Why ask three AIs the same thing
In India, these chatbots led referrals to websites: in September 2026, ChatGPT had 77.25% of the traffic AI chatbots referred to websites, Gemini 16.04% and Perplexity 3.62%, according to StatCounter. They are built differently. Perplexity, for one, is designed around searching the web and showing where its answer comes from.
On the same question, they often agree on the basics and differ on the details: a figure, a step, a risk one of them doesn't mention. Asking all three is a quick way to see what's solid (they all say it), what's uncertain (they disagree) and what nobody covered.
How to compare fairly
- Ask exactly the same question, with the same context, in a fresh chat in each AI. A long chat already steers the answer.
- Don't let one see another's answer before you compare. Otherwise you're comparing an answer with its echo.
- Compare claims, not style. One may sound more confident, or list more sources. That alone says nothing about who's right.
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. That's your common ground.
- Mark where they differ, and note which one gives a reason or a source.
- Mark what only one covers. Ask the others about it.
- Write down what's still open: the questions none of them settled.
It works, but with three long answers it takes a while, and it's easy to miss a difference buried in a paragraph.
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.
Check the account limits in the tool box below. You can also compare two of them in Uncook and check the third by hand with the steps above.
What to do with the comparison
Questions people ask
Which is better: ChatGPT, Gemini or Perplexity? It depends on the question, and it changes as the models change. Comparing them on your own questions tells you more than any ranking.
Can I compare all three at once? A pack or Pro is needed beyond the free account’s allowance; see the limits in the tool box below.
Does a summary tell me which answer is right? No. Check the claims against a reliable source and compare their claims, sources and omissions.

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.
