Same Question Arena

Ask them all the same thing at once. Read the answers without knowing which is which, say what you actually think of them, and find out afterwards. Most people cannot tell them apart, and finding that out about yourself is worth more than any chart we could show you.

Before you type anything

Your question goes to 3 models run by Anthropic. Each company receives the words you type, under its own terms, and what it does with them afterwards is between you and them — we cannot see it and we cannot undo it.

  • Anybody's name, address, date of birth or NHS number, including your own.
  • Account numbers, reference numbers, or anything off a bill or a letter.
  • A question that only makes sense if you paste in the confidential thing it is about.

This is the only thing on the site that sends what you write to more than one company at once, which is why it says so here rather than in a policy you would have to go and find.

The Arena needs an account, because a round uses part of your allowance. Sign in, or read what the makers claim first — that page needs nothing at all.
