Second Brain for AI

Second Brain for AI

Persistent memory for Claude, ChatGPT & Cursor. Free.

Traditional AI conversations often lack continuity, with your valuable projects, decisions, and personalized preferences vanishing as soon as a chat session concludes. Second Brain solves this fundamental problem by providing a self-hosted memory layer designed to seamlessly integrate with popular AI clients like Claude, ChatGPT, Cursor, and any MCP client. You can store important context just once and effortlessly recall it later through semantic meaning rather than relying solely on keywords. This powerful tool includes intelligent duplicate detection, advanced semantic search capabilities, and an intuitive web user interface. Built on Cloudflare, Second Brain also offers a generous free tier, ensuring your data remains completely under your control, backed by an open-source MIT license for full transparency and flexibility.
