An AI schema generator that only uses facts from your page
Structured data must describe what is actually on the page — Google ignores, and can act against, markup that claims ratings, prices or dates the visitor can’t see. That makes “let the AI write my schema” risky: language models happily add a brand, a cuisine or a 4.8-star rating. This AI schema generator is built the other way round. Paste the page’s text or HTML (or fetch a web address), and rules first decide what the page is — a recipe, a product, an event, a job posting — and read every property they can find.
The AI, running on your device, then fills the gaps as JSON. Each value it suggests is checked against the page: a name, date, number or URL that does not appear there is removed and listed in red, so the JSON-LD you copy contains only facts from the source. The result is validated against Google’s required and recommended properties for eleven types, with an honest note on which still earn rich results in October 2026.
Without AI you still get the rule-based JSON-LD. For hand-editing every field, use the Schema Markup Generator; to see what a live page already declares, the Meta Tag Analyzer.
How to generate JSON-LD from a page
- Choose Paste text or HTML and paste the page source (or its text), adding the Page address so images and links become absolute — or choose Web address and press Fetch page.
- Leave Schema type on “Detect from the page”, or pick a type yourself. The line under it says what was detected and why, and whether the page already has JSON-LD.
- Press Fill gaps with AI (the page asks before any model download) or Rules only.
- Read the notes: red for required properties that are missing or AI additions that were removed, amber for recommended ones.
- Copy the script tag (the copy button includes
<script type="application/ld+json">), paste it into the page, and confirm with Google’s Rich Results Test.
AI Schema Generator features
Type detection by rules
Prices and “Add to cart” → Product; ingredients and method → Recipe; date, time and venue → Event; address with opening hours → LocalBusiness; hiring words and salary → JobPosting; plus Course, SoftwareApplication, VideoObject, Article, Organization and breadcrumbs.
Facts read from the page
Dates become ISO 8601, “Prep time: 5 minutes” becomes PT5M, “₹6–8 LPA” becomes a yearly salary range in INR, “Mon–Sat 8 am – 10 pm” becomes opening-hours specifications.
AI additions fact-checked
Strings, numbers, dates and URLs suggested by the AI are kept only if they appear in the page; everything else is removed and named.
Google’s checklist
Required and recommended properties per Google Search Central, merchant-listing needs for products, breadcrumb URLs, and a time-zone reminder for event times.
Safe to paste
“</script>” inside text is escaped so the tag cannot break your page. Fetched HTML is parsed as data; its scripts never run.
Worked example: a masala chai recipe page
The sample page has a breadcrumb trail, a title, a byline with a date, a description, a photo, “Prep time: 5 minutes · Cook time: 10 minutes · Serves 2”, six ingredients and four steps. Rules detect Recipe (ingredients list, method steps, kitchen quantities, prep/cook time) and BreadcrumbList, and produce a Recipe with name, image, author Priya Raman, datePublished 2026-10-02, prepTime PT5M, cookTime PT10M, totalTime PT15M (“ready in 15 minutes”), recipeYield 2, the ingredients and HowToStep instructions. Both required properties are present; recipeCategory, recipeCuisine, keywords, nutrition.calories and video are listed as recommended but missing.
When the AI suggests recipeCuisine “Indian”, recipeCategory “Beverage”, keywords “masala chai, spiced tea” and 120 calories, only the keywords survive — the other three are not on the page, so they are removed and named. Add them to the page first if they are true.
Which types still earn rich results (checked 14 October 2026)
| Type | Required by Google | In Search today |
|---|---|---|
| Article | None (headline, image, dates, author recommended) | Article rich results |
| Product | name + offers, review or aggregateRating; merchant listings also image, price, currency | Product snippets, merchant listings |
| Recipe | name, image | Recipe rich results and carousels |
| Event | name, startDate, location with name and address | Event experience |
| LocalBusiness | name, address | Business details (with your Business Profile) |
| JobPosting | title, description, datePosted, hiringOrganization, jobLocation (or remote with applicant location) | Job search experience |
| SoftwareApplication | name, offers.price, aggregateRating or review | Software app rich results |
| VideoObject | name, thumbnailUrl, uploadDate | Video results, key moments |
| BreadcrumbList | itemListElement with name, position, item | Breadcrumb trail on desktop |
| Course | name, description | Course info phased out in 2025; course list carousel needs 3+ courses |
| Organization | None | No rich result; logo and knowledge panel |
Sources and limits
- Property lists follow Google Search Central’s structured-data pages (most last updated 8 September 2026; VideoObject 24 September 2026) and its search gallery (15 June 2026). Google announced the end of Course info and six other features on 12 June 2025; FAQ rich results ended for all sites on 7 May 2026 and HowTo in 2023, so this page does not offer them — the AI FAQ Generator still writes FAQPage markup.
- Rules read common layouts, not every theme: check that names and addresses came out whole. Event times have no time zone unless the page states one — add the offset yourself.
- Fetching uses this site’s page fetcher without cookies, so pages behind a login or built entirely by scripts may come back empty; paste their HTML instead.
AI Schema Generator FAQ
Is this AI schema generator free and private?
Yes. Pasted text and HTML are read in your browser and the AI runs on your device. Only “Fetch page” sends the address you typed to this site’s fetcher, and only when you press it.
Will the AI invent a rating or a price?
It may suggest one, but the page removes any value it cannot find in your source and lists it in red. Markup must match what visitors can see, so add facts to the page before adding them to the schema.
Which schema type should my page use?
The one that matches the main thing the page is about: a single recipe, product, event, job or business. Breadcrumbs can be added to almost any page. The detector explains its choice; you can override it.
Does structured data improve rankings?
Not directly — Google says it helps it understand the page and makes it eligible for rich results. Eligible does not mean guaranteed; Google decides when to show them.
How do I test the JSON-LD?
Paste the script tag into the page’s HTML, publish it, and run the URL through Google’s Rich Results Test or the Schema Markup Validator; Search Console reports problems over time.
