When you need to assess whether content may have been AI-generated, the available scanning and reporting options can shape how well a tool fits your workflow. Compare supported languages, file uploads, and batch scanning, then consider report exports for reviewing or sharing results. API access may help connect detection to other systems, while a browser extension can suit web-based checks. Free-plan availability and paid-from pricing offer additional points of comparison. AI or Not, Blackboard Learn, and Ahrefs are among the entries, alongside Facia Deepfake Detection and GPTZero. Consider which listed ways to scan and handle results matter most for your work.
