To fact-check an AI answer, identify the important claims, find the sources behind them, and compare the answer against reliable evidence.

In practice

Good checks include opening cited links, preferring primary sources, checking publication dates, looking for contradictory sources, and asking whether the answer mixes old and new information.

What to watch

Do not fact-check only the parts that look suspicious. Confident, specific statements can be wrong too, especially names, dates, prices, legal rules, and technical limits.
