Normally, AI conversations start from nothing and your preferences vanish as soon as you close the window. Second Brain solves this by acting as a self hosted memory layer that integrates with Claude, ChatGPT, Cursor, and other MCP clients. You can store your project context once and recall it based on meaning rather than just keywords. The platform features semantic search, duplicate detection, and a clean web interface. Because it is built on Cloudflare, it offers a generous free tier while ensuring you keep full ownership of your data under an MIT license.
