Description
Schema Engine AI is an AI-powered schema markup plugin for WordPress that generates valid JSON-LD based structured data, generate FAQ content from your existing pages, validates output against Google Rich Results requirements, and produces a site-wide schema audit. It is designed for editors and site owners who want clean, accurate structured data without writing JSON-LD by hand, and for SEO professionals who need a validator and a report alongside their existing workflow.
📢 Important: Review Schema is now Schema Engine AI
Same plugin, same review and rating features, plus AI-powered schema generation for articles, FAQs, products, and more. Your existing reviews and settings are preserved automatically.

The plugin supports three ways to work:
- ** Manual Mode:** Build or edit JSON-LD for any schema type with complete control over properties and nesting. Ideal for technical SEOs.
- ** Auto Mode:** Applies rule-based schema generation across post types, adapting to your content type and site structure without manual configuration.
- ** AI Mode:** Proposes a schema type and pre-fills properties from your content. Every output is checked against Schema.org and the public Google Rich Results documentation, and editors review the result before it is saved.
Why Schema Engine AI (Formerly Review Schema)
Most schema plugins ask you to fill in long forms or apply one-size-fits-all templates. Schema Engine AI lets you choose the level of automation that fits the page in front of you. A blog post can use Auto mode and a template. A complex landing page can use AI mode to draft a starting point, which you then edit. A product or local business page can use Manual mode for full control. The validator runs in the background in all three modes, so you see what is missing before you publish, not after.
- AI as a drafting tool, not an autonomous publisher. Suggestions are reviewed and edited by a human before they are saved.
- Rich results validator built in. Required and recommended properties are flagged in real time, so you see what is missing before you publish.
- Site-wide audit. One screen shows which content has valid markup, which has warnings, and which has none.
- Graph relation output. A connected @graph links Organization, WebSite, WebPage, Author, and content schemas so search engines understand entity relationships.
- SERP Preview. See how your structured data will appear as a Google search result card directly in the post editor.
- Editor-friendly. The default FAQ block renders on the front end and outputs FAQPage schema in the same step.
AI-powered Schema Markup Generator
Schema Engine AI reads your page content and generates valid JSON-LD structured data in seconds. It detects the content type — article, event, local business, FAQ, and more — then pre-fills every required and recommended property. Review, edit, and save: clean, Google-ready rich results without writing a line of JSON-LD.
Bring your own API key from OpenAI, Anthropic Claude, or Google Gemini to power the AI features — use the provider that fits your workflow and budget.
WordPress Review Plugin
Schema Engine AI is a complete WordPress review plugin for posts, pages, custom post types, and WooCommerce products. Collect single-criterion or multi-criteria ratings (quality, value, support, and more) with star or numerical scoring, pros and cons, image attachments, and GDPR consent. Aggregate ratings are output as valid structured data, so review scores can appear as star snippets in Google rich results.

Why schema markup matters for SEO, AEO, and GEO
Structured data is how search engines and AI systems read the entities, facts, and relationships on a page. It is not a direct ranking factor, but it is a prerequisite for many features that improve visibility and click-through rate.
- SEO. Pages with valid schema are eligible for Google Rich Results: review stars, FAQ dropdowns, product cards, recipe cards, breadcrumbs, and similar features. These features tend to increase click-through rate from organic search.
- AEO (Answer Engine Optimization). Featured snippets, voice assistant answers, and direct answer boxes select content that is structured, specific, and easy to extract. FAQPage and HowTo schema map directly to these surfaces.
- GEO (Generative Engine Optimization). AI search experiences such as Google AI Overviews and answer engines synthesize answers from sources they trust. Clear structured data helps these systems understand what your page is about and which claim came from where.
Data Migration
Migrate your existing structured data from the WP SEO Structured Data Schema plugin without losing a single entry. Schema Engine AI maps each schema type to its Schema Engine AI equivalent, and transfers all properties — including nested objects and custom fields — into the new format.
External services and data handling
AI Schema Generator and AI FAQ Generation send the post content you choose to process to a third-party large language model provider. The provider is the one whose API key you enter in plugin settings (OpenAI, Anthropic, or Google). No content is sent to any AI provider until you connect a key and trigger a generation. The plugin does not transmit content to RadiusTheme servers.

