ChatCrystal helps developers organize AI coding conversations from tools like Claude Code and Cursor into clear notes and searchable knowledge. It runs locally on Windows, letting you import chats, summarize them, search by meaning, and build a network of tags to track topics. You configure your own AI services for summarization and search. It works well with Cursor and other MCP-compatible clients to keep your coding insights handy and reusable.

ChatCrystal Demo

ChatCrystal is a local-first AI PKM app for developers who solve real problems with Claude Code, Cursor, Codex CLI, Trae, and GitHub Copilot.

It turns scattered AI coding conversations into structured notes, semantic search, a tag knowledge graph, Markdown exports, and MCP memory your agents can reuse. If this fits your workflow, a star helps more builders find a private, local-first way to keep their AI work memory.
