**A collaborative substrate for your agents.** Your data. Your agents. One shared brain. Toolbelt is a collaborative substrate over your data. Discover documents, structured data, events, entities, and relationships across agents and sessions. Better answers. Fewer tokens. Curated context, not raw access. ### Three things make it different - **Knowledge extraction.** Upload any document — entities and relationships extracted automatically, queryable immediately. - **Hybrid retrieval.** Ask questions that span structured tables, documents, and relationships in a single call. No stitching databases together. Orchestrates semantic, structured, and hybrid retrieval. - **Shared workspaces.** Share the URL and any agent can query the same workspace — like a shared Google Doc for your data. ### Quick start Free anonymous account auto-provisions on first connect — no signup required.
