Verify what content was written by a human or an AI chatbot with the AI Content Detector browser extension from Copyleaks.
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.

Latest reviews
- (2023-11-15) Kartik Bisht: It is best in the market just go for it.
- (2023-11-14) Yuukasta: I have a teacher who swears by this program. I have tried inputting my own written text which come out 100% AI. I have typed my own essay just using CopyLeaks and still, 100% AI. However, I had ChatCPT write a paragraph and then I retyped it word by word into the program and low and behold, it is detected at 100% human. This is highly unreliable for teachers to use.
- (2023-11-05) Cenny Wenner: 100 % unreliable. You can literally type something new into their box akin to literary text, and have it come out as AI. Do not trust any claim of this site or extension. It is literally worthless and in fact, the LEAST reliable of all the AI detectors. It has made false positives so many times on various texts and I have spent HOURS rewritting texts from scratch and still have them incorrectly flagged and only by this site. I have and I recommend others to report it to Google for its fraudulent claims.
- (2023-10-29) Leo: I was just curious to see if this worked so I copy pasted something directly from an AI content generator and it did say that was AI generated. I tired mixing in AI and Human writing but the extension said 100% AI generated. So I was like uh that's not correct so I wrote something completely myself and this said it was all AI written? I'm not sure if it is my writing style or not but this seems to just call almost everything AI. Would be great if this actually worked though. I hope no teachers are using this to check students.
- (2023-10-27) Tú Trần: Ok good
- (2023-10-25) Mahad: is good and accuratly But remove the log in option
- (2023-10-18) JCDenton Alex Melyon: Kinda OK, But I must log in and have to copypaste or select text manually. I thought it will be automatically.
- (2023-10-11) Paul Udor: It prompted me that some of my researched and written texts are AI-generated. Then, after re-writing and re-editing, some were passed as human-written text, while some are still showing that it is AI-generated. I even typed a different paragraph in the extention textarea and I still got an AI-detected prompt. Worst part is that it doesn't even show the percentage probability of AI. Copyleaks AI detector tool has been making content writing more exhausting recently. I don't think it's accurate in detecting AI-written text, and it is making lose client as a content writer.
- (2023-10-07) James Walsh Dick: Soy instructor universitario y probé este producto para verificar los trabajos de mis estudiantes después de algunos incidentes comprobados del uso de ChatGPT y otros tipos de inteligencia artificial en ciertas secciones de mi curso. La calidad de este programa es pésima, a veces da dos resultados diferentes para el mismo texto si se introduce en dos días distintos, y es muy fácil confundir el programa por cortar pedazos de un texto, por ejemplo un ensayo de seis páginas en sí puede dar un resultado de 100% limpio, para un párrafo extraído del mismo ensayo puede dar un resultado de 100% AI, que racionalmente no es posible. Además he comprobado con artículos que yo mismo he escrito y con párrafos que he visto a mis estudiantes escribir con mis propios ojos que Copyleaks frecuentemente da falsos positivos, haciendo el programa enteramente inútil y no una herramienta confiable para comprobar la presencia de AI en un texto. Es posible que funcione mejor en el inglés, pero para textos en español es inútil hasta el punto de ser peligroso su uso en un contexto institucional.
- (2023-10-06) Svetlana Pantelejeva: 7 palabras iguales copiados es texto Humano. Mi solicitud con 20 palabras es AI 100%
- (2023-10-05) M ANWAR: 3weeee
- (2023-09-23) Eva Fernández Dirienso (Eva.F.D): Hasta ahora me funciona
- (2023-09-10) Imaginer 1234: I've played around with quite a few ai content checkers to see how accurate they were, and this one that I came across recently seems really efficient at it's job. Highly recommend!
- (2023-09-06) Malay Sherasia: Great App to detect AI created content, especially for SEO industry.
- (2023-09-04) Federico: Ho provato con un testo che ho scritto io e mi da 84% scritto da ai
- (2023-08-31) Delnick Talleres: Falta mejorar el algoritmo. Marca todo como IA y el cupo diario es muy limitado (versión gratuita)
- (2023-08-31) Potato King: Very good AI detector! Works 100%
- (2023-08-29) play chris fer: Todo lo marca como generado por AI, esto no sirve
- (2023-08-27) Sanchit Kumar: Perfect results
- (2023-08-23) Fernanda Lee Martínez Cairo: I've just copied a text writted by me and it said that it was 98% AI Content
- (2023-08-23) Mohammad Azzam: Literally opened ChatGPT and selected the below text and the extension showed me "Human Text" As of my last knowledge update in September 2021, there wasn't a foolproof or widely established tool specifically designed to definitively identify whether a given text was generated by AI (like GPT-3) or written by a human. However, I can provide you with some general strategies and considerations that might help you distinguish between AI-generated text and human-written text:
- (2023-08-21) Jonathan Rodrigues: Funciona excepcionalmente bem, raramente apresentando resultados inconsistentes. Incrível!
