I think 383toast is talking about your landing page design which has very strong AI-generated design vibes (blue-green gradients, rounded rectangles with a colored border on the left...) There are a bunch of skills you can find online to improve on this if you want to keep designing with Claude, and the latest generation of models are better (Fable/GPT5.6).
Check https://github.com/jakubkrehel/skills or https://github.com/emilkowalski/skills (more around animations), maybe https://github.com/leonxlnx/taste-skill (didn't try it)
I got the same vibes. I really wish YCombinator would mentor startups on design. Unfortunately, most of the landing pages in their startup directory look like raw AI designs.
I'll check them out, thank you for your suggestions!
