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.
Product content writer — SEO-friendly descriptions
Product copy generated per listing, optimised for search engines without reading like keyword filler. Electronics, fashion and home goods each get an appropriate voice.
Stores use it to fill a catalogue that would otherwise stay on manufacturer boilerplate.
