Faisal Saimeh 2026-03-16: Very helpful in detecting Ai content and great customer service
Jason Cormier 2026-03-12: Fantastic Chrome extension to detect if the content was written by AI.
Katherine 2026-03-12: The originality.ai tool is a great tool for teachers and others alike who want to quickly and easily check students’ work. It’s such a comprehensive tool in that it lets you check for plagiarism, AI-generation, and facts, but also for grammar, spelling, student achievement levels in reading and writing measurements, and readability. It’s super helpful in giving suggestions to the teacher on how to optimize the student content and improve writing. It gives easy to read suggestions on all the text that you upload and scan in the tool. I like how it gives a percentage and likelihood of how much of the student text was most likely AI-generated, thus allowing me to check in with my students and encourage them to produce original work! And you can download reports of what you find in a student text, which can be helpful when you meet with a student and you can go over a summary of the results with them. It could be a little better as a tool, such as fixing up the main screen and making it look a little easier and more user-friendly to navigate. There’s also not a lot of ways to know how to use it and what are all the tools in it, you have to figure it out on your own. And you have to buy credits to use it, but it’s not clear how many credits it takes to do what. Otherwise, it’s a really helpful tool to assess students’ work and whether they are understanding, producing, and creating on their own and keeping true to their honor and integrity as learners!
sanjay 97 2026-03-12: Very helpful in detecting Ai content. I'm using it since it's launched and it helped me a lot with my website content.
Mohd Yaseen 2026-03-12: I have tested this extension on many of my documents, and my overall experience has been positive. Both the extension and the web application run smoothly, and the interface is well designed and easy to navigate. The extension integrates well with webpages, and features such as document scanning, suggestions, fact-checking, and Google Docs writing capture provide meaningful value—especially for educators concerned with academic integrity. One feature I particularly admire is the video frame used with Google Docs, which monitors the writing process and can help track a student’s writing flow. Although there are areas where detection accuracy and usability can be further improved, the platform shows strong potential.
Irshad Hussain 2026-03-10: This extention is one of the best AI-detection and plagiarism check tool. - It doesn't disturb the normal usage of the browser as it sits on the screen anywhere you want. Drag and position. - The small window that popsup when you click the icon offers a very beautiful and descent look with minimum but full conrol button there. - The super refreshing thing about this extension is when you work on a google document, you can replay the screenrecorded video captured by the tool. It's really AWESOME. - For accuracy, it stand tall, both in AI content dectection and Plagiarism check. I highly recommend this tool to my students, teachers, and colleagues alike.
Kent Jaspher 2026-03-09: Originality.ai gives a straightforward and professional AI detection experience by its well-ordered interface and well-designed Chrome extension. The setup process is very intuitive and the integration of the tool is very seamless and it does not noticeably affect browser performance in day-to-day browsing and even when scanning longer document. The platform's minimalistic design makes it easy to navigate and its features which includes the built-in accessible API tools make it convenient for both casual users and more technically inclined users. While using it, the tool accurately detected clearly AI-generated content and quickly delivered results, with an intuitive probability scoring system that is easy to understand. The credit system is clear and fair, with word-count indicators that allow users to estimate credit usage before running a scan. While the tool works well overall, there are minor areas of which improvements can be done and further enhance the experience. Polished writing may occasionally be detected as AI-generated which suggests that further calibration for structured human writing could improve the accuracy of the tool. In addition, clearer explanation for the flagged phrases and slightly more intuitive scan-type icons would help the users understand the results and make the user interface more intuitive. All in all, Originality.ai is a reliable and efficient AI detection solution for students and professionals that are concerned with content authenticity. By giving continued updates and refinement to the tool in terms of transparency and detection sensitivity, the platform itself has a strong potential to become an industry-standard tool for maintaining academic and professional integrity.

Paul Bryant 2026-02-23: Really nice extension, it's pretty impressive how well it can detect AI content. Really easy to use straight away. The free scan is great but the real power comes once you pay for credits to use on the more advanced features. Fully recommend.

Sherice Jacob 2026-02-18: I work with a lot of writers, and although I'd consider myself above average at spotting AI, this tool builds on what I know and takes it to the next level. I don't have to stop what I'm doing in order to check a text for plagiarism or AI, the Chrome extension handles it, and being able to "Watch a Writer Write" is fascinating, as I can see their process as they go through it, without having to install intrusive apps on their screen.
Jess Sawyer 2026-02-18: An excellent tool for detecting both actual AI-generated text and text that just *sounds* AI. As a writer who wants to make sure my original work actually sounds original, Originality.ai scans have become an essential part of my workflow.
James 2026-02-16: Works so well. There is also the option for a Deep Scan, which does require more credits but is extremely helpful.

Joshua Moshood 2026-02-13: This is a very handy and reliable extension, definitely worth every penny. I was honestly shocked by the amount of AI-generated “slop” I’ve been seeing in my emails, financial news articles, and even some LinkedIn posts lol. Having a tool like this makes it way easier to separate authentic content from low-quality AI content and BS.
Alisa Taylor 2026-02-13: Super helpful and really intuitive to use! The AI detection and plagiarism feature is very reliable, and I especially like the Google Docs Replay feature. This is a great tool for teachers and colleges who want to maintain academic integrity. I also liked that I could test it out before subscribing.
kris creative 2026-02-12: if you ain't using this in 2026, wyd??? genuinely could not live without this tool, if i had a dollar for every completely ai generated email ive received i probably wouldn't need to even have an inbox. its so easy to use, literally highlight and right click on anything and it'll tell you if it was ai generated such a lifesaver for my business when sending brand pitches, writing captions, and working on internal copy, i want to make sure my writing sounds like me and not generic AI bs, so i run literally everything through originality. if i could give 6 stars i would.
Ahmed Ali 2026-02-12: This extension is essential for ensuring your content remains authentic, accurate and human. The real time detection and revision history tracking provide a level of transparency that no other tool matches. It's fast, reliable, and worth every penny for anyone who values original, high quality writing.
Narcis Bejtic 2026-02-12: The most accurate AI checker I've ever used and so easy to scan any content on the web or in google docs. I use it every day in emails and writing content. This tool is a must-have!
Sri Krishna Mannem 2025-12-28: I am giving this is a 1 star because it broke several MBA admissions websites on my chrome browser and I had to write to admissions offices technical teams to address this. For instance, this extension broke the websites at https://apply.chicagobooth.edu/ and https://grad-admissions.wharton.upenn.edu/. So, great on originality, but very poor on execution. I have no idea if you injecting some stuff into these critical websites and why-which raises further ethical concerns for this extension as well. For developers, by break I mean I am not able to fill in anything on the sites I mentioned. It means the sites were completely useless. As long as I have extension installed, I only get this error: "One or more fields contains incorrectly-formatted data: Value cannot be null. Parameter name: g".
Juli R 2025-12-17: Not sure if it works since it keeps asking me to log in after trying 5 times...
yaru _umi 2025-11-21: It helped me during school when I need to improve on my classwork. Giving me amazing and reliable feedback on my skills.
