Schema Engine AI – AI Schema Markup, Reviews & Rich Snippets for SEO

What is Schema Engine AI?

Schema Engine AI is a structured data plugin that generates JSON-LD schema markup for WordPress sites. Developed by RadiusTheme and now five years old, it was originally known as Review Schema. The rebranding added AI-powered schema generation while preserving all existing review and rating features. With 10K+ active installs and a 4.8/5 rating from 25 reviews (92% 4% one-star), it has a strong user base. The current version is 3.0.4, last updated on Jun 22, 2026. The plugin helps editors and SEO professionals create valid rich snippets without writing JSON-LD by hand.

Schema Engine AI addresses a common problem: most schema plugins force you into rigid templates or lengthy forms. This plugin offers three distinct working modes—Manual, Auto, and AI—so you choose the level of control for each page. It validates output against Google Rich Results requirements and provides a site-wide audit. The plugin works with 35+ schema types and supports graph relation output for entity connections.

Key Features of Schema Engine AI

• Three Schema Generation Modes: Manual mode gives full JSON-LD control for technical SEOs. Auto mode applies rule-based templates across post types. AI mode reads your content and proposes schema types with pre-filled properties.
• AI-Powered Schema Markup Generator: Reads page content and generates valid JSON-LD structured data in seconds. Detects content types like article, event, local business, and FAQ, then pre-fills required properties.
• Rich Results Validator: Flags required and recommended properties in real time as you edit. You see what is missing before publishing, not after.
• Site-Wide Schema Audit: One screen shows which content has valid markup, which has warnings, and which has none. This helps you identify gaps across your entire site.
• AI FAQ Generation: Select a page and click Generate FAQs. The plugin sends content to your AI provider, returns suggested questions and answers, and writes a valid FAQPage JSON-LD block with a matching front-end FAQ block.
• Graph Relation Output: Connects Organization, WebSite, WebPage, Author, and content schemas using a shared @graph array with @id references. 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. No need to test live URLs.
• Bring Your Own AI API Key: Supports OpenAI and Anthropic C providers. Manual and Auto modes run entirely on your server with no external calls.

Who Should Use Schema Engine AI?
