AI Data Layer
AI Data Layer analyses your published content with cloud AI, builds a semantic entity graph, and exposes structured, AI-readable data describing your content and its entities — JSON-LD schema, an /llms.txt index, Markdown copies, public REST endpoints and a per-site MCP server.
What it does
- Extracts entities from your posts and pages and validates them against Wikidata.
- Generates JSON-LD schema (Article/HowTo/FAQ + entity
about[]withsameAs) and outputs it in the page<head>. - Publishes canonical entity pages at
/entities/{id}and lists them in your sitemap. - Serves an
/llms.txtindex and token-efficient Markdown copies (<permalink>.md,/llms-full.txt) purpose-built for LLM retrieval. - Exposes a public read-only REST API (
/wp-json/ai/v1/*) and a per-site Model Context Protocol (MCP) server so connected AI assistants can query your content. - Scores how interconnected your content is ("semantic cohesion") and recommends improvements, including a Topic Clusters map.
How analysis works
Analysis runs in the AI Data Layer cloud service (it is compute-intensive and is not performed on your server). When you analyse a post, the plugin sends that post's content to the service, which extracts entities and structured data and returns them for your review. You approve what gets published.
Licensing
A licence key is required to run analyses. A free trial (10 analyses) can be activated in one click from the setup screen — no card required. Paid plans and one-time credit packs are available; you manage billing through Stripe's hosted checkout and customer portal (the plugin never handles your card details).
External services
This plugin connects to external services. It is not functional without the AI Data Layer cloud service, because content analysis is performed remotely. The services below are contacted, what is sent, and when:
-
AI Data Layer cloud service (operated by the plugin author; hosted on Supabase).
- What is sent: your licence key; your site domain; and, when you analyse a post, that post's title, content and URL. Activating a trial also sends your site's admin email address.
- When: on licence validation, when you analyse a post (manually or via the optional auto-analyse setting), when you activate a trial, and when you open billing.
- Endpoint: https://oerlbhrokgkwhtzzxndw.supabase.co
- Terms: https://ai-datalayer.com/terms — Privacy: https://ai-datalayer.com/privacy
-
OpenRouter / large language model (used by the cloud service to perform extraction).
- What is sent: the post content you submit for analysis is processed by a large language model (gpt-4o-mini via OpenRouter) to extract entities and structured data.
- When: during each analysis you initiate.
- Terms: https://openrouter.ai/terms — Privacy: https://openrouter.ai/privacy
-
Wikidata (used by the cloud service to verify entities).
- What is sent: extracted entity names are checked against the public Wikidata API to confirm identifiers. No site or personal data is sent.
- When: during each analysis, after extraction.

-
Stripe (payments).
- What is sent: to start a subscription or buy credits, the plugin asks the cloud service to create a Stripe Checkout or Billing Portal session; you are then redirected to Stripe's hosted pages to enter payment details. The plugin does not collect or store card data.
- When: when you click an upgrade / buy-credits / manage-subscription action.
