Copyleaks AI Detector

What it does

Copyleaks AI Detector is a text and image scanning application that checks content for likely AI generation and plagiarism. Text AI detection covers 30+ languages and plagiarism detection covers 100+ languages. A single report combines both checks, and the explainable AI Logic feature accompanies the results.

Several files can be uploaded in one scan. The browser extension works in Chrome, Edge, and Firefox, and a Google Docs add-on scans from inside a document. Scans can be saved to an account for later review. Credits are unified across words and images, and the Pro plan adds sitemap-based website scanning, cross-language detection, advanced filters, and an analytics dashboard.

Personal and Pro are subscriptions billed monthly or annually, and new users receive limited free credits to try the tools. Education and enterprise needs such as API access and LMS integration go through sales for custom pricing. Detection results are probabilistic indications, not proof of authorship.
