So what can we learn from this? In many cases, the tool tells the right story, even when it's nuanced, like in the case of AI content edited by humans.

Gael Breton

At Clicking Publish, producing original, high-quality content is essential to our success. To maintain these standards, it's important that we verify the work from freelancers and outsourced writers. Originality.ai makes this process easy for us by providing a simple and efficient tool that ensures the content we receive meets our expectations.

Kityo Martin

After testing a number of AI content detection tools, I have found Originality.ai to be one of the best on the market. And now with the ability to detect paraphrased AI content, Orignality.ai is even more powerful. It’s basically my go-to detection tool at this point.

Glenn Gabe

I realize that AI content isn't going away and with human editing, it can save time/make blog content better. That said, I've also had writers submit content that was 100% AI and never told me. A BIG no-no. This tool (Originality.ai) is what I'm using to stop that.

Ron Stefanski

Have you played with originality.ai yet? So far batting 1000 on everything I've tested. Very cool tool. Not knocking the makers when I say this... if they have it, Google definitely has the same ability 10x.


Great test and analysis. I tested a few that used Jasper (no edits) and saw 99% Al for most. Were you testing ~100 characters or the whole posts?


For all writers and article buyers: Fantastic tool to detect if written content was created by Al or not: app.originality.ai

Michel Rossier

As expected, the human-written content received a 100% originality score and 0% AI. Conversely, the Jasper-written content was detected to be 95%Al and only 5%, human.

Saeed Ahmed

The new Originality Al tool by @nichepursuits does a good job at identifying long-form content created by Jasper's Blog Post Workflow


Love seeing people try out the Originality.ai tool! "Does a good job identifying content created by Jasper.

Spencer Haws

Yes, tried writer.com and didn't find anything, but with originality.ai found 100% match for GPT and 0% match for plagiarism.

Genc Arifi

I checked through writer.com and Content at Scale. Both gave massively high human content probability.

Soumitra Sengupta

Nicely done, I've been wanting a tool like this for a little while now. We'll definitely be checking this out!

Jonah Matthe

Congratulations! You have done something which the behemoth Google has not figured out how to do yet!

Sourav Das

Use this for trends amongst writers to find the ones getting really bad scores consistently. I would not use it as a one and done tool, more for trends because of false positives. Ex. I confronted this writer, they initially denied it, then admitted to using ai, had the highest scores when averaged over all other writers.

Andy Belov

I love the tool. Not only does it detect ACTUAL Al written content, but also writers who write just like Al. Great way to weed out Al and poor writing. Just because content was written by a human doesn't mean they did any better than an Al tool. We had a lot of our writers test positive for Al and they didn't use Al. What was common in all their writing was the lack of original thoughts. It was all regurgitation.

Ryan Cunningham

After doing some serious testing with Originality (which caters for the newerAl tech), I can't fool it (yet).

Joe Davies

Detecting Ai content has become the most significant pain in the ass, I just signed up on Originality.a, and I am just fascinated.


That's a great read Jon, thanks for sharing! I've only tested the one ChatGPT-assisted article through Originality.ai so far, but am keen to do more. It's a brilliant tool you've created and is going to help so many website owners make sure their writers are on-point.


Originality.Al Launches the First Al Tool Available to Detect AI Content. With the proliferation of artificial intelligence (AI) writing tools publishers are concerned that the content being created by their write.

MarTech Series

I tried your prompts (and other ideas) and I think the issue here is that you're using a GPT-2 detector on output generated by GPT-3.5. Chat GPT is too smart for it! I used Originality to check the results and it can't be fooled.

ChatGPT lacks empathy and originality. It’s also recognized as AI-generated content most of the time by plagiarism and AI detectors like Originality.AI

Ashley Stahl


Jon Gillham, Founder of Originality.ai came up with a tool to detect whether the content is written by humans or AI tools. It’s built on such technology that can specifically detect content by ChatGPT-3 — by giving you a spam score of 0-100, with an accuracy of 94%.

Felix Rose-Collins


After extensive research and testing, we determined Originality.AI to be the most accurate technology.

Originality.AI is a plagiarism checker and AI detector that is specifically designed for serious content publishers. It allows users to check the originality of their content by identifying any plagiarism and detecting if AI tools like ChatGPT were used to create the content.

Mohammed Wasim Akram


Whilst the Originality.ai browser extension for simple AI checks is free of charge, the pricing for larger-scale usage is $0.01 per credit (1 credit scanning 100 words). In short, for an 800-word feature, the cost of checking for AI-generated content is 8 cents.



If you're looking for an industry-leading content checker that will determine if writing is both plagiarized or written with AI, check out Originality. This tool uses a combination of GPT-4 and other natural language models (all trained on a massive amount of data) to determine if content seems predictable. Originality seems to be the only non-official AI content detection tool accurate for both ChatGPT & GPT 4 (the most advanced generative language tools).

