I built an AI landing page roaster in a weekend using Claude API + Netlify Functions

Every time I shared a landing page for feedback, I got the same useless responses: "Your headline could be clearer" "Add more social proof" "The CTA isn't strong enough" Great. But which headline? What kind of social proof? How do I fix the CTA? Vague feedback doesn't convert visitors into customers. Specific feedback does.
