Detect.ai
Detect.ai is an AI detection and humanization platform for writers, educators, and publishers who need to check whether text was machine-generated and rewrite flagged passages in one place. You paste or upload content, get a detection score with section-level notes, then run the humanizer to rework AI-sounding lines without leaving the app.
Most AI detectors stop at a yes-or-no score. Detect.ai pairs detection with rewriting and a small suite of free writing utilities (paraphraser, grammar checker, summarizer), so teams can audit drafts and fix them in the same session instead of bouncing between a scanner and a separate rewriter.
It fits content editors vetting client copy, university staff reviewing student submissions, SEO teams checking outsourced articles, and freelancers who want a single workflow before publishing. iOS and Android apps mirror the web tools for on-the-go checks.
