The Landing Page Test
One product brief. Two models asked to build a complete, styled landing page — hero, features, CTA, the works. Fully interactive. No frameworks.

The exact prompt we used
prompt.txt — fed identically to both models
Build a complete, styled, single-file HTML landing page for a fictional AI writing tool called "Draftly." Include: hero section with headline and CTA, 3-feature grid, one testimonial, email signup form. Make it look genuinely professional — good typography, real color palette, proper spacing. No frameworks, no external fonts, no JS libraries. All styling inline or in a style block. Must work as a raw HTML file.
Don’t take our word for it. Paste this into any AI model and compare your result against the outputs below.
