Your interface deserves a second opinion.
I built this to catch the design problems people notice—but rarely know how to explain.
Chrome extension only.
Why I made this
I’m a designer who got tired of shipping “AI-generic” designs. The real problems aren’t always obvious, and most feedback is either too vague or too late.
Everybody is vibecoding now. Why does everything have to look the same? We can ship fast and still ship amazing, premium-looking products.
ReadPenn gives you clear, actionable feedback—right in the browser—so you can fix what matters before your users do.
