Description from store
With the award-winning AI Detector, you can quickly and accurately determine what was written by a human and what was AI-generated, even if the AI text was paraphrased or interspersed with human-written content.
Browse with confidence and verify the authenticity of your assignments and writings, social media posts, news articles, and even reviews on your favorite shopping sites. The possibilities are endless.
➤ How it works
Since 2015, our technology has collected, ingested, and analyzed trillions of crawled and user-sourced content pages from thousands of universities and enterprises worldwide to train our models to understand the patterns of human writing. Utilizing AI technology, our AI Detector can accurately recognize the presence of other AI-generated text and the signals it leaves behind, adding an additional layer of accuracy.
We continually test our AI model and retrain it with new data and feedback, helping to improve accuracy. Accordingly, the chance for content written by a human to be falsely labeled as AI-generated content is 0.2%.
➤ AI Detector key features:
• Over 99% accuracy and a 0.2% false positive rate.
• Detect ChatGPT, Gemini, Claude, and more.
• Detect AI content in 30 languages, including English, Spanish, French, German, and Chinese, with additional languages always in the works.
• Detects AI-generated source code.
• Detect AI text even if it was paraphrased or interspersed with human-written content.

- (2025-07-08) Ayan Banerjee: Excellent tool.
- (2025-06-27) Daniel Bell: I tried the tool on some of my own writing to see how it works. It said that the paragraph I submitted was 100% written by AI. I know that’s not true. Does your service guarantee its findings ?

- (2025-05-20) Masadul Mondal: It highlights human written words as AI. i checked with a file which was written before the advent of AI and it still is showing it as written by AI. NOT ACCURATE at all. Very poor.
- (2025-05-15) Deborah Green: Very easy to use. It used to detect all my AI content as AI, which helped me learn how to create prompts that produce undetectable content. Now I use it to make sure it is undetectable, so useful either way.

- (2025-02-14) Mac Samuel: It's only there is no zero star. I just transferred a document from Google Docs to MS Word and 58% AI Appeared tf ???? & when I check the part that it highlighted it gives 0%. Is this thing just a random percent generator ??
- (2025-02-11) Macharia Samuel: It seems that the main difference between my writing and AI-generated work is the use of the phrase "In conclusion." The frustrating part is that my teacher relies on the extension fully not even checking other detectors to evaluate our papers, which forces me to spend hours revising my work—eliminating certain words, replacing others, and sometimes deleting entire paragraphs.
- (2025-02-10) Wendy Evans: Great tool! Love that it's an extension. It makes it very convenient when grading student work.

- (2024-12-12) Life Of Nature: bad
- (2024-12-12) Micheal John: Good for AI content detect I recommend this!
- (2024-12-11) Rajia Qayyum: Not accurate.
- (2024-12-05) Rajjo kakar: Copyleaks has been incredibly disappointing. When I tested it by inputting 3-4 paragraphs together, it incorrectly flagged the content as AI-generated. However, when I submitted the same text one paragraph at a time, it identified it as human-written. This inconsistency cost me a client, which is entirely unacceptable. I expected more reliability from such a platform, and this experience has left me extremely dissatisfied.
- (2024-11-29) gabriel muthama: I am deeply disappointed with copyleaks. For the past like 2 weeks, the platform flags my content as AI-generated. This is not only inaccurate but also damaging, as it undermines the credibility of my work and raises unnecessary concerns about its authenticity. Such errors are unacceptable for a service that claims to provide reliable plagiarism and AI detection. It's infact unrealiable and misleading. Something needs to be done to restore the lost trust
- (2024-11-26) johnstone williams2: Is anyone else experiencing this? I am deeply disappointed with copyleaks. For the past like 2 weeks, the platform flags my content as AI-generated. This is not only inaccurate but also damaging, as it undermines the credibility of my work and raises unnecessary concerns about its authenticity. Such errors are unacceptable for a service that claims to provide reliable plagiarism and AI detection. It's infact unrealiable and misleading. Their AI detection algorithm is flawed and requires immediate improvement. What happens to we subscribers who who rely on accurate assessments in academic and professional contexts? I cannot recommend this service to anyone. Proceed with caution if you value the integrity of your work.
- (2024-11-26) victor odwori: Absolutely useless. Copyleaks constantly mislabels genuine human-written content as AI-generated, completely undermining its purpose. A waste of time and money—do not trust this tool. Its accuracy is nonexistent, making it worse than useless. Complete garbage.
- (2024-11-26) Vic Stopper: Ooh my goodness! This is unethical and unfair business practice for sure. I have raised multple concerns about how Copyleaks AI detector flags my assignments as AI even when I have not used AI. Seems like no one cares. Until when will this continue? Do you even test your products before releasing them to the market? I am so frustrated. You should do better.
