Show HN: CodeAlmanac – Karpathy-style codebase wiki from your conversations

CodeAlmanac is an AI-powered tool that automatically generates and maintains a markdown-based wiki for codebases by extracting knowledge from developer conversations with AI assistants like Claude or Codex. The system runs locally on macOS, indexes wiki content, and uses background jobs to continuously sync conversations, identify knowledge gaps, and improve documentation organization. It aims to capture context that code alone cannot convey, such as design rationale, past issues, and cross-file workflows.