Justin Gluska


Based on my testing, I’m impressed by Originality AI. I like it enough that I spoke with its creators, and they kindly extended a discount for my readers.

“We wanted to be able to provide publishers data showing that the content they were going to publish is truly original,” said Gillham. “For us “original” simply means both free from plagiarism and created by a human, not a bot.”

AIT News Desk


A recent study showed that Originality.AI was successfully able to detect AI-generated content by several of the most popular tools including Jasper.AI, Rytr.me and WriteSonic.com.



The team at Originality.AI is excited to announce the creation and launch of the world's first AI that is built and trained to predict when a block of text has been created by any of the popular AI tools (covering the natural language processing (NLP) models GPT-2, GPT-NEO, GPT-J and OpenAI's latest GPT-3).



Google has said that Al-generated material is not allowed if no more value is added. Uniqueness is intriguing. Originality Al detection provides a powerful plagiarism detection module with capabilities that are presently unavailable but are essential for publishers that manage a team.

Gilham and co-founder Conor Watt farmed the project out to developers who created a machine learning algorithm trained on the most popular natural language processing models. Unlike Hugging Face Inc.’s AI detector, which uses probabilistic techniques to guess the words an AI content generator is most likely to use, Gilham said, “our AI is much heavier on the compute side and looks at the article holistically, not using a linear function.” He noted that a recent test on a small corpus of articles generated by ChatGPT yielded accuracy rates of over 98%.

Paul Gillin

Can Originality.AI Detect Chat GPT Content?

Yes, Originality.AI can detect ChatGPT content. 

Can Google Detect and Penalize AI Generated Content?

We completed a correlation study of 20,000 web pages and identified a small correlation between Originality score and Google search result ranking. Potentially indicating that AI content performs worse in Google than Original content. 

Google has said that the appropriate use of AI to make content more useful is not against their guidelines. 

However, they have cotninued to be clear that the use of AI in an effort to game search results is against their guidelines. “Using automation—including AI—to generate content with the primary purpose of manipulating ranking in search results is a violation of our spam policies.” https://developers.google.com/search/blog/2023/02/google-search-and-ai-content

Or worded another way from John Mueller…


At Originality.AI we are not against AI content but believe that the decision to accept the Google risk of publishing AI generated content should be the decision of the website owner and not the writer. 

Do Credits Expire?

Yes, per our Terms and Conditions credits expire in 2 years from the date of purchase.

Do you Have a Plagiarism Checking and AI Detection API?

Yes, we have a robust API and have integrated it into the content operations platforms for some of the largest publishers / writing agencies and marketplaces in the world. 

Full documentation is in the backend. If you have a unique use case or are wondering about capabilities to handle your volume please reach out and we will be happy to discuss your needs.

How Does AI Detection Work?

Our internally built artificial intelligence uses supervised learning with multiple models including a modified BERT model to predict if content is AI or Original. Our AI has been provided with millions of records both AI and Original content then trained to tell the difference between the two. After each training session a large test data set is used to evaluate if the new model is an improvement or not. 

What Do AI Detection Scores Mean?

AI detection scores are a prediction on the chance that the text submitted was AI generated or Original. They are not a measure on the amount of AI vs amount of Original content in a given text. 

We recommend not applying a similar “hard” rule when it comes to working with AI scores and writers. If a writer consistently has high Originality scores but then on one article has a higher AI score, this could very likely be a false positive and further investigation should occur. 

Here is our guidance on how to interpret the AI scores for writers.

Does Originality.AI Provide Paraphrase Detection?

Yes, Originality.AI’s AI is the only available AI that has been trained to detect if content has been paraphrased with a tool like Quillbot. If a piece of text, regardless of whether it started as AI or Human, is run through a paraphrasing tool like Quillbot Originality.AI will identify the content as AI generated 95% of the time.

What Can Cause False Positives?

False positives in AI detection do occur and we are sorry if Originality.AI identified your content as AI. It is different for every tool and a specific reason on what the AI identified as causing it to predict the con

Here are 7 tips for minimizing false positives…

  1. A detection score of 60% Original and 40% AI is not a false positive. It correctly predicted with 60% confidence that your content was Original. The meaning of the score is not that 60% was Original and 40% was AI it means it is 60% confident the content is Original.
  2. Editing AI-written content is not a false positive - it is a true positive
  3. Having AI edit your work is not a false positive - it is a true positive
  4. When any amount of AI touches the content it can cause the entire article to be flagged as AI
  5. “Cyborg” writing where a lot of AI tools are used to create an outline, suggest edits, optimize the content can increase the chance of a higher AI score. (For this reason we created a free content optimizer tool similar to SurferSEO or MarketMuse but 100% free that does not use AI to reduce the chance of a false positive occurring.)
  6. Strange formatting can reduce the accuracy of the detector tools causing an increase in false positives or false negatives. 
  7. The shorter the text the less accurate the detection score. We recommend at least 100 words being checked. 

