ShitFast▲14A passion project I started recently. Please submit your own (or any) website you suspect might score high as "AI-slop" and we'll publish a roast soon. Note that my goal is two-fold: I'll use (most) submitted websites in some research I'm going to be publishing later. Thanks!

I built a tool to roast landing pages with AI agents. I was gathering feedback from watching landing page roast videos, and figured out I could prompt LLMs to analyse a screenshot and roast based on the same criteria. It's not 100% accurate yet, but it has been really insightful when I've tested it on my own websites. Let me know what you think!
