- Detects AI-generated text, source code, and plagiarism, and (since June 2026) AI-generated video and audio via a dedicated AI Video Detector that performs simultaneous, independent scans of a video file's visual and audio tracks to identify the exact moments AI-generated content appears. Targets academic institutions, enterprises, and SEO professionals, with the video detector aimed additionally at KYC, refund-fraud, and insurance-claims use cases.
- distinctFrom
- One of the few major detectors that extends its capabilities beyond text to explicitly scan programming code and integrate deeply with LMS platforms.
- notes
- Claims over 99% accuracy. Generally maintains a low false-positive rate on raw AI output, but effectiveness declines significantly with manual humanizing. Launched an AI Video Detector on June 2, 2026 (enterprise-grade, frame-level scanning of video and audio tracks independently, flagging fully synthetic content, AI speech paired with real footage, and hybrid AI-altered splices), materially extending Copyleaks beyond its original text/code/plagiarism scope; predates this lens's 2026-07-27 window but not previously reflected in this entry.
