Prove It · A Question Somebody Else Asked
Publish a question and its answer card

What a card does and does not prove. This site did not watch your AI answer. The card records who you say answered it and the sources you gave, and nothing more. What anyone can check is that the card has not changed since you published it: its address is computed from its own words.
