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.
See his work →“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.”
Arthur Andreasyan
Founder, Puffy
“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.”
Carlos Arias
Founder, Medellin
“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
Ask a general model to review a screen and you get an opinion. ProUX measures: contrast ratios, tap target sizes, text sizes, computed from the actual pixels. Every finding cites a verified guideline by number, so you can check the claim rather than trust it.
100,000 tokens a month, the free half of the UX library, and real audits. Enough to see whether the findings are useful before you pay anything.
The same product. Quarterly costs more per month because less commitment costs more. Yearly is 42% cheaper and renews automatically until you turn it off.
Nothing breaks. You can see what is left as you go, and a pack tops you up any time. Packs never expire and are only used after your monthly allowance.
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.
Extra tokens when you need more than your plan allows, without moving up a plan. Buy once, never expires.
No. Every finding 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. The models are the least interesting part: what makes the answers different is the verified guideline library and the methodology behind them.