- (2023-08-14) Everton Luis (Ever): Funciona muito bem na maioria abosulta dos casos
- (2023-08-12) marwa numan: big good
- (2023-07-31) TheBlackwave: Incredible extension, to be honest, this was great and removed my doubts of "This really look like a Chat-GPT generated message".
- (2023-07-12) Alok Kumar: This tool clears my doubts
- (2023-07-02) Igor Z.: A very good app!
- (2023-06-29) Jasper Fox: This tool obviously has no idea what it's looking at. I presented it with both AI content and content I typed in the response box multiple times and it just assumes everything is written by AI, i'd assume mostly based off of spelling/grammer checking as well as what websites you have open, because one piece of text i checked while i was on chatGPT and it immediately said it was AI generated. I then opened a new browser went to a blog website and copied the exact same text into the check box and it said it probably wasn't AI. ...This is really disappointing. now everyone that trusts this tool is goin to think literally almost anything is written by AI.
- (2023-06-27) Jessica Johnson: Claimed some of the text I wrote was AI even after rewriting it different ways a couple times.
- (2023-06-26) Gel: It rated a 2,000-word article that I've written as 100% AI-generated. Really, 100%?
- (2023-06-03) Anonymous A.: 1. This app only detects AI text. There is no good reason a personal account needs to be made to use such an impersonal service. 2. Failed to detect a basic "Write a poem" response from ChatGPT 3.5. 3. Does not highlight text automatically, requires you to paste it in, which no reasonable person would do on every site and every piece of information they read. 2/5
- (2023-05-25) Junaid Imran: v slow
- (2023-05-20) Petia Nikolova: Of course we can't know how helpful or useful this plugin really is, as stated below, it's an AI judging another AI. Better to be safe than sorry, when the extension tells me it's sensing some AI content, I run it through QuillBot or manually change a couple of sentences. It's a really useful app and I'm happy you guys made it into an ext. Thanks.
- (2023-05-14) Mohsen Fouladi: I tested it for several times and found no lapses of judgment
- (2023-05-11) Toku Shimoyama: Amazing extension - Great at detecting AI generated content!
- (2023-05-11) Aaron Hulbert: Incredibly useful!
- (2023-05-08) Chocolate Candles: great, use it to check texts
- (2023-05-07) Jean-Yves BERNARD: This looks to work fine until ... I test it on one of my own article that I have written 15 years ago. It detected it as AI generated with 98% of confidense ... When a text is very neutral, very classical, it put it as AI generated !
- (2023-05-07) Dina Bavli: Works great! super fast and accurate
- (2023-04-18) Irakly Partsvania: Super!
- (2023-04-04) M R: Most of all website texts are just marked as 99,9 ai content - although they were written by humans and most of them have been online long time before AI was on the market!!!
- (2023-03-21) Shalev Roimi: Works great, a reliable and user-friendly tool.
- (2023-03-19) Burger Zay: it's alright. i use it to check over my essays before turning them in. But when my work is 100% human, it says it's 99.9% AI. Other than that it's pretty reliable.
- (2023-03-14) Matin Khan: Very Beneficial.
- (2023-02-08) Shouvik Paul: Love it! Easy to use and I've been scanning a lot of the news articles that I read to see if they're being AI generated.
- (2023-02-08) Gabriel Siegel: Completely delivers on the extension's promises

- (2023-02-07) Willo Darling: I have tried this Extenstion across multiple forms of content, even including articles from major publications and it's been an eye-opener to say the least. It's fast, it's been extremely accurate every time, and I've already noticed they've done some updates so it's constantly getting even better. Awesome Extenstion for AI content detection.
- (2023-02-07) Chad Horner: If it's important for you to know if something was written by a human or by AI, then this is the tool I would recommend. It's fast, easy to use, accurate & FREE!
- (2023-02-07) Aimee Hedges: Works very well, I have tested it against several AI bots!
