memgit — git for AI memory

Your AI assistants forget everything when the session ends. memgit fixes that.

Version-controlled, cross-AI context that persists, diffs, rolls back, and syncs like code. Switch from Claude to Cursor to ChatGPT mid-project — your context is already there.

Why not claude.md? Why not mem-search?

You've probably already tried both. Here's why they hit a ceiling:

Proof — context costs you can measure

Run this on your own store to see the actual numbers (measured where possible; estimates labeled):

$ memgit stats

  Total memories:   108   (41 feedback · 23 user · 19 project · 12 reference · 8 convention · 5 lesson)
  Priority:          3 critical · 67 medium · 38 low

  Context footprint  (measured where possible; estimates labeled)

  Surface                                             Tokens
  Full store (every memory as context)                12,840
  Resume digest  (measured render)                       540
  Recall block  (estimate: top-3 rules ≈ chars/4)        ~60

  per-session injected ≈ 600 tokens (estimate) vs 12,840 tokens if the full store were loaded

Why such a big difference? claude.md loads all context every session. memgit injects a bounded resume digest plus BM25-matched recall — only what is relevant to this session, not everything you've ever recorded. The digest is measured by actually rendering it, and the store total is the real corpus size; nothing here is a simulated benchmark.

The git analogy is literal

memgit's data model maps exactly to git:

This is not metaphorical — memgit uses a content-addressed object store (SHA-256 blobs) identical to git's architecture. Every memory has a stable SHA. Identical content has identical SHAs. Old state is always recoverable.

The store IS a git repo

Every memory is a readable .toon file under memories/. Push your entire memory set to GitHub with standard git:

memgit git init --remote git@github.com:yourteam/ai-memory.git
memgit git push

Teammates pull and start with your AI's learned rules from session 1:

git clone git@github.com:yourteam/ai-memory.git ~/.claude/memgit-store
memgit setup all

You can grep, git blame, and git diff your memories just like code:
