Originality.AI is an AI and plagiarism-detecting tool created for web publishers. It’s a tool trusted by the likes of Neil Patel, a top marketer, and other top brands.

What Is Copyleaks?


Just like Originality.AI, Copyleaks serves both as an AI detection and plagiarism-checking platform. Founded in 2015, it now has millions of users globally, something attributed to its focus on empowering originality and authenticity.

One of its founders, Yehonatan Bitton, discovered that competitors plagiarized his family’s business website content. This led to a decline in online visibility and sales. As a result, he and his workmate, Alon Yamin, created Copyleaks to prevent such from happening to others.

Originality.AI vs Copyleaks: Features

Originality AI Features

1. AI Content Detection

Originality.AI is known for its AI content detection abilities more than anything else. If you need to know if something was written by AI, this tool can simplify the process for you.

I tested Originality.AI and found out that it was much better at detecting AI content from ChatGPT (a free text generation platform) than other higher-quality AI writers like Jasper.

2. Plagiarism Checker

If you just want to know whether any text was copied from somewhere else, Originality.AI can also assist with that. It utilizes sophisticated AI algorithms to analyze submitted text and compare it against its extensive database.

The tool’s algorithms consider not only exact word-for-word matches but also more nuanced similarities, such as paraphrasing, rewording, and structural similarities. This ensures a thorough examination of the text and provides you with comprehensive plagiarism detection.

I even took one of my previously published texts and pasted it into Originality.AI’s detector. It showed 100 percent plagiarism and the source of the copied text (my site in this case).


I’m confident that this tool can locate any duplicate content on the Web as long as it’s discoverable and accessible to the public.

3. Site Scans

It can be that you just want Originality.AI to find out any occurrences of AI on your web pages or the entire site. Well, the tool is also built for that purpose!

Copyleaks was initially created as a plagiarism-checking tool. So, this is one of its best features. The tool can identify any cases of plagiarism using its advanced AI capabilities.

Copyleaks plagiarism detector is powerful because it can find:

  • Text variations: Even if the copied content has some variations, Copyleaks can still sniff that out. In other words, you’ll be able to see any rephrased text that was originally yours.
  • Image-based text plagiarism: This refers to the copied content that is placed on images. It’s possible through the power of optical character recognition (OCR), whereby text on images can be read.
  • Plagiarism in source code: Plagiarism isn’t just about text and can also involve code. Copyleaks can detect any acts of copying or closely imitating someone else’s code without proper attribution or authorization, whether done directly or with modifications. It can check for originality in multiple programming languages, including JAVA, Python, and C++.

2. AI Text Detector

Copyleaks also offers AI detection as one of its features. The tool can identify any text straight out of ChatGPT, among other AI writing tools.

I also tried out Copyleaks to determine the power of its AI detection function. One thing I noticed is that Copyleaks misses some AI-generated text that Originality.AI figured out.

Also, the tool sometimes mislabelled my authored text as being AI-written.

3. Multiple Languages

Copyleaks not only detect unoriginal or AI-generated English content but also other popular languages. The other languages include French, Spanish, German, Italian, and Russian. So, if you aren’t a native English speaker or are publishing content for a global audience, you’ll find Copyleaks useful.
