What AI Detector Pro is
AI Detector Pro is a web tool for identifying signs of AI writing in documents and revising text. For English documents, it highlights passages likely to trigger AI detectors and shows predicted text and overused AI phrases. The product lists detection for English, Spanish, French, Arabic, German, Korean, and Portuguese writing. AI Eraser proposes English wording changes, with control over how much the text changes. Tone analysis, phraseology, and a pinpoint editor are also included. The Free plan provides three AI scans per month and no humanizations. Basic and Unlimited plans list Word and Google Docs plugins, multilingual detection, tone analysis, and the pinpoint editor; Basic allows 103 scans monthly, while Unlimited has unlimited scans. API access requires an eligible subscription, and report requests cost $0.09 per unit of up to 4,000 characters; other endpoints are free. The company says user text may be shared with third-party AI models for core functionality and cautions that identifications and revisions can be incorrect.
