Second Brain for Mac and Windows
Your AI memory, connected and always available.
The Second Brain adds a persistent memory layer to your AI tools, allowing ChatGPT, Claude, Cursor, Windsurf, and others to work from the same context. It searches memory by meaning, identifies patterns, resolves contradictions, and prevents duplicates. Your data lives in your own Cloudflare account, with open source code and no dependence on an external service. Available for Mac and Windows, it turns your conversations and knowledge into a memory that grows with you.
