Fact-Checking AI Content Is Essential

Fact-checking is time-intensive, yet essential. Misinformation, potential false facts, and AI errors can have huge consequences; just consider the Deloitte scandal and the AI book list scandal.

Originality is a great tool for detecting AI content. The product has been invaluable for our content marketing team. Fernanda and the team are always very responsive and helpful. Highly recommend this product.

Miguel Maloney Thompson

I have the opportunity to make sure that my writing is plagiarism-free, and with a lot of AI-generated content around, I can ensure my writing does not get flagged as just another to the bunch.

I do technical writing where there are only so many ways to describe concepts and ideas. However, Originality.ai gives me the opportunity to personalize my writing even more, which is an advantage. With some time, I can give my content a sense of uniqueness.

John Kohn

John Kohn

Reliable and trustworthy. Originality is always so quick to respond to my questions and lend a helping hand. It’s a very good tool for detecting ChatGPT use on academic papers, especially with the "view writing" feature which shows the text being typed by the student as they were typing it.

Stevie Lambert

Stevie Lambert

AI is accurate compared to free choices and the support staff like Ellie are very helpful. The interface is easy to use and shows a % chance of the work being AI. It’s also, nice that it shows what parts may be AI or not.

There are lots of similar AI detection tools available online but nothing comes even close to what they offer. I can't trust any other tools other than theirs. Have tried maybe 20-30 other websites and settled with them.

I had an excellent experience with the support team at Originality.ai. They were incredibly responsive and provided clear, detailed answers to all my questions. The explanations were thorough, and I now have a much better understanding of how the platform works and how my content is handled. 

The team was patient and professional and went above and beyond to ensure all my concerns were addressed. I truly appreciate their help and the top-notch customer service they provide. Highly recommended!

Originality.ai is the best tool on the market. I have used comparable services and this one is exceptional. It provides an accurate report with a match score which really helps writers/researchers adjust and improve their work. 

There are also advanced features such as paraphrase detection which are not available with any other comparable service. The features provided by Originality.ai are exceptional for users who want to avoid plagiarism and also improve their research process. I hope to continue using Originality.ai for many years to come.

John Willsdon

John Willsdon

This is a really helpful tool. Certainly the best of the AI detectors I tried. What makes it great is that you also get a bunch of other tools that are really helpful. The fact checker is awesome, it gives you feedback on whether or not points in your essay are factual or not by reading the source material in your citations.

I have been using this tool since the start! And it has saved me many times. Many times when checking clients' sites the problem was AI content or plagiarism.

Chris Swanson

When I hire writers, I want 100% human-written content. I depend upon Originality.ai to check this for me.

Dirk Berger

Dirk Berger

Originality.ai saved me from making a big mistake. I have written a book with the help of ChatGPT, 40% of my work is AI; 60% is human. It identified the AI, and now I am writing it all by myself. 88-100% human. Thank you Originality.ai.

Rob McTavish

Rob McTavish

I started to look for an easy tool to confirm my suspicions over some of the material being submitted by my students in first-year Communication courses. I found Originality.ai and tried it out. It worked so well that I actually tested it out with some material I created using AI as an example and sure enough, it perfectly determined which was my work, what was totally AI-written, and what was edited AI material.

Incredible experience. Excellent product. Very easy to use, thorough and informative. Brady was incredibly helpful on the chat. He carefully checked my document to see why it had a high score for AI and then explained it to me. He provided individualized advice on how to move forward. Excellent! Thank you Brady.

Frequently Asked Questions

How accurate is the Fact-checker?

We completed a fact checker accuracy study looking at the accuracy of our Fact Checking aid. The results show an overall 86.69% accuracy. Originality.ai closely tied GPT-5 for accuracy, with a slight lead (Originality = 86.69% accuracy vs. GPT-5 = 86.67%), while decisively beating GPT-4o. However, the accuracy still means that the tool should be used as a fact checking aid and not viewed as the final source of truth.

What kinds of facts or AI hallucinations can I check?

Nearly everything! Check AI-assisted copy for potential AI hallucinations. Then, review AI-assisted or human-written copy for potential inaccuracies. The fact has to be verifiable though, so for example you can’t check “Chocolate ice cream is the best flavour” as this is an opinion. Also, for now we are steering clear of anything political.

Is it multilingual?

In short, no. But watch this space for updates in the coming months!

How does the Fact Checker work?

In short the checker goes through the content per sentence, fetches relevant URLs, and uses their content and your article to verify your fact.

Can I check recent information?

Yes. Our fact-checker is internet-connected, allowing us to deliver results based on the latest information.

What sources does the fact-checker use to verify information?

The Originality.ai Fact Checker has at least 1 source for every identified fact, each with a url, and now a title and date (if relevant). Plus, you can now generate a quick copy-pasteable citation in the style of your choice (APA, MLA, Chicago Notes and Bibliography, IEEE) for each individual search result source used by the Fact Scanner in its evaluation. Additionally, users can now generate a PDF bibliography of citations with all of the sources from the fact checking scan.

Does the fact-checker store or share the information I input?

We value user privacy and ensure data is handled with utmost security. All information concerning our privacy policy can be found here - https://originality.ai/privacy-policy
