Overview
ButlerBrain
Persistent semantic memory for AI assistants, over the Model Context Protocol.
Save a thought, document, web page, or PDF to your brain once — then recall it by meaning from Claude, ChatGPT, or any MCP-compatible client. One memory, every AI, no re-explaining.
What you can do
- Save anything — notes and thoughts, full web pages, PDFs, and calendar events
- Recall by meaning — semantic vector search across everything you've saved, not just keyword matching
- Use it everywhere — the same brain is available in Claude, ChatGPT, and any client that speaks MCP
- Bring your own knowledge — sync an Obsidian vault, crawl web pages, or ingest documents
