Every AI conversation starts from zero. Your projects, decisions, and preferences disappear as soon as you close the chat. Second Brain fixes that. It is a self-hosted memory layer that works with Claude, ChatGPT, Cursor, and any MCP client. You can store context once and recall it by meaning instead of keywords. It includes duplicate detection, semantic search, and a web UI. Built on Cloudflare, it offers a free tier and your data remains yours. MIT licensed.
This is the 4th launch from Second Brain for AI. View more

The team stuff got the headline. Here is what else went into v3.
Your memories are better at knowing how they relate to each other. Before, everything was connected to everything in the vaguest possible way, which is another way of saying nothing was really connected. Now a memory can know that one thing came after another, or caused it, or was the decision that settled it. It also stopped connecting near-identical notes to each other and calling that an insight.
Setup got a proper going over. We had people who were not me try to install it and write down every place it annoyed them, which was humbling and useful in that order. It now checks it is pointing at the right account before it starts making changes, warns you properly before anything irreversible, and works in Italian.
If someone invites you to a team, you get an actual product rather than a wall of "admins only". You can see who wrote what and when. Invites work without you explaining them in Slack afterwards.
