The rise of AI content generation tools has made it difficult for businesses and individuals to ensure that they receive top-quality, human-written content.

You may have experienced paying for content that ends up being AI-generated, even though you were promised high-quality, human-crafted work.

That’s where Originality.ai comes in. This powerful tool uses advanced machine learning algorithms to analyze text and distinguish between human-written and AI-generated content. This way, you can be sure that the content you receive is original and of top quality.

But wait! What does search engine giant Google think about AI-written content?

Google’s recent guidelines suggest that AI-generated content is acceptable as long as it’s original, high quality, and people-first content. However, the search engine giant still uses its E.E.A.T. (Experience, Expertise, Authoritativeness, and Trustworthiness) approach to rank blog posts.”

To meet Google’s standards, you need to ensure that your content is not only original but also of high quality, with a primary focus on providing value to the reader, rather than on manipulating search rankings or spamming.

In this Originality.ai review, we will explore how it can help you identify whether your content is written by humans or AI tools, and we’ll also discuss its plagiarism checker feature.

What is Originality.ai?

Originality.ai is a powerful tool built specifically for serious content publishers who want to maintain the originality of their content.

It’s not just a plagiarism checker; it’s an AI detector that can identify whether the content was created by humans or is written by AI tools.

The team behind Originality.ai consists of content marketing and GPT-3 AI experts who deeply understand the needs of web publishers.

The tool includes features like team management, scan history by the user, and most importantly, an AI writing detection tool.

The tool utilizes machine learning algorithms to detect AI-generated text and generate a score based on the text you paste. The result shows the percentage of text written by AI and the percentage written by humans.

It’s an excellent option for web publishers, content agencies, and website buyers who want to ensure that their content is original, plagiarism-free, and not created by AI.

Can Originality.ai Detect GPT-3 and Other AI Models?

Originality.ai has been tested to detect GPT-3 and other AI models, including ChatGPT and GPT 3.5.

In a recent study, the tool was found to have an accuracy rate of 94% in identifying content that was produced by GPT-3.

This level of accuracy provides users with confidence that the content they are receiving is truly original and created by a human, not a machine.

Let’s get started testing out the tool to see how capable it is.

Test Originality.ai’s Ability to Detect AI-Generated Text

To test its capability, I will be providing five human-written samples and five AI-written samples. In addition, we will also test AI-written content with some human touch to verify the tool’s accuracy. We will also test text from some of the most trusted websites to determine whether their content is written by humans or using AI tools.

Human-written Sample #1:

For the first test, I wrote a personal narrative to test the Originality.ai content detection tool.

Result: Here, the results clearly show that 96% of the content is human-written.

AI-written Sample #1:

I rewrote my personal narrative about my trip to test the capabilities of Originality.ai’s detection tool.

Result: The result showed that the tool was able to accurately detect that 98% of the content was generated by AI, demonstrating its effectiveness.

Human-Written Sample #2:

For the second round of the test, I wrote an introductory paragraph on the topic “How to start a blog?”

Result: Again this tool won by scoring 98% original human-written content.

AI-Written Sample #2:

I give a prompt to ChatGPT to write me a blog intro paragraph on how to start a blog that makes passive income?.

Result: Without any doubt, the tool’s capability won by scoring 89% AI-written content.

Human-Written Sample #3:

For the third test, I use a fiction story to check the capability of originality.ai. I use 4 paragraphs from Nancy Christie’s fiction story “12 Days Before Christmas“.

Result: This time it scores 100% original content.

AI-Written Sample #3:

I write a fiction story using AI Tools and check 3 paragraphs of the story.

Result: Again the result is very promising by giving 100% AI content.

Human-Written Sample #4:

For the fourth test, I made the text more complex to see how well Originality.ai can understand it and provide accurate results.

Result: But, this time the tool fails to perform and provides a score of 21% for human-written content.

AI-Written Sample #4:

I was asked the same question from ChatGPT, “How long does it take to travel from Earth to the Moon?”.

Result: Again Originality AI content detection fails to detect and score 66% original content and only 34% AI.

Human-Written Sample #5:

To put originality.ai to its final test, I utilize a frequently used text in an attempt to perplex the tool and observe the results.

Result: It passed and scores 100% original.

AI-Written Sample #5:

Result: Again it fails to AI detect text and gives a score of 87% original and 13% human.

Test the Text from Authority Websites.

Testing the text from authority websites can be a useful way to determine whether the content is written by a human or generated by AI.

By analyzing the language and structure of the content, it is possible to identify patterns and characteristics that are typical of machine-generated text. This can help in assessing the quality and authenticity of AI-generated content, and determine whether it is suitable for use in various contexts.

While automated content creation can be a useful tool, it is important to ensure that the resulting content meets the standards of accuracy, relevance, and value for human readers.

Test of News Website

For my first test, I checked an article from two well-known news websites – CNN and The New York Times – to see if they were written by a human or AI. I chose to test financial articles instead of daily news articles to better assess the capabilities of Originality.ai.

