What is Second Brain?

Second Brain is a self-hosted memory layer that works across every AI tool — Claude, ChatGPT, Cursor, and anything else that supports MCP. Store notes, decisions, and context once, then recall them by meaning across every session.

Built on Cloudflare Workers + D1 + Vectorize. One-click deploy, free tier, your data stays in your own account.
