Nucleus

Knowledge Infrastructure for AI

Visit Nucleus

Nucleus is a knowledge infrastructure for AI. It ingests documents (PDFs, notes), emails (Gmail, Outlook), and web content (URLs, Google Drive), then organizes them into a searchable knowledge base with a knowledge graph. Users can ask natural-language questions and get answers with cited sources. It works with any AI tool (ChatGPT, Claude, Gemini, Cursor) via MCP connectors and provides a REST API for programmatic access. The platform also includes COVE (Chain of Verification), which extracts and verifies claims against the knowledge base to detect hallucinations.
