Why people use more than one AI
Many Americans already use several assistants. In a Pew Research Center survey from February 2026, 44% of US adults said they use ChatGPT, 24% Gemini and 6% Claude. Each is built and trained differently, so on the same question they often agree on the basics and differ on the details: a number, a step, a risk one of them leaves out.
That's useful. Where they all agree, you're on firmer ground. Where they differ, you've found what to check.
How to compare fairly
- Ask exactly the same question, with the same context, in a fresh chat in each AI.
- Don't show one AI another's answer before you compare.
- Compare claims, not style. A longer or more confident answer isn't a better one.
Agreement isn't proof.
Three AIs agreeing makes a point more likely, not certain. For anything that matters, check it against a source you trust.
Compare them by hand
- List the claims in each answer, one line each.
- Mark what all three say.
- Mark where they differ, and which one gives a reason or a source.
- Mark what only one covers. Ask the others about it.
- Write down what's still open.
It works, but with three long answers it takes a while.
Keep the main points together with Summarize
Ask each AI the same question in a fresh chat, then compare their claims, sources and omissions. If you want a shorter version of several chats, choose Summarize in Uncook; the task cost is shown before you start. A summary does not check which answer is correct.
The free-account limit is shown in the tool box below. To compare all three in one go, use a pack or Pro. Otherwise compare a pair in Uncook and check the remaining answer by hand.
What to do with the comparison
- Keep going with the best one: carry the chat over with Handoff, or start fresh with a handoff.
- Bring the good parts together: Merge turns several chats into one prompt.
- Share it: export the comparison as PDF, Markdown, text or Word, or share it as a page.
Questions people ask
Which is best: ChatGPT, Gemini or Claude? It depends on the question, and it changes as the models change. Comparing them on your own questions tells you more than any ranking.
Does a summary tell me which answer is right? No. Check the claims against a reliable source and compare their claims, sources and omissions.
Can I compare all three at once? Yes, with a pack or Pro. The free-account limit is shown in the tool box below.

We don't keep the conversations you bring. When you click Send to Uncook in the extension window, the extension sends the chat from your tab to our servers, encrypted, for up to 30 minutes, and we delete it as soon as your Uncook page opens it. What Uncook makes from it is kept as a task, for as long as our Privacy page says. Neither your chats nor your tasks are used to train AI models.
