        Account deletion

        Deleting your account is permanent and can’t be undone. It removes:

        • your sign-in, settings and phone number
        • all your tests, reports and uploaded product photos
        • any unused test credits, including a free test you haven’t used

        Download any reports you want to keep first. We keep payment records for tax and accounting (Stripe keeps its own receipts), and a simplified form of your email address so a deleted account can’t claim another free test. Details are in the privacy policy.

        Quick answers, or send us a message.

        How do credits work?

        Each test uses one test of its size: 1,000, 10,000 or 100,000 AI participants. New accounts get one free 1,000-participant test, if eligible (one per person). You can buy single tests ($19, $69 or $279) that don’t expire while your account is open (unused ones can be refunded within 30 days), or a monthly plan. When you run a test, we use your free test first, then your monthly plan’s tests, then single tests.

        How do monthly plans work? How do I cancel?

        Monthly plans give you 10 tests every month for $49 (1,000 participants), $199 (10,000) or $799 (100,000). Plan tests also work for smaller sizes. Each paid month resets you to 10 tests, and unused ones don’t carry over. The plan renews automatically until you cancel. To cancel, go to Account → Manage or cancel plan. You keep your tests until the end of the month you paid for. To switch plans, cancel and start the new one; it begins right away.

        How long does a test take?

        Usually about 10 to 12 minutes for 1,000 participants, 14 to 16 for 10,000 and 22 to 28 for 100,000. At very busy times it can take up to 24 hours. Your test’s page shows which step it’s on. If a test can’t finish, your credit comes back automatically. You can close the page. We’ll email you when your results are ready (you can turn that off under Account).

        What if a test fails?

        The test goes back to your account automatically (single test, plan test or free test, whichever it used). Run the test again, or message us below if it keeps happening.

        What’s in the PDF report?

        A verdict, a written conclusion, key findings, who to target first, a price to test next, results by audience group, short interviews, risks and suggested validation steps. Bigger tests add version comparisons, an image vote that shows which image works best, a city breakdown and a detailed ad targeting guide (ages, interests, platforms, ad messages, which photo to use and budget split). The wide pages drop straight into a presentation.

        I changed my idea. How do I test it again?

        Open your report and press Re-test, or in a new test choose “Tested this idea with us before?” and pick the test or type its code (like ST-7K4Q2X, on your report and PDF). Your old version comes back as Version A next to your update, and (at the same test size) the same simulated people judge both, in a rotating order, without knowing which one is new. You get an honest verdict, better, about the same or worse, plus which earlier suggestions helped. A re-test uses one test credit like any other.

        How accurate are the AI-simulated people?

        They’re a fast first check, best at catching a confusing pitch, a price that feels too high, or a missing reason to trust you. They don’t predict real sign-ups, sales or success. Confirm big decisions with real people.

        Who can see my tests?

        Only you. Your tests, photos and reports are private to your account, and you can delete any test, or your whole account, at any time.

        How do images work?

        Images are optional. Add 1 product photo, screenshot, mockup or ad image with a 1,000-participant test, up to 3 with 10,000 and up to 5 with 100,000. The images go with every version you test. With 2 or more, every simulated person picks the one they respond to most, and your report shows the winning image, the votes for each one, which groups prefer which image and which one to use in each ad.

        Can I test the same product again?

        Yes. Open a test and press Duplicate. Everything is copied into a new test so you can change the price, the pitch or the audience and run it again.
