cogito-mem

Long-term memory for Claude Code, on your own machine. Cogi the squirrel keeps every message you and Claude exchange, and brings back what Claude forgot. No API key, no cloud, no AI calls to store.

Cogi: Claude forgets. Cogi doesn't.

docs tests license

Why try it

  • Claude stops forgetting. Every message and reply is kept word for word, with its date. When something has dropped out of the context window, or happened last week, the relevant part comes back with your next prompt.
  • It remembers what you did, too. Commands you ran (and whether they failed) and files you touched, without their output.
  • Private and free. One folder on your computer. No account, no API key, no AI calls to save a message, nothing leaves your machine.
  • Tested. On the LoCoMo benchmark, the 1,000 tokens Cogi hands back answer 74.7% of questions right, level with rereading the whole conversation (76.5%). A search over 10 million tokens takes 26 ms on a laptop CPU. See the results.

Install

With uv installed, one command in a terminal:

claude plugin install cogito-mem --marketplace meridian21lab/cogito-mem

That's it. To get updates, turn on auto-update once: /plugin → Marketplaces → cogito-mem → Enable auto-update. The first start downloads the model (310 MB, about a minute). Step-by-step guide · Codex, Claude Desktop, Docker

Try it

  1. Tell Claude: Let's call the staging server "acorn".
  2. Clear its short-term memory: /clear
  3. Ask: What did we call the staging server? Claude answers "acorn": Cogi brought it back.

How it compares

cogito-mem claude-mem Mem0 plugin cognee plugin Supermemory plugin
AI calls to store a message none an observer model per tool call (Haiku on your Claude plan by default) extraction on Mem0's servers extraction with your LLM key or claude -p in Supermemory's service
Account or API key none optional sign-in Mem0 Platform API key an LLM key or the Claude CLI API key or login
Where your memory lives your computer your computer (cloud sync optional) Mem0's cloud your computer (cloud optional) Supermemory's cloud (local mode available)
What comes back your exact words, with dates AI-written observations extracted memories graph facts and summaries extracted memories
Searchable after the same turn the observer's run a batch (every 5 exchanges) the next graph run the background save

Keep your project's rules in CLAUDE.md, and let Cogi remember what happened.
