What it does

Meet h5i: The Git sidecar for the AI age. While Git tracks code diffs, h5i versions the AI’s "Reasoning" (Observe-Think-Act) alongside it. Unlike existing tools, h5i structures AI logic as a DAG linked to Git commits, allowing models to instantly restore context after session resets. It stands out with advanced compliance features like "Blind Edit" detection, uncertainty heatmaps, and prompt-injection scanning to ensure AI-generated code is traceable, safe, and reliable.

Fast, security-first headless browser for AI agents. Built for automation, red teaming, web testing, and scraping, with direct HTTP traffic control and auditable sessions. Pure Rust, no Chromium or V8. - h5i-dev/h5i

  Hi HN, I'm the author of git-lrc, would appreciate some feedback from the community Last year my team started using AI coding tools more heavily, and we found ourselves generating tons of code, but spending less time looking at the stuff that's been generated. We felt like we were losing a bit of grip/understanding of what we were building. Regressions occasionally slipped through. Sometimes changes made it all the way to production only to be reverted later. We tried several AI code review tools, but most operate at PR time. That felt too late. I wanted review to happen while the…

  Git for AI AgentsMay 2026 · github.com · ▲129

  hi guys. been working on something i think is fundamentally missing in today's workflow with ai agents. vcs. i find myself struggling with questions that agents can't answer like "why did you do it?", "when did u delete this folder? why?", etc. or trying to /rewind (after a /compact...) or basically `bisect` to find when and why something was done by the agent in the current / previous session. just like git did for code, i think we are the same core capabilities with ai agents so... i developed an open source solution for that (currently supporting claude code) would love to…

  I replaced vector databases with Git for AI memory (PoC)2025 · github.com · ▲198

  Hey HN! I built a proof-of-concept for AI memory using Git instead of vector databases. The insight: Git already solved versioned document management. Why are we building complex vector stores when we could just use markdown files with Git's built-in diff/blame/history? How it works: Memories stored as markdown files in a Git repo Each conversation = one commit git diff shows how understanding evolves over time BM25 for search (no embeddings needed) LLMs generate search queries from conversation context Example: Ask "how has my project evolved?" and it uses git diff to show actual…

  YourGPT 2.0Nov 2025 · yourgpt.ai · ▲215

  Today we are launching YourGPT 2.0, an update focused on making support, sales, and operational workflows work together more smoothly in one system. This release improves how workflows are built, how the platform connects to external tools, and how context is maintained across long, multi-channel interactions. AI Studio now makes it much easier to create and refine workflows. You can describe the process you want in natural language and the system generates the full workflow for you. It can also help debug issues by showing what happened at each step and explaining where things went off…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
