Choose your Space from the picker after signing in. You land in Chat with an empty Knowledge library ready for you to add sources.
Open Knowledge in the sidebar. Upload a file (PDF, Word, Excel, PowerPoint, Markdown, or text — max 50MB) or paste text directly. Wait until the source shows a ready status.
Open Controls to see platform guardrails and the rules that shape how this Space answers. Guardrails always apply. You can enable, disable, or delete unpublished drafts from a rule's menu.
Start a new chat, ask a question about your material, and read the grounded answer. Expand Sources under the response to see which documents it drew from.
