Market research in Claude: personas show before launch which version holds.
Until now, the sign-off round decides. Every persona is researched from public customer voices, with quote and source. You don’t need traffic, and the live test comes after.

Retired craftsmanVoterOne sentence in Claude is enough. For example:
- Test a page
“Test my homepage against my target audience and write a better version.”
You get the new version to approve first, then the verdict.
Try it free → - Compare headlines
“Which of these two headlines gets more clicks with my customers?”
You get which one leads, and for each persona the objection the other one gets stuck on.
Try it free → - Check competitors
“Which claims on my page do my competitors make the same way?”
You get each key claim marked taken, contested or open, with a verbatim quote and its source.

Whoever objects loudest gets their way. Then it goes live, and you wait weeks for data.
You know the third round of revisions. Nothing was tested anyway.

Too little traffic for an A/B test?
Then check before, not live. A small page never reaches a significant result. You need the verdict before the first click.

The leaders test before launch.
Whoever tests the message first starts with the better version. Whoever approves by taste pays with budget and weeks.

What it feels like when it works.
You know before launch which version carries. And you know why: where the personas get stuck, get confused or drop off.
Why not just ask Claude?
The 99takes jury runs on Claude too. The difference is who the model plays.
Ask it yourself and the model guesses who buys from you.
Two prompts often give two opposite verdicts.
The personas come from competitor copy and public customer voices, each with quote and source.
✓10 to 14 personas read the same copy, each also under the others’ jobs.
You see where it keeps snagging.
Not made up, looked up.
Every persona is researched from public customer voices, with quote and source. This one comes from the audience we tested this page with.

AI generated Freelance copywriterSimulated persona · 2 sources “Quote and source” right at the top gives me something I could show my client, instead of just another AI verdict.What holds her back
My clients already come with ChatGPT feedback. I worry this result also looks like just another AI opinion to them.
Simulated persona, translated from German. Run of 12 Oct 2026: the hero of this page against the previous version.
What a result looks like: Tappla.
Tappla is our own SaaS for TV apps, sold in the US. We tested the tappla.com hero from July 2026 against a new version, with 12 personas from its audience.
Screenshots of tappla.com. Same page, only the hero copy swapped: that is how it was tested. 12 personas, 48 verdicts, 12 Oct 2026.

Four jobs, one conversation in Claude.
How often was the jury right?
The live test comes after. You report which version won in the market, and 99takes calculates the hit rate per jury from it.
A simulation is not a market measurement. It comes before an A/B test with real traffic and does not replace it.
