Top comment

Many UI issues I’ve seen aren’t visual problems but unchecked assumptions about users.

The tool takes a UI screenshot and makes those assumptions explicit, along with the risk of being wrong.

This isn’t meant to replace user testing. It’s a pre-mortem to catch risky assumptions before you invest in proper testing. Curious where people think this breaks down or gives false confidence.

Comment highlights

Great UX audit product, I think it will help a lot of people building by themselves or people who are not from the design field uncover these assumptions. 🥳

I feel you could add the wins also, they might trigger more thoughts on how to fix it.


All in all, had a good time trying this as my design partner. ✌️
