Second Brain: Personal Knowledge Management Powered by AI

Your Personal AI Knowledge Base

Second Brain stores and indexes your documents, notes, code, and web clippings. When you ask a question, it searches your personal knowledge base first, then augments with AI — giving you answers grounded in your own context and notes.
