What is Copyleaks AI Detector?
Copyleaks AI Detector checks text for content written by AI models such as ChatGPT and Gemini, and also checks for plagiarism. The same credit-based account also covers AI detection for images.
It runs on credits. One credit covers up to 250 words or one image. New users get a limited number of free credits to try the AI and plagiarism tools. After that, the Personal and Pro plans give a monthly or annual credit allowance. On monthly plans, credits you don't use are cancelled at the end of the month. You can buy extra credits one time if you run out.
The Personal and Pro plans are meant for individuals, such as writers, students and editors. Schools and companies can get custom-priced education and enterprise plans, which include API access and LMS integration.
