AI content quality & topic relevance checker
The API scores a piece of writing on quality, topic relevance, grammar, originality, readability, tone and SEO, and returns the reasons behind each score.
Editorial teams and content platforms use it as a gate before publishing rather than an audit afterwards.
AI SEO content generator — articles that rank
The API writes articles, blog posts and web copy that carry the target keywords without reading like they were stuffed in. Structure, headings and length follow what ranks for the query.
Content teams use it to produce a first draft that an editor can ship rather than rewrite.
