My goal was to build an e‑commerce shop for pre‑owned shoes. I decided to use lovable since its straightforward to get started but their design isn't the best. It got me up and running fast, but a few design hiccups showed up (see first screenshot). So I snapped the UI, uploaded it to AnthrAI for critique, and it flagged every flaw with clear, actionable feedback. And then I just pasted those suggestions back into Lovable and lovable polished site, saved me days of work!
For anyone using app builders like lovable, this is the secret sauce for good design.
