mind is a single file memory layer for AI-assisted development. It reads your conversations from Claude Code, Gemini, Cursor, Codex, and Copilot after every commit and synthesizes them into one token efficient mind.md that every tool can load as context.
I built this because I kept hitting the same wall across projects — every AI tool has its own rules, its own memory, its own prompt format, and none of them talk to each other. You can configure behaviors per tool (rules and skills etc), but there's no shared, consistent context that travels with the project. So I'd find myself re-explaining the same architecture decisions, the same gotchas, the same "we tried that and it didn't work" notes to a different model every other day.
mind is the simplest fix I could think of: one file, written and updated by LLM after each commit, aggregating context from every tool you use into one place.
pip install project-mindcd your-project
mind init # creates _mind/, installs git hook, writes mind.toml
mind sync # extract transcripts and rebuild mind.md
mind status # show tracked tools and last syncThe git hook runs mind sync automatically after every commit.
| Tool | Source |
|---|---|
| Claude Code | ~/.claude/projects/{slug}/*.jsonl |
| Gemini | ~/.gemini/tmp/{project}/chats/*.json |
| Cursor | ~/.cursor/projects/{slug}/agent-transcripts/ |
| Codex | ~/.codex/sessions/**/rollout-*.jsonl |
| Copilot | VS Code workspaceStorage/{hash}/state.vscdb |
- After every
git commit, the hook runsmind syncin the background. mind syncfinds transcripts newer than the last sync and extracts the user + assistant text.- It calls your configured LLM with the extracted content and the current
mind.md. - The LLM rewrites
mind.md— compressing old entries, adding new ones, preserving the sections you care about.
