests, outputs are fully deterministic, and auditors can reproduce results without relying on stored state. Current progress: • Deterministic validators live and callable • On-chain checks working across 6 networks • ISO20022 structuring + downloadable PDFs • AWS backend deployed; Azure environment being added for multi-cloud isolation Looking for technical critiques or alternative patterns for building stateless compliance systems. https://ift.tt/86flP59 December 7, 2025 at 12:10AM

Show HN: Bible Note Journal – AI transcription and study tools for sermons (iOS) https://ift.tt/LmoTi23

Show HN: Bible Note Journal – AI transcription and study tools for sermons (iOS) I got back into church a couple years ago and would try taking notes with Apple Notes. It was a struggle trying to type notes while focusing on the sermon. Honestly, it would have been easier to write it in a notebook but in the end I built this iOS app to solve that problem. You can record audio during a sermon (or upload files), and it transcribes using Whisper, then generates summaries, flashcards, and reflection questions tailored to Christian content. The backend is Spring Boot + Kotlin calling OpenAI's API. Instead of deploying the backend through one of the cloud providers directly I decided to go with Railway. Users are notified with push notifications when their transcription and summary are completed. The iOS app uses SwiftUI and out-of-the-box SwiftUI components. I worked with Spring Boot + Java a few years back when in fintech so it was cool to try writing something in Kotlin. I'm also a full-time Flutter dev that has been trying to get into Native iOS development and felt like I found a good use case for an app. Currently only available in the US/Canada App Store. There is a free 3-day trial that you can use to give the app a go. The goal was helping Christians retain more from sermons and build stronger biblical literacy. Happy to answer questions about the architecture, AI prompting approach for Christian content, or anything else.

Show HN: HCB Mobile – financial app built by 17 y/o, processing $6M/month https://ift.tt/KQsCnMi

Show HN: HCB Mobile – financial app built by 17 y/o, processing $6M/month Hey everyone! I just built a mobile app using Expo (React Native) for a platform that moves $6M/month. It’s a neobank used by 6,500+ nonprofit organizations across the world. One of my biggest challenges, while juggling being a full-time student, was getting permission from Apple/Google to use advanced native features such as Tap to Pay (for in-person donations) and Push Provisioning (for adding your card to your digital wallet). It was months of back-and-forth emails, test case recordings, and also compliance checks. Even after securing Apple/Google’s permission, any minor fix required publishing a new build, which was time-consuming. After dealing with this for a while, I adopted the idea of “over the air updates” using Expo’s EAS update service. This allowed me to remotely trigger updates without needing a new app build. The 250 hours I spent building this app were an INSANE learning experience, but it was also a whole lot of fun. Give the app a try, and I’d love any feedback you have on it! btw, back in March, we open-sourced this nonprofit neobank on GitHub. https://ift.tt/1lIHz2X https://ift.tt/nf1mwye December 3, 2025 at 09:50AM
