About
Your instant principal UX expert
Principal-level review of design, code, and growth used to be scarce and expensive. UXexpert.ai makes it instant, private by default, and honest — with a human always in the loop.
Why we built it
A truly senior review — someone who can look at a product and see the usability gaps, the fragile code, and the leaks in the funnel all at once — is one of the scarcest things in software. Most teams get it rarely, late, or never. And most tools only check one dimension: Lighthouse for performance, an axe scan for accessibility, a separate pass for conversion.
Modern AI models can now reason across all three at once, reading real code and real screenshots in context. UXexpert.ai turns that into a review anyone can run in minutes — on a live URL, a GitHub repo, pasted code, or a screenshot — and get back prioritized, code-native fixes instead of a vague grade.
How it works
Every audit runs three lenses at the same time and returns findings scored by severity, effort, and impact — each with a concrete fix, often a snippet you can paste straight in.
A principal UX review of usability, hierarchy, and accessibility mapped to WCAG.
A full-stack code audit of quality, correctness, and performance signals.
A strategist's read on conversion, clarity, and the paths users actually take.
You choose the engine. The local engine runs entirely in your browser — nothing leaves your device. The optional Claude AI engine adds deeper reasoning using your own Anthropic API key, sent directly from your browser to Anthropic. And you can tune any audit to your real users by uploading expertise skills — domain packs that make the review an expert in your product's world, not a generic checklist.
What we believe
Private by default
The local engine never sends your code anywhere. The AI path goes straight from your browser to Anthropic with your own key — we have no server in the middle and never see your code or your key.
Honest, not inflated
No invented testimonials, no fake user counts, no "trusted by thousands." The product earns trust by being useful and by telling you plainly what it is — an assistant, not an oracle.
Fixes, not just findings
A grade you can't act on is noise. Every finding is prioritized and paired with a specific, concrete fix, so the report turns directly into a backlog you can ship.
A human in the loop
UXexpert produces automated and AI-assisted suggestions — powerful, and sometimes wrong. It is not professional advice and passing an audit does not certify compliance with WCAG or any law. Treat every finding, user story, and fix as a strong first draft: a person should review, validate, and edit it before acting. That principle is built into the product on purpose, and you'll see it stated throughout.
Who's behind it
UXexpert.ai is operated by TnTW LLC, a Wyoming (USA) limited liability company. It's an independent, bootstrapped product in active development — funded directly by the people who use it, through Pro subscriptions, rather than by advertising or reselling your data. That's deliberate: the incentive is to make the audits better, not to monetize what you put into them.
