Your AI should know who you are.

Sibyl reads your conversations, emails, calendar, and contacts to build a portable context layer. Then any AI you use — Claude, ChatGPT, Cursor — can answer like it's known you for years.

We'll email you when access opens. No spam.
Yours, portable
Sibyl works in any AI tool that speaks MCP, plus a browser extension for Claude on the web. Your context isn't locked to one platform.
Honest privacy
End-to-end encryption on your card. Every fetch is logged. You can delete everything in one click.
Real depth
Not just a chatbot memory. A graph of who you know, what you've decided, what you're focused on — synthesized from your own communications.
