CodeAlmanac – Karpathy-style codebase wiki from your conversations

In plain words

CodeAlmanac is an open-source wiki that automatically updates from conversations with AI coding agents. Designed for developers using Claude or Codex, it maintains documentation within a repository that stays current without manual upkeep. The tool solves the problem of knowledge getting lost in chat histories or becoming outdated in static markdown files by automatically capturing and organizing insights from coding conversations in a structured, searchable format.

A codebase wiki for AI coding agents. Captures what the code can't say: decisions, flows, invariants, gotchas. - AlmanacCode/codealmanac

In the maker’s words, at launch

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…

  A Karpathy-style LLM wiki your agents maintain (Markdown and Git)Apr 2026 · github.com · ▲260

  I shipped a wiki layer for AI agents that uses markdown + git as the source of truth, with a bleve (BM25) + SQLite index on top. No vector or graph db yet. It runs locally in ~/.wuphf/wiki/ and you can git clone it out if you want to take your knowledge with you. The shape is the one Karpathy has been circling for a while: an LLM-native knowledge substrate that agents both read from and write into, so context compounds across sessions rather than getting re-pasted every morning. Most implementations of that idea land on Postgres, pgvector, Neo4j, Kafka, and a dashboard. I…

  Auto Wiki – Turn your codebase into a Wiki2024 · wiki.mutable.ai · ▲183

  Hi HN! I’m Omar from Mutable.ai. We want to introduce Auto Wiki (https://wiki.mutable.ai/), which lets you generate a Wiki-style website to document your codebase. Citations link to code, with clickable references to each line of code being discussed. Here are some examples of popular projects: React: https://wiki.mutable.ai/facebook/react Ollama https://wiki.mutable.ai/jmorganca/ollama D3: https://wiki.mutable.ai/d3/d3 Terraform: https://wiki.mutable.ai/hashicorp/terraform Bitcoin:…

  How we leapfrogged traditional vector based RAG with a 'language map'2024 · twitter.com · ▲162

  TL;DR: Vector-based RAG performs poorly for many real-world applications like codebase chats, and you should consider 'language maps'. Part of our mission at Mutable.ai is to make it much easier for developers to build and understand software. One of the natural ways to do this is to create a codebase chat, that answer questions about your repo and help you build features. It might seem simple to plug in your codebase into a state-of-the-art LLM, but LLMs have two limitations that make human-level assistance with code difficult: 1. They currently have context windows that are too small to…

  Repo2vec – an open-source library for chatting with any codebase2024 · github.com · ▲93

  Hi HN, We're excited to share repo2vec: a simple-to-use, modular library enabling you to chat with any public or private codebase. It's like Github Copilot but with the most up-to-date information about your repo. We made this because sometimes you just want to learn how a codebase works and how to integrate it, without spending hours sifting through the code itself. We tried to make it dead-simple to use. With two scripts, you can index and get a functional interface for your repo. Every generated response shows where in the code the context for the answer was pulled from. We also made it…

  My Attempt to Organize the World of AI Dev Tools2025 · aicode.danvoronov.com · ▲101

  I've been exploring the (not so=) amazing potential of AI in coding and have compiled a list of tools. From AI-powered IDEs to code generators, this resource is my contribution to the community. I'm still on the fence about including txt2sql projects, as their functionality seems too basic to me. And I'm personally maintaining this, so your feedback is wellcome.

  Talanoa▲341

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
