What Copyleaks does
Copyleaks is a content integrity platform that checks text for AI generation and plagiarism, and also scans images for signs of AI. According to its pricing page, a text scan produces one report covering both AI and plagiarism, while image scanning covers AI only. AI detection works in 30+ languages and plagiarism detection in 100+ languages.
Two self-serve subscriptions are listed. Personal costs $16.99 per month billed monthly or $13.99 per month billed yearly. Pro costs $99.99 per month billed monthly or $74.99 per month billed yearly, and adds 25 user seats, sitemap-based website scanning, detection of plagiarism translated from other languages and an analytics dashboard. Usage is measured in credits, and 1 credit covers up to 250 words or 1 image.
Both plans list a browser extension for Chrome, Edge and Firefox, a Google Docs add-on and MCP access for running scans from Claude and other AI tools. Enterprise and Education plans have no published prices and are arranged through sales; they cover API integration and, for schools, LMS integrations. The homepage also says free tools for individuals exist, including an AI Detector and a Plagiarism Checker, though the pricing page lists no free plan.

Our take
Copyleaks suits writers, editors, teachers and small teams who want AI and plagiarism checks in a single text report, plus AI image checks, with a browser extension or Google Docs add-on. The Pro plan fits groups, since it includes 25 user seats. It fits less well if you need API access or LMS integration, because those require a custom quote from sales and no price is shown. Credit-based limits mean heavy scanning may call for extra credits or a higher plan. Switching plans overrides remaining credits, and refunds are narrow, so read the details before paying. The pages state no free trial length.