- Anthropic (Claude) API. Terms of Service | Privacy Policy
- Google (Gemini) API. Terms of Service | Privacy Policy
Manual and Auto modes do not contact any external service.
How AI is used in this plugin
In line with Google’s public guidance on AI-generated content, AI in Schema Engine AI is a drafting tool. The model suggests a schema type and property values; an editor reviews and edits the output; the rich results validator checks the result against Google requirements before it is written to the page. AI mode can be disabled entirely — Manual and Auto modes work without any AI provider configured.

FAQ
-
What is Schema Engine AI (formerly Review Schema)?
-
Schema Engine AI is a WordPress schema plugin that generates JSON-LD structured data, drafts FAQ content with AI FAQ generation, validates output against Google rich results requirements, and builds graph relations across your site. It supports Manual, Auto, and AI generation modes with 35+ schema types.
-
Does the plugin work without an AI API key?
-
Yes. Manual mode and Auto mode run entirely on your own server with no external calls. Only AI Schema and AI FAQ generation require an API key from a supported provider.
-
Does adding structured data directly improve Google rankings?
-
No. Google has stated that structured data is not a direct ranking factor. What JSON-LD schema does is make pages eligible for rich results and help search and AI systems understand the content, which can improve click-through rate and the chance of being cited in AI Overviews and answer engines.
-
How does AI FAQ generation work?
-
You select a page and click Generate FAQs. The plugin sends the page content to the AI provider you have configured, returns suggested questions and answers, and lets you review and edit them. When you save, the plugin writes a valid FAQPage JSON-LD block and renders the matching FAQ block on the front end.
-
What are graph relations and why do they matter?
-
Graph relations connect your structured data entities using a shared @graph array with @id references. This means your Organization, WebSite, WebPage, BreadcrumbList, and content schemas are linked together instead of being isolated. Search engines and AI systems use these connections to understand the full context of your content and entity relationships.
-
Will it conflict with Yoast SEO or Rank Math?
-
No. Schema Engine AI detects structured data produced by Yoast SEO and Rank Math, including their FAQ blocks, and skips duplicates so you do not output two competing JSON-LD blocks for the same content. You can keep using your existing SEO plugin for titles, meta descriptions, and sitemaps.
-
Does it work with WooCommerce and Easy Digital Downloads?
-
Yes. The WordPress schema plugin maps WooCommerce and EDD product fields to Product schema: name, description, image, SKU, price, currency, availability, aggregate rating, and review count. The Pro version adds Merchant Return Policy and Shipping Details, which are required for some Google Merchant features.
-
Does the plugin support Gutenberg and Elementor?
-
Yes. The Free version ships a native Gutenberg FAQ block with accordion and tab layouts, plus six Elementor review widgets. The Pro version adds Elementor FAQ widgets.
-
What schema types are supported?
-
The Free version covers Article, TechArticle, NewsArticle, BlogPosting, FAQPage, HowTo, Event, Person, Service, AboutPage, ContactPage, ProfilePage, MedicalWebPage, Movie, VideoObject, AudioObject, and place types (Mosque, Church, HinduTemple, BuddhistTemple). The Pro version adds Product, SoftwareApplication, Book, Recipe, RealEstateListing, VacationRental, Restaurant, Course, JobPosting, VehicleListing, TVSeries, PodcastEpisode, ImageObject, DiscussionForumPosting, and TaxiService.
-
What data does the plugin send to third parties?
-
Only when you trigger AI Schema or AI FAQ generation. The plugin sends the post content you selected, plus a short instruction prompt, to the AI provider whose API key you supplied. It does not send admin emails, user accounts, or settings. No data is sent on plugin activation, on every page load, or in the background.
-
Where is plugin data stored?
-
Schema configuration and per-post overrides are stored in your WordPress database in post meta and plugin options. The plugin does not store generated content on third-party servers.
-
Is the JSON-LD output editable?
-
Yes. Every property is editable in Manual mode and editable after generation in Auto and AI modes. You can also disable any field you do not want to publish.
