01 · The problem

Your AI grades its own homework.

Your AI reviews its work with the same eyes that made the mistakes. It doesn't hesitate at a sign-up form the way a human does. The blind spots survive because you're too close to your product, and so is the model that built it.

02 · The process

Zero effort on your side.

Send your link

A live URL or staging access, plus a line about who your users are. Any other helpful information is welcomed.

The audit

A human designer evaluates your product, testing usability, clarity, and marking every point of friction.

The report

A report of findings ranked by impact: top fixes, unclear copy, missing states. Each fix written as a prompt your AI tool can run.

03 · The method

A structured evaluation. Not vibes.

The framework behind €6,000 agency audits, applied by a human designer (not AI) with a fixed scope.

01 · Heuristics

Nielsen's 10 usability heuristics

Every screen scored against the industry-standard usability framework: consistency, feedback, error prevention, user control.

02 · Flows

Conversion path analysis

Landing, sign-up, first value, return. Every step where users leak, mapped end to end.

03 · Trust

Content & credibility review

Messaging, hierarchy, proof and pricing clarity. The words and signals that decide whether visitors believe you.

04 · Access

Accessibility & responsiveness

Contrast, touch targets, keyboard paths, breakpoints. The failures AI tools produce most and founders see least.

05 · Consistency

Design consistency & drift

Every regenerated screen shifts spacing, buttons and hierarchy. Trust erodes quietly.

04 · The deliverable

Every issue looks like this.

Severity-rated, annotated, ordered by impact against effort. A fix list your AI tool or your developer can execute. Not a lecture.

For reference: agency UX audits run €3,000 to €10,000+ over three to four weeks, and the new AI-code audit shops charge €1,500 to €7,500. This ladder sits under both on purpose.

06 · Fit

Built for people shipping fast.

07 · Queries

Straight answers.

Does it matter which tool built my app?

No. Lovable, Bolt, v0, Figma Make, cursor-built: the audit reviews what users experience, not the code. Fixes are written so you can paste them back into your tool as prompts, or hand them to a developer.

Why not just ask ChatGPT to review my UI?

You could. An LLM recites general best practices. The audit finds the issues specific to your product, ranked by what to fix first, from a human designer who has shipped products for over a decade.

My product hasn't launched yet. Worth auditing?

More so. Fixing UX before launch is the cheapest it will ever be. Staging links and prototypes are fine for the audit.

What if the audit finds nothing useful?

If a Pro or Max report doesn't give you at least 10 actionable findings, full refund.

How is this different from usability testing?

Usability testing watches real users attempt tasks. Done well it takes weeks: recruiting, sessions, analysis. An audit is an expert review, one human designer against a structured method, done in days. It catches the failure patterns designers know on sight and everyone else misses, so if you run testing later, you're testing a product that isn't leaking in obvious places. No panels, no recruiting, no handoffs.

What do you need from me to start?

Every audit starts with the free call. Then: a link to your product (live, staging, or prototype) and a line about who your users are. Payment starts the clock.

Is my product kept confidential?

Yes. Your product, staging links and report stay private. Nothing is shared or used as a case study without written permission.
