The task
Plan a 3-day trip to Tokyo for two friends, with a budget of $1,000 for the two of them (flights not included).
Prompty's prompt is already written and sealed. This is its fingerprint, so nobody can change it later. We reveal the prompt when the challenge ends, and you can check it matches.

How the winner is picked.
-
Both go to ChatGPT
Your prompt and Prompty's prompt are each sent to ChatGPT, in a fresh chat with memory turned off.
-
Three blind judges
Claude, Gemini and Grok see "Answer A" and "Answer B", never whose is whose.
-
Two of three wins
If at least 2 of the 3 judges pick your answer, you beat Prompty.
-
Earliest wins a tie
If more than one person beats Prompty, the one who sent their prompt first wins.

- Free to enter. You must be on the Prompty waitlist with a confirmed email (sending a prompt here adds you; just confirm the email we send).
- One prompt per person, and it can't be changed once it's sent, so make it your best. Entries close on 1 December 2026, 00:00 UTC.
- Your prompt must be your own, in plain text, and only for the task above. No instructions aimed at the judges and nothing harmful or illegal, or the entry doesn't count.
- You must be 13 or older. If you're under 18, you need a parent's or guardian's OK to enter and to accept the prize.
- The prize is 10 years of Prompty Pro on the winner's account, starting when Prompty launches. It has no cash value and can't be swapped or passed on. If Prompty stops running, the prize ends with it.
- We contact the winner by email. If they don't reply within 14 days, the next person in line who beat Prompty wins.
- If nobody beats Prompty, there is no winner, and we'll show everyone how close you came.
- We may share entries (your prompt and your first name) in our posts and videos. Your email is never shown or shared.
- Lumly runs this challenge and its decisions are final. It's void where the law doesn't allow it. See our privacy policy.
