Edit an email without losing a detail
A rushed internal email with a moved meeting, a budget cap, a deadline and a confidentiality request. The rewrite must keep every detail and promise nothing new.

Run the test
- Download the file for the AI.

Paste the whole file (the email and the task under it) into the AI.
- Open the AI in another tab, in your own account, start a fresh chat, attach the file and paste the prompt.
- Note what you used: the plan, the visible model or mode, whether web search was on, how many attempts it took and anything that went wrong.
- Score the answer with the checks below. Run the same kit in each AI you are choosing between, or paste their answers into the blind review.

Compare answers blind
Paste the answer each AI gave, score them without seeing which AI wrote which, then reveal. You ran the tests yourself, so you may still recognise a style: hiding the names reduces that bias, it does not remove it. The answers stay in this tab and are never saved or sent anywhere; only the scores are kept, on this device, when you reveal.
Reference answer (open after you score)
Every item in the checklist is in the original. A common failure is dropping the time zone or the confidentiality request, or inventing an agenda.
