AI Knowledge Base & Synthesis
We all accumulate knowledge — notes, articles, bookmarks, meeting transcripts, research — but most of it ends up scattered and forgotten. Second Brain is a personal knowledge base that uses AI-powered semantic search and knowledge graph visualization to make everything you have ever learned searchable, connected, and synthesizable. It does not just store your knowledge — it helps you think with it.

Core Features
Semantic Search
Find information by meaning, not just keywords. Ask natural language questions and get relevant results from across your entire knowledge base, no matter how things were originally filed.
Knowledge Graph
Automatically maps connections between your notes, documents, and ideas. See how concepts relate to each other in a visual, navigable graph.
Auto Connection Discovery
AI continuously analyzes your knowledge base to surface connections you did not know existed. Finds patterns and relationships across documents, topics, and time periods.
Multi-Format Ingestion
Feed in text files, PDFs, web clippings, markdown notes, meeting transcripts, and more. Second Brain normalizes everything into a unified, searchable knowledge layer.
AI Synthesis
Ask questions that span multiple documents and get synthesized answers with source citations. Not just retrieval — genuine knowledge synthesis across your entire corpus.
Interactive Graph Explorer
Browse your knowledge visually with an interactive graph interface. Click nodes to explore connections, zoom into clusters, and discover the structure of your own thinking.
