Second Brain
An AI-powered personal knowledge manager that understands you.
What it does
Second Brain connects to the tools you already use — Google Drive, Gmail, Apple Calendar, iMessage, and more — to build a living picture of your projects, priorities, and writing style. Then it helps you get things done with an AI assistant that actually knows your context.
