Second Brain for AI
Rahil Patel
Self-hosted persistent memory layer that lets Claude, ChatGPT, Cursor, and any MCP client share the same evolving context.
Key features
- Cross-Tool Persistent Memory: One memory layer shared by Claude, ChatGPT, Cursor, Codex, and any MCP client.
- Semantic Recall: Retrieves memories by meaning rather than exact wording, so different phrasings still surface the right note.
- Memory Graph (v2): Memories link automatically or explicitly, and recall can follow hops to surface related context.
- Notion Sync: Connect a Notion workspace and shared pages sync into memory nightly or on demand, staying current as they change.
- Self-Hosted on Cloudflare Workers: Deploy to your own account in about two minutes — memory stays under your control, not a vendor's.
- MCP Tool Set: remember, append, update, recall, list_recent, forget — usable directly from any MCP client or the brain CLI.
- Graceful Degradation: If Vectorize is missing, recall falls back to keyword search with a clear notice and a /health endpoint reports index status.
- Dashboard with Graph View: Web dashboard for browsing memories, managing integrations, and exploring the memory graph visually.
Best for
- Consistent Assistant Context: Keep the same project background, preferences, and decisions across Claude, ChatGPT, and Cursor without repeating yourself.
- Team Knowledge Capture: Use the CLI or MCP tools to store product decisions or interview notes so any AI tool can recall them later.
- Notion-Backed Memory: Share Notion pages with the connection so meeting notes and specs are automatically retrievable by any AI client.
- Self-Hosted Compliance: Run memory in your own Cloudflare account when data cannot leave your infrastructure or be locked in one AI platform.
- Developer Journaling: Save decisions and rationale from your terminal (`brain remember`) and recall them from Cursor while coding.
- Research Continuity: Store leads, references, and open questions once and surface them across whichever assistant you're using that day.
