Is My Landing Page Valid? is an AI conversion audit for landing pages. Paste a URL (or a screenshot) and in about 20 seconds you get a 0-100 conversion-readiness score graded on a fixed rubric, your single biggest leak free, and on unlock: every leak ranked by severity, a concrete fix for each, and an AI-rebuilt version of your page. Built for founders, indie hackers and marketers who get traffic but few signups. It runs on Claude, it never invents fake social proof, and it is blunt on purpose. Free to run, one-time unlock at $2.90, or Pro for auditing pages every week.
