FAQ
Does Landing Page Lie Detector use AI?
No. It uses local rules to flag risky claim patterns, proof gaps, vague wording, and urgency language in your browser.
Can it prove that a landing page is truthful?
No. It highlights copy that deserves review. You still need to add real evidence, context, and human judgment.
What should I do after a line is flagged?
Either add proof near the claim, narrow the promise, remove fake urgency, or rewrite the line so it says exactly what you can support.
