Uploading a document used to mean you still had to point the assistant at it every time. As of today, anything in a Space'sKnowledge is searched automatically — and answers come back with the source attached.

Documents and spreadsheets build live beside the chat.
Ask, don't attach
Add your PDFs, notes and reports to a Space's Knowledge once. From then on, when a question is answerable from those documents, the assistant pulls the relevant passages on its own and answers from them — no re-attaching, no "please read this file first."
Every answer shows its source
An AI answer you can't check is just a confident guess. So when a reply draws on your documents, it tells you which one — click through and verify. That's the difference between a plausible answer and one you can act on.
Watch it index
When you add a document, you'll see its status move from Indexing to Indexed (or Failed, if something's wrong with the file) — so you always know what the assistant can actually draw on, rather than wondering whether an upload "took."
Where it lives
Knowledge is per-Space, so a client's documents stay in the client's Space and never surface in your personal chats. Combined with that Space's memory and connected apps, the assistant answers with the full picture of that project — grounded in your material, with the receipts.
Try it yourself
Every model, one memory, and agents that work the way you do.
