Show HN: CodeAlmanac – Karpathy-style codebase wiki from your conversations Hey HN! This is Divit from Almanac (YC S26). We built CodeAlmanac, a wiki for your coding agents that updates as you talk to them. It is open-source, local, and free. Here’s a demo: https://www.youtube.com/watch?v=XNQWV3TFBWM Your CC/Codex conversations contain a LOT of knowledge that is forgotten because it was never documented. People have their own methods of documenting their chats. We used to make Markdown files like MANUAL.md and DESIGN.md, and would prompt Claude to keep them updated. The problem is that these files quickly become outdated and messy, and there’s only so much you can put in a single file. So we set out to build CodeAlmanac. We wanted something that was 1) maintained automatically, 2) lived inside our repository, and 3) used our existing Codex/Claude Code subscriptions.

I started a building a tool that accepts a picture of the dice and quickly answers if the roll can be solved. Well, that quickly devolved into building a highly-optimized solver efficient enough to run in the browser on WebGPU. Once the solver worked, it turned into an excuse to finally explore multiplayer game dev, which I did with PartyKit and some Cloudflare primitives (durable objects, D1, workers). During this process it all became an actual game I shipped. Where the games features ended up: - A "daily" mode where everyone gets the same 12 tiles each day, and the scoring goal randomly changes (most words, longest word, most crossings, rarest words) tracking streaks and leaderboards. - Real-time multiplayer - 1v1, or drop an invite link into a group chat and up to 10 people race ...
