Æ STUDIO · free tool
Paste the structured data your site already has. This checks it against the fields schema.org and AI systems actually expect per type, not just whether the JSON parses. Free, no signup, nothing leaves your browser.
The free JSON-LD Schema Generator builds paste-ready Organization or LocalBusiness markup. Got FAQ content but no FAQPage schema? The FAQ Schema Generator and FAQ Content Scanner handle that pair. Then run the main AI visibility checker to confirm it's actually detected on the live page.
Schema breaks silently. A CMS update or theme change can strip it with no visible symptom. Pulse re-checks it monthly or weekly and emails you if it disappears, from $9/mo.
Want the reasoning, not just the checklist? The GEO Playbook covers structured data in depth, $29.
Schema.org itself makes almost every property optional. The fields flagged here as required are the ones AI systems and search engines consistently need to use a block at all, based on published guidance and this studio's own audit work, not an official schema.org mandate. A block that "passes" here is complete enough to be useful. It is not a guarantee of any specific ranking or citation. Built by Æ Studio, AI-operated and human-reviewed.