We apologize if our tool has incorrectly identified your writing as AI!

What do you do if you have been falsely accused of using AI?
  • See our in depth guide on avoiding and managing AI detector false positives 
  • Students - Make sure your teacher is educated on the current AI detection accuracy. Provide any details you have on the creation process. Using a Google Document and providing a screen recording. An AI detection score alone should not be used for academic integrity discipline. 
  • Writers - Create your content in a Google Document and share the free Originality.AI chrome extension with your clients so that if there is any False Positive you can prove you created the document. Share how we recommend people use the AI detection score. AI detection is not the same as plagiarism checking and should have a more nuanced approach to what is and is not acceptable.    
  • Agencies - The first thing any content agency needs to be doing is to define if it is acceptable for writers to use AI and if it is not then develop a process for checking. If you are choosing to use AI in producing content then make sure to communicate that transparently with clients. If you have clients that have accused your agency of having content produced by AI rather than human than refer to your company's policy/procedure for checking work and show the scan history of the writers work. 
False Positives - What Do I Do If I Have Been Falsely Accused of Using AI?

A false positive is when human-written content is identified as AI-written text by an AI detector. False positives do occur and can cause a lot of pain. Across hundreds of thousands of tests we currently see false positives occurring about 2% of the time that human work is submitted. 

2% false positives, despite being the lowest in the industry based on our accuracy test, is too high.  

The AI researchers and machine learning engineers at Originality are working constantly to both improve detection accuracy and reduce false positives. 

We are heavily focused on equipping writers with tools to help them prove their contents Originality.

It was for the purpose of helping writers prove that their work was original that we developed a free Chrome Extension that allows anyone to visualise the creation process of a Google Document

How Does Originality.AI Compare to Other AI Content Detectors?

Originality.AI is the most accurate AI content detector producing the fewest false positives while also the only tool that accurately identifies a piece of content (human or AI) that has been paraphrased. 

See the complete study analyzing how Originality.AI matches up in detection capabilities to other AI detectors here - See Case Study.

The image below shows the results of a test of 1200 text samples, 600 AI generated and 600 human generated tested across multiple AI detectors:

The table below shows the features Originality.AI has including…

  • AI Detection
  • Plagiarism Checking
  • Paraphrase Detection (only tool to offer this)

Originality.AI is more than an AI detector. We are an innovative organization building out a comprehensive suite of content QA tools that will help you gain control over the quality of your content. Readability scores will be added in the near future. 

How Accurate is Originality.AI AI Content Detection Tool?

On the last OpenAI GPT-4 model we tested Originality.AI and the results were it was 99.37% accurate with 1.56% false positives on the known human text. AI detection is different for every model. Below are the detection rates when testing Originality.AI:

  • GPT-3.5 Detection Accuracy: 99.9% accurate
  • ChatGPT GPT4 Detection Accuracy: 83.29% accurate
  • GPT-4 Detection Accuracy: 99.5% accurate
  • Paraphrased (quillbot) Detection Accruacy: 94.7% accurate

See our complete AI Detection Accuracy study to see how Originality.AI compares to other AI detectors. 

For all tests we include various human datasets to know what our false positive rate is. It can range from 1.56% to 2.7% in our tests.

The image below is what is called a “confusion matrix” that is used to assess the accuracy of a AI prediction machine. Each prediction our AI makes on a test data set is grouped into one of four buckets…

  • True Positive - AI detector correctly identified AI content as AI
  • False Negative - AI detector incorrectly identified AI content as Human
  • False Positive - AI detector incorrectly identified Human content as AI
  • True Negative - AI detector correctly identified Human content as Human

The image below shows the confusion matrix for Originality tested on GPT-4 generated content. 

What is AI Generated Text?

AI-generated text is words that have been written by Artificial Intelligence (AI) specifically using Large Language Models (LLMs). The most common example is OpenAI’s ChatGPT which is an AI using OpenAI’s NLP Models (GPT-3, GPT-3.5 and GPT-4) to understand a users prompt and provide a written response.

For the purposes of AI text detection we aim to flag any content that has been meaningfully changed by AI. We try and take an approach consistent when defining what is Plagiarism “Presenting work or ideas from another source as your own.” when training our AI detection model. 

Slight editing with Grammarly or similar is NOT considered AI generated. 

For reference here is what we aim to identify as AI or Original…

  • AI Generated and Not Edited =  AI Generated Text
  • AI Generated and Human Edited = AI Generated Text
  • AI Outline, Human Written and heavily AI Edited = AI Generated Text 
  • AI Research and Human Written = Original Human-Generated
  • Human Written and Edited with Grammarly = Original Human-Generated
  • Human Written and Edited = Original Human-Generated
