Show HN: Instantly surface the assumptions behind a UI screenshot

https://app.usercall.co/ai-user-testing
3•junetic•1h ago
Many UI issues I’ve seen aren’t visual problems but unchecked assumptions about users.

I built a small tool that takes a UI screenshot and makes those assumptions explicit, along with the risk of being wrong.

It’s meant as a quick design pre-mortem or critique before shipping.

Would love feedback on whether this way of critiquing UI is actually useful.

Providing some sample screenshot+output pairs would be helpful and probably singificantly increase the odds users interact with your product.
