A client proposal explains what you will do, what it costs and when you can deliver it. AI can help draft one, but you still need to know whether it says what you intended before sending it. Verification checks the finished work against its requirements and sources. Does the price match your notes? Does the total add up? Can the client tell what you are asking them to approve?

Suppose your notes say “Friday delivery is tentative,” but the draft promises Friday. A confident assurance from the drafting assistant does not settle that difference. A reviewer, a person or AI assigned to check the work, needs the original request and notes. The source shows whether the promise is supported. An AI reviewer in a separate conversation can offer another reading, but ask to see the evidence behind its verdict.
