Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

SUBJCT is a content optimisation platform for publishers, brands, marketing teams and AI-search specialists. It analyzes content archives, maps entities, creates internal links, generates JSON-LD schema, applies automated entity tags and identifies topical-authority gaps. Its web application and API are designed for teams that want to structure existing content for AI search engines and semantic search systems, rather than for teams seeking a broad, general-purpose content suite.

Pricing is plan-based. Starter costs £199 per month and includes automated internal semantic linking, automated anchor text selection, schema markup and JSON-LD, automated entity tagging, an entity analysis dashboard and automated content recommendations. Pro costs £499 per month and lists the same highlights. Enterprise adds bespoke AI-powered content solutions, strategy sessions, dedicated onboarding and team support. The published plans show a paid product with no free plan, so SUBJCT is better suited to teams with a defined content-structure budget than to buyers looking for a low-cost way to explore content optimisation.

Its strongest fit is a technical workflow around entities and semantic relationships. SUBJCT covers entity analysis across content archives, Google Knowledge Graph linking, competitor topical-authority gap analysis and prompt optimisation in the editor. WordPress integration, an API and an MCP server support different publishing and automation setups, while entity-aware JSON-LD generation addresses structured content directly. Choose SUBJCT when internal linking, entity tagging, schema and topical gaps are central requirements. Choose an alternative when you need broader content optimisation coverage, a free entry tier or more differentiated features between the lower paid plans.
