Check your landing page copy in 60 seconds

An automated checker for the words on your page — not the pixels. 16 checks across Clarity and Trust run instantly against your live URL, and every finding cites the research behind it.

A checker, not a checklist.

60 seconds, not a 60-minute teardown

Paste a URL, get a scored report. No discovery call, no "book a demo", no PDF that arrives next Tuesday. The checker fetches your live page and runs while you watch.

Median run: ~60s

16 automated checks, free

The free check runs the Clarity and Trust lenses: single dominant H1, jargon in the hero, testimonial quality, proof near claims, and 12 more. The full report runs all 55 checks across 9 lenses.

Every flag cites its source

This isn't a linter of one developer's opinions. Each check traces to Ogilvy, Cialdini, Schwartz, or published CXL Institute research — so you can verify the rule before you rewrite anything.
