Honest about what we don't promise. Survey Validator won't guarantee your survey produces more profitable results — nobody can promise that honestly. What it does promise is cleaner data and a defensible methodology trail. The decisions you make from that data are still yours. See the FAQ.

By purchasing, you agree to our Terms of Service and Privacy Statement.

What happens after you pay

  1. Stripe processes your payment securely. We never see your card details.
  2. You'll receive a confirmation email from Stripe immediately.
  3. Within minutes, a separate email from Survey Validator arrives with your PIN and the link to the application.
  4. Use the PIN to log in. Submit your survey — that's the 1 survey your PIN grants. All re-validation, structural revisions, and wording revisions on that same survey are free. Your PIN is valid for 365 days from purchase. Want to validate another survey? Pay $39.99 again with the same email and your PIN gets another credit.

What counts as "1 survey"?

A "survey" is identified by the content of its question text. When you submit a set of questions for the first time, it counts as your 1 credit. Re-validating that same set after applying AI revisions: free. Running structural revisions on it: free. Tweaking a question and re-validating: still free if the changes are wording-only on the same items. Submitting a fundamentally different set of questions: that's a new survey, deducts 1.

We identify "same survey" by computing a content fingerprint of your question text. Question order doesn't matter; trailing whitespace doesn't matter. Adding or removing a question, or substantively rewording any item, creates a different fingerprint and counts as a new survey.

No surprise charges

Before your credit is deducted, the app shows a confirmation dialog — "You're about to use 1 of 1 credit on the survey currently in the textarea." If you mistakenly pasted the wrong survey, click Cancel, re-paste, and try again. The credit is only committed when you click Validate in that confirmation dialog. After your first successful validation, the dialog doesn't appear again (you already know the model).

Sessions and iteration budget

The app may go to sleep if you leave it idle for 15+ minutes. When you come back, log in with your PIN and re-paste the same survey — it's still recognized as your paid survey and re-validation is free. The credit is preserved.

Each PIN includes a generous AI processing budget that covers a full iteration cycle on one survey (validate → AI revision → structural revision → apply → re-validate). Most users complete their work within this budget. If you push beyond it (rare), the app pauses and asks you to buy another credit ($39.99) to continue iterating on the same survey. The exact cap is published on our Terms page so the rules are visible to anyone who wants to see them — we cap usage to keep the service sustainable for everyone, not as a hidden surprise.

Need more surveys? Same email, top-up.

If you've used your credit and want to keep going, pay $39.99 again at the same checkout link above using the same email as your original purchase. 1 more survey is added to your existing PIN automatically, within seconds — no need to re-enter the PIN. Your 365-day window also resets from the top-up date.

Easier: top up from inside the app. When you've used your surveys, the in-app banner shows a one-click Top up — $39.99 button that takes you to checkout with your email pre-filled — no chance of mistyping and accidentally creating a second PIN.

Use a different email and you'll get a brand-new PIN instead. So whichever email you used the first time, use the same one to top up.
