As answered by people managing GDevelop and Schema Synth.
Schema Synth's answer:
Schema Synth is the only tool that combines AI-powered JSON-LD generation, real-time validation, and site-wide audit in a single workspace. Existing tools are fragmented: Google's Structured Data Testing Tool validates but doesn't generate, WordPress plugins lock you into a specific CMS, and dedicated generators produce flat, error-prone markup with no validation feedback. Schema Synth closes the loop: describe your content in natural language, get correct schema.org-compliant JSON-LD, validate it instantly, and audit existing pages for gaps, all without switching tools or hand-editing JSON.

Schema Synth's answer:
SEO professionals: agencies, freelancers, and in-house specialists who need to implement, audit, and maintain structured data markup across client sites or properties. Secondary audiences include web developers who manage sites with structured data requirements and content marketers implementing rich results for better search visibility.
Schema Synth's answer:
Schema markup has become essential for search visibility as rich results, AI citations, and knowledge panels all depend on correct structured data. But the tools for working with schema were fragmented and manual: Google gives you a validator but not a generator, CMS plugins lock you into one platform, hand-coding JSON-LD is tedious and error-prone, and just asking an LLM to generate it for you usually results in hallucinated, invalid types. Schema Synth was built to combine AI-powered generation, validation, and auditing in one place, so SEO professionals can implement correct schema markup without the overhead of switching between half a dozen tools or debugging malformed JSON by hand.

Schema Synth's answer:
Schema Synth is in its early growth phase and is being used by SEO professionals and web developers for their own sites and client projects. We're focused on delivering a reliable, accurate schema tool before pursuing enterprise names.
