Copyleaks AI Content Detector

What it does

The Copyleaks AI Content Detector checks text you find on the web and estimates whether a person or an AI chatbot wrote it. It is built for teachers, editors and everyday readers who want to judge assignments, articles, social posts or product reviews.

Key features

• Flags text that appears to be generated by chatbots such as ChatGPT, Gemini and Claude
• Aims to spot AI writing even when it has been paraphrased or mixed with human text
• Works on content in many languages, including English, Spanish, French and German
• Checks text on any site, from news articles to reviews on shopping pages

Use cases

• A teacher reviewing whether a submitted essay may have been written with AI
• An editor screening a freelance draft before publishing
• A shopper judging whether product reviews look machine-written

Getting started

Select the text you want to check on a page and run the detector from the extension to see its estimate of human versus AI authorship.

Good to know

Results are probability estimates, not proof, and should be weighed alongside other evidence. Text you check is processed by the Copyleaks service.
