Most AI chats start from scratch every time, losing your project history and preferences. Second Brain changes that by providing a self-hosted memory layer that integrates with Claude, ChatGPT, Cursor, and any MCP client. You can save context once and recall it later using semantic search rather than just keywords. It includes features like duplicate detection and a clean web UI. Built on Cloudflare, it offers a free tier while keeping your data entirely under your control under an MIT license.
