Every time your URL is shared — on X, LinkedIn, Facebook, Slack, or increasingly in AI chat interfaces — the platform builds a preview card from your Open Graph tags. Missing tags mean an ugly bare link; broken ones mean a blank image and a truncated title. This tool shows you exactly what any URL's card looks like, and generates the full tag set if yours are missing.
Why it matters for AI search: OG tags are structured metadata, and like all structured metadata, they serve machines beyond their original purpose. og:title and og:description give AI systems a clean, author-controlled summary of a page, parallel to the meta description. And as AI assistants increasingly become a sharing surface themselves — answers with cited links, forwarded into chats and documents — the card those links render as is part of how your content travels.
How this tool works: in Check a URL mode, the tool fetches your page through our server-side proxy and parses every relevant tag: og:title, og:description, og:image, og:url, og:type, og:site_name, the twitter:* equivalents, plus the plain <title> and meta description as fallbacks — then renders side-by-side previews of how X, LinkedIn, and Facebook would each display the card, using each platform's fallback logic (X prefers twitter:image, others use og:image). Missing tags are flagged with a fix-it prompt. In Generate tags mode, fill in a short form and get the complete, correctly escaped tag set — both og: and twitter: variants — ready to paste into your page's <head>.
Limitations: the previews are close approximations, not pixel-perfect replicas — platforms adjust their card layouts, truncation lengths, and crop behavior without notice, so treat the preview as a correctness check (are the right tags present, does the image load, is the title sane) rather than an exact rendering. The tool reads server-rendered HTML, so OG tags injected client-side by JavaScript won't be detected — which is also true for most social platform crawlers, making that a genuine problem worth fixing rather than a tool limitation. Platform-specific extras (like og:video or product cards) aren't currently generated.
