How to check an AI answer against the facts
Compare each claim with what you supplied or can verify. Mark the gaps. Then add one relevant fact and see whether the answer changes for a reason you can follow. The final judgement stays with you.
Start with the facts you gave it
For a writing task, put the source beside the rewrite. Check the dates, names, quantities, and words that carry uncertainty. In the recorded project update, both replies keep all six dates and fit the 80-word limit. The first drops the explicit point that nobody knows whether the third reviewer tried the prototype.
A reply can meet a length limit and still lose a qualification. Keep the qualification in your own version if it matters to the people reading it.
Mark claims you did not supply
Underline claims about what happened, what someone knows, or what an option will cost. Ask where each came from. In the newsletter decision, nen calls the later launch an option with “zero readers”. The prompt says twenty people were promised the first issue; it gives no reader count for either date.
The first answer also says two hours is enough to ship. That may be true, but the prompt does not establish it. You can ask for the assumption to be stated, check it yourself, or make the decision without that claim.
Change one fact and reassess
A follow-up tests whether the answer can use new information. In the newsletter conversation, all twenty people accept the later date. nen changes its recommendation to 9 October, which follows the changed promise. It also treats this week's two-hour limit as though it applies next week. The useful revision and the unsupported claim sit in the same reply.
In the delayed-notes conversation, the new fact is that the notes were sent Wednesday morning. The second reply takes that in, then treats sending the notes as proof that the colleague received them and had enough time to prepare. Neither point is established.
Keep your own judgement
Use what survives the check. The model can help rewrite a sentence, expose an assumption, or change course when a fact changes. You still decide whether the recommendation fits the situation and whether a missing fact needs checking.
A practical follow-up is specific: “Which parts of that answer depend on facts I did not give you?” Treat its next reply with the same care. For reflection, the reflection guide shows how to record your own conclusion and return to it after something happens.
