Paste a URL — a video page works best — and Lens scores it three ways: classic SEO (rich-result readiness), AEO (how citable it is to answer engines like ChatGPT, Claude, Perplexity), and caption quality straight from the captions. Every miss comes with the fix.
Reads the public page only — never logs in, never stores your URL. Captions are graded from the page's own caption track / transcript.
