AI website design checker — UI & UX analysis
The API scores a website's interface on usability, accessibility, navigation and performance, and returns the specific changes that would raise each score.
Designers and agencies use it to turn a subjective review into a report a client can read.
SEO Master Scan — website analysis & performance reporting
The API crawls a site and returns an SEO report: what is broken, how the site performs and which fixes move the ranking. Recommendations are specific rather than generic advice.
Agencies and site builders use it to produce a client-ready audit without running their own crawler.
