Second Brain

About

Second Brain gives your AI tools persistent memory across sessions. Built on Cloudflare Workers, D1, Vectorize, and Workers AI – all on the free tier. Connect to Claude, ChatGPT, Cursor, Windsurf, or any MCP-compatible client in minutes.

Features: semantic search with time-decay reranking, contradiction detection, tag-based recall, importance scoring, LLM-synthesized insights, and OAuth on the MCP endpoint. Your data lives in your own Cloudflare account – zero vendor lock-in.

Integrations: Obsidian plugin (in the community directory), CLI (npm), Chrome extension, iOS Shortcuts, and a Web UI for browsing and editing memories.

Open source. One-click deploy.

Use Cases

  • Resuming a project in a new AI chat without re-explaining earlier decisions and open threads
  • Exploring an idea in one AI tool and building it in another with the same saved context
  • Keeping writing preferences and project constraints available across Claude, ChatGPT, Cursor, and Codex

Who it is for

  • Developers who use AI coding tools like Cursor, Codex, or Claude and want shared memory between them
  • Individuals who switch between multiple AI assistants and want context to persist across sessions
  • Small teams that want a shared memory layer alongside private personal memory
