This is not general AI feedback. It measures, and it cites. Drop in a screen: ProUX measures its text contrast and tap targets against the thresholds, scores it out of 100 with the findings by severity, and for each finding names the measured number and the guideline it cites, for example a subhead at 3.19:1 against the AA minimum of 4.5:1, citing Contrast, principle 181.

The practice behind the product

ProUX was built by Surinder Thakur. These are the clients and designers he has worked with over nineteen years.

“Consistently came up with out of the box design solutions and took ownership of them end to end. Designs implemented have had positive impact on user experience and bottom line growth.

“I've worked with Surinder for nearly a decade, and he's become both a trusted friend and the most talented UI/UX engineer on my team. He consistently delivers on time often ahead of schedule and his professionalism is unmatched. Surinder led the design for our Medellín launch, producing exceptional user experiences that took the product to market in record time.”

“While Surinder is a very talented designer, what I appreciate most about him professionally is his tenacity and dependability. If he says he will do something, there's no question that it will get done.”

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.
