AI design critique: reviews that push back

Tipalti's own user personas critique a screen and argue with each other about it, before the real design review does. Designed and built solo on the Claude API.

Timeline
July – October 2026
The tool's home screen: the headline Design reviews that push back, and a numbered list of three modes: Adversarial critique panel, Usability expert review and Accessibility review.
The problem

One screen. Very different readers.

A CFO, an AP specialist, a monthly approver and an external vendor all use the same Tipalti screens, with very different goals. Design reviews catch usability issues but miss what matters to each of them.

And more non-designers now build UI without any design review.

What I did

Solo · concept to working tool

Turned our persona research into AI reviewers, designed how they rank, debate and reach a verdict, and built the tool. Designers use it as a pre-review check. Non-designers building UI use it to get critique on their own.

Step 04 · Argue back

Push back on any finding

Pin a comment and argue back. The persona concedes when you're right.

A Controller / Treasurer finding card with three points: an approval issue, a mobile issue and what works. A comment pin on the mobile point opens a thread where the designer replies that the form stacks to one column below 640px, and the persona takes the point back.

Why I built it

A side project that took off

I built this for myself, out of curiosity: to see what my idea could become with AI's help. When I showed it to colleagues, it got far more interest than I expected.
