From the developer

RadiusTheme's own description of Schema Engine AI, lightly tidied.

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.
