Once you've connected an app, you can fact-check a document from a chat with your assistant. The assistant gathers your document and its sources from the conversation and hands them to Rosey.
Steps
Make sure the document you want checked is in the conversation — pasted, attached, or produced by the assistant earlier in the chat.
Make sure the supporting material is there too — the sources Rosey should check the document against.
Ask your assistant to fact-check it with Rosey. Natural phrasings work: "fact-check this with Rosey," "have Rosey verify this against the sources," "run this through Rosey."
Your assistant calls Rosey, and the results come back in the chat.
Reading the results
Rosey returns each quantitative claim with a status — Supported, Unsupported, or Contradicted — and surfaces the unsupported and contradicted ones for you to act on. See: How fact-checking over MCP works for what each status means.
Tips
Give Rosey the right sources. It verifies against the material it receives, so include the documents you want treated as authoritative.
Re-check after edits. Each fact-check runs against the current version, so run it again after you revise. Each fact-check counts as one run.
