Nessie is an AI-native knowledge platform designed for founders, researchers, and anyone who works with large volumes of ideas and content. It connects to your AI chat history (ChatGPT, Claude, etc.) and documents, ingesting and structuring them into a persistent “AI brain” that you own. Users can instantly search, synthesize, and share collections of knowledge—transforming fragmented conversations and notes into living, shareable resources. Nessie emphasizes data ownership and lets users publish or share their “brains” for collaboration or public knowledge sharing, moving beyond static documents to interactive intelligence.
