Site scanner
Crawl what an agent can read today: pages, entities, existing schema, and the gaps between them.
Features
Everything you need to ship schema, and keep it shipping.
SchemaX is the whole pipeline. Scan, propose, review, deploy, verify. Built so a single product person can ship, and a hundred-person team can govern.
Schema studio
Visual editor for every field of every entity. Diff before you ship.
Evidence-backed AI
Suggestions carry the page snippet they're drawn from. Grounded facts publish automatically; uncertain ones wait for you.
One-snippet deploy
A single script tag publishes approved schema without a rebuild or CMS migration.
Live verification
Published schema is checked against the live page so stale or unsupported fields are flagged.
Drift detection
When content changes and schema no longer matches, you find out before the mismatch compounds.
Versioning + rollback
Every change is a version. Roll back in one click. Audit trail forever.
Workspace dashboard
See page status, approvals, published versions, and drift alerts from one operational view.
Export paths
Use the managed injector, GTM export, or developer-ready schema output when your stack needs it.
Why grounded schema
Four public-page snapshots. Audited against what is actually on screen.
These examples show the gap between page content and machine-readable markup: values stated incorrectly, visible facts omitted, and the grounded schema SchemaX is built to publish instead. No invented prices. No borrowed facts.

A recipe snapshot with a 1000x nutrition mismatch and a visible rating left out of markup.
BBC Good Food/bbcgoodfood.com/recipes/easy-pancakes
Published snapshot
The markup snapshot restates salt as sodium, a different nutrient, with a 1000x unit error. The visible rating is not declared.
{
"@type": "Recipe",
"name": "Easy pancakes",
"nutrition": {
"@type": "NutritionInformation",
"sodiumContent": "0.1 milligram of sodium"
}
// no aggregateRating
// no fiberContent / servingSize
}Grounded output
We keep the salt figure verbatim, drop the fabricated sodium, and add the rating that was visible all along.
{
"@type": "Recipe",
"name": "Easy pancakes",
"aggregateRating": {
"@type": "AggregateRating",
"ratingValue": "4.1",
"ratingCount": "876"
},
"nutrition": {
"@type": "NutritionInformation",
"fiberContent": "0 g",
"servingSize": "per pancake"
}
}On the page
- Nutrition table: salt 0.1 g, not sodium
- Rating block: 4.1 stars from 876 ratings
- Method steps with exact quantities
What you’d gain
Recover eligibility signals for the rating that was on the page but absent from the machine layer.
A product page with zero structured data about the product.
Open Food Facts / Nutella/world.openfoodfacts.org/product/.../nutella-ferrero
Published snapshot
The JSON-LD snapshot describes the website itself. Nothing tells an agent what the product is, despite a full fact sheet on screen.
{
"@type": "WebSite",
"name": "Open Food Facts",
"url": "https://world.openfoodfacts.org"
// describes the site, not Nutella
// no Product node at all
// no gtin / brand / nutrition
}Grounded output
We build the Product that was missing, with every field grounded against the visible fact sheet.
{
"@type": "Product",
"name": "Nutella",
"gtin13": "3017620422003",
"brand": { "@type": "Brand", "name": "Nutella" },
"manufacturer": "Ferrero France Commerciale",
"additionalProperty": [
{ "name": "Nutri-Score", "value": "E" },
{ "name": "NOVA group", "value": "4" }
]
}On the page
- Barcode (GTIN-13) and producer: Ferrero France Commerciale
- Nutri-Score E / NOVA group 4 (ultra-processed)
- Ingredients, allergens, per-100 g nutrition
What you’d gain
Make the product itself machine-readable, not just the website around it.
Correct as far as it goes, but under-typed for an opinion column and missing the standfirst.
The Guardian/theguardian.com/.../brexit-bus-economy-vote
Published snapshot
The Guardian's markup is accurate, but it types an opinion piece as a generic NewsArticle and omits the description, section, and author's role that are all right there.
{
"@type": "NewsArticle",
"headline": "The Brexit bus...",
"author": { "@type": "Person", "name": "..." },
"datePublished": "2024-..."
// no description (standfirst)
// no articleSection: Opinion
// no author jobTitle / inLanguage
}Grounded output
We promote it to the specific type, fold the standfirst into a description, and add the section, language, and the author's stated role.
{
"@type": "OpinionNewsArticle",
"headline": "The Brexit bus...",
"description": "<standfirst, verbatim>",
"articleSection": "Opinion",
"inLanguage": "en-GB",
"author": {
"@type": "Person", "name": "...",
"jobTitle": "Guardian columnist"
}
}On the page
- URL path /commentisfree/ and section label Opinion
- Standfirst paragraph below the headline
- Byline: Guardian columnist
What you’d gain
Let an agent read the page as opinion, in English, by a named columnist, not as anonymous generic news.
A product page where the service is invisible and the tempting autofill would invent a price list.
Cloudflare CDN/cloudflare.com/products/cdn/
Published snapshot
The markup snapshot contains Organization, WebSite, and WebPage nodes. Nothing describes the CDN service. A naive generator could invent plan tiers that do not appear on this page.
{
"@type": "WebPage",
"name": "Cloudflare CDN",
"isPartOf": { "@type": "WebSite", "...": "..." }
// no Service node for the CDN itself
// no serviceType / provider / areaServed
// tempting autofill: hasOfferCatalog
// [Free, Pro, Business, Enterprise] - not on page
}Grounded output
We emit the Service that anchors the page, keep only grounded properties, and refuse the price tiers that are not on it.
{
"@type": "Service",
"serviceType": "Content Delivery Network",
"provider": { "@type": "Organization", "name": "Cloudflare" },
"areaServed": "Worldwide",
"offers": {
"@type": "Offer", "price": "0",
"url": "https://dash.cloudflare.com/sign-up"
}
// no invented tier catalog
}On the page
- Content Delivery Network across 330+ cities worldwide
- Start building for free points to dash.cloudflare.com/sign-up
- Links to WAF, DDoS, Workers, Load Balancing
What you’d gain
Make the service machine-readable without publishing a price list the page never claimed.
Policy-first
You set the rules. SchemaX does the rest, and shows you every exception.
Generative tools that just push raw schema make a mess. SchemaX runs deterministic extraction first, auto-publishes only what it can ground, and surfaces the uncertain or sensitive claims for you. AI commits the safe 80%; you decide the rest, and you can pause everything.
- Diff every change against last published
- Inline evidence: “this came from this paragraph”
- Review only the exceptions: accept, edit, or reject
- Roll back instantly when a vendor breaks something
