Questions, answered

  • About 15 questions a month, or 3 screen reviews. The 50 free guidelines open in full, and every answer cites the guideline it stands on. No card needed. Enough to judge it before you pay anything.

  • A general model answers from memory and gives you an opinion. ProUX answers from a verified library of UX laws and guidelines and cites the one it used, so you can check the claim rather than trust it. On a screen review it also measures the real pixels: contrast, tap targets, text sizes.

  • In tokens, the units the models bill in. A question uses a few thousand, a screen review more. Free includes 100,000 a month, about 15 questions or 3 screen reviews. Pro includes 1.9 million, about 215 questions or 70 screen reviews. You can see what is left as you go.

  • The same product. Quarterly costs more per month because less commitment costs more. Yearly is 42% cheaper. Both renew automatically until you turn them off.

  • In US dollars by card, or in rupees with UPI Autopay, cards and netbanking. Rupee prices add 18% GST, shown before you pay. Switch the currency at the top of the pricing page.

  • Nothing breaks. You can see what is left as you go, and you can top up from inside the app any time.

  • Any time, from Settings. Your plan runs to the end of the term you paid for.

  • Full refund within 5 days of your first purchase. No questions.

  • No. Every answer says what is wrong, why it matters, and what to change. If you want the reasoning, it is cited and you can read the guideline it came from.

  • Claude, Gemini and GPT, chosen per task. Free runs on the quick models, Pro on every model. The models are the least interesting part: what makes the answers different is the verified guideline library and the methodology behind them.
