How it works

Pick a prompt or write your own. Prompt Bench sends it to each engine, saves the complete answer with a timestamp, and detects mentions and citations for your brand and competitors.

Try it yourself

Every diagnosis includes three high buyer-intent prompts you can click to run live, so you see real answers in seconds.

Connected to the fetch

When an answer cites a competitor, compare it with the two-fetch diff of your own page. The gap usually explains the answer.