CNN Article: 5 reasons to get the Chase Freedom Unlimited — and 2 reasons not to

CNBC Article: A debt ceiling standoff may trigger ‘serious’ fallout for Americans, warns economist. Here’s what it means for you 

Result: Originality.ai detects that both of these articles are 98% written by AI.

Test of SEO Website

For the second test, I used an SEO news website and a Google article.

Search Engine Journal: LinkedIn: Top 10 In-Demand Skills In 2023

Google Search Central Blog: Don’t use 403s or 404s for rate limiting

The purpose of the test of authority website is to just check whether AI content is work or not and how they use AI content.

Plagiarism Check

Originality.ai is not just an AI content detection tool; it also functions as a plagiarism checker. In this test, we will evaluate the accuracy of its plagiarism checker, which costs one credit per 100 words, making it one of the most affordable options available.

We will use the text from my own article, ‘The 7 Best Autoblogging WordPress Plugins,’ to assess the capabilities of Originality.ai’s plagiarism checker.

The result is amazing as it gives 100% matched content, which is really impressive. Just like its AI detection tool, Originality.ai is also great for plagiarism checking.

I also compared the same text that I pasted on Originality.ai to Copyscape, which costs $0.03 for 150 words. It gave me two pages with the same matched content: one from my website and the other from Instagram.

However, when I clicked on the Instagram link, it showed me “page not found.” This proves that Originality.ai is a reliable plagiarism tool that can compete with Copyscape, one of the oldest plagiarism checkers.

Pros of Originality.ai:

  1. Accurate results: Originality.ai provides highly accurate results, making it an excellent tool for detecting AI-generated text and plagiarism.
  2. Plagiarism checker: In addition to identifying AI-generated content, Originality.ai also serves as a plagiarism checker, allowing users to ensure that their work is entirely original.
  3. API access: With Originality.ai’s API access, users can integrate the tool into their workflow, automating the process of checking for AI-generated text and plagiarism.
  4. Affordable pricing: Originality.ai offers affordable pricing, making it accessible to a wide range of users, including students, educators, and professionals.

Cons of Originality.ai:

  1. Limited language support: Originality.ai currently only supports English language text detection, which may limit its usefulness for those who work with other languages.
  2. False positives: While Originality.ai is accurate in detecting AI-generated text, it may sometimes flag certain human-written content as being AI-generated, leading to false positives.
  3. No free trial: While Originality.ai offers affordable pricing, some users may be hesitant to invest in a tool without trying it first. Not having a free trial can be a drawback for those who want to test the tool’s features and performance before committing to a subscription.

Is there a free alternative to originality AI?

If you’re looking for a free alternative to Originality.ai, there are a few options available to you. While some of these tools may not offer the same level of accuracy or advanced features, they can still help you check your content for AI detection. Here are three free options you can consider:

  • Writer.com: This is a free AI content detection tool that allows you to check up to 1500 characters for free.
  • Copyleaks.com: This free AI content detector allows you to scan your text for similarities with other online sources, as well as to check against offline content. It also has free plagiarism checker.
  • Corrector.app: This AI detection tool allows you to check up to 300 words for free.


Originality.ai is a valuable tool for businesses and individuals who want to ensure that the content they receive is of top quality and human-written.

Its ability to detect AI-generated text with 94% accuracy provides users with confidence that the content is original and created by a human, not a machine.

However, the tool is not 100% accurate as it failed to perform in some cases. The team behind Originality.ai consists of content marketing and GPT-3 AI experts who deeply understand the needs of web publishers.

The tool is suitable for web publishers, content agencies, and website buyers who want to ensure that their content is original, plagiarism-free, and not created by AI.

In summary, AI-generated content is not bad until it gives you the correct information and is checked by humans, and Originality.ai is an effective tool that helps to solve the problem of publishing less AI-written articles.


Can AI-generated essays/poem be detected?

The answer is not so clear-cut. While Originality.ai is effective at detecting plagiarism in text-based content, it is not yet advanced enough to detect AI-generated poetry or essays.

AI-generated content often uses complex algorithms and techniques to create unique pieces that can be challenging to differentiate from human-generated content.

However, as technology continues to evolve, it’s possible that AI detection tools may be able to detect such content in the future.

Is AI written content good for SEO?

In today’s digital era, AI-generated content is becoming more prevalent. One question that often arises is whether AI-written content is good for SEO.

As I mentioned above in the introduction, according to Google’s new guidelines, automated or human-generated content is accepted as long as it is not spamming the search engine and is written for people first.

AI content can provide significant benefits to website owners by providing fresh and unique content that is tailored to specific audiences.

But, it is important to remember that content generated by AI may lack the nuance and creativity of human-written content. Therefore, it’s essential to balance the benefits of AI-generated content with the need for high-quality content that resonates with readers.
