The progress we’ve seen in the last six months in AI writing is remarkable, especially with the recent launch of ChatGPT. Not only can ChatGPT generate text that reads like a human, it even sounds like it was authored by an industry expert.

AI-content writers can write a wide variety of content, including emails, blog posts, essays, code, and more.

However, AI content is not always accurate. There are several limitations, which we have covered extensively on our website.

For this reason, it is essential that AI content be proofread and edited by humans before it is published for all eyes to see.

Well, how can we determine whether a piece of writing is AI-written or human-written?

The use of AI content detector tools is one way to detect whether the text is AI-created. If you’re looking for a content detector that uses artificial intelligence, look no further. In this Crossplag review, we take an in-depth look at the Crossplag AI content detector and explain if it is one of the best tools for detecting content.

What is Crossplag?

As previously mentioned, Crossplag is an AI content detector. It’s very simple, so we won’t spend too much time describing how it works; rather, we will focus on demonstrating what it does and how it practically works.

Crossplag uses a combination of machine learning algorithms and natural language processing (NLP) techniques. Using these techniques, it is trained to learn patterns and characteristics so that it can accurately guess the source of the text: Human or AI.

Easy, right?

Although it seems simple, there is a lot of work done in the background using advanced machine learning and natural language processing techniques.

Key Features of Crossplag

Right now, the feature list of Crossplag is short and sweet. It offers AI content detection in addition to a plagiarism checker geared toward educational institutions.

The plagiarism checker is actually nifty, in that it offers both single-language and translation plagiarism checking.

Crossplag also takes IP rights and data privacy seriously, and institutions can take full control of the data that is shared on the platform.

Crossplag’s AI-detecting functionality is in its infancy as it was recently launched. As AI becomes more sophisticated and new features are launched, we will keep expanding this post.

Signing up for Crossplag

Signing up for Crossplag is easy.

  1. Create an account.
  2. Paste your text.

It’s a plug-and-play solution. You can get a free trial to test out the functionality for a limited number of words. Pricing is further discussed below.

How accurate is Crossplag’s AI detection?

We tested Crossplag’s AI detection features by putting it through six tests.

  • We generated 3 different types of AI-written content using ChatGPT.
  • We used 3 human-written pieces of content, two from our website (that were written by us!) and one from a Forbes article (which is presumably written by a human!).

In an ideal world, the ChatGPT content will be flagged as 100% AI, and our pieces will be 100% human.

Let’s see what the results say.

AI-Written Sample One

In this first example, we will get a GPT-created response to the prompt: “Explain artificial intelligence in simple terms”.

ChatGPT AI text 1

AI content dector 1

Putting this through the detector is a success – 100% written by AI.

AI-Written Sample Two

In the second example, we will get a GPT-created response to the prompt: “Summarize the plot of Harry Potter in 5 sentences”.

ChatGPT AI text 2 AI content dector 2

Another success, though this one with a lower degree of certainty – 71% written by AI.

AI-Written Sample Three

This time, let’s see whether AI’s creative side can be detected. In the third example, we will get a GPT-created response to the prompt: “Write the plot of an episode of Seinfeld where Jerry is explaining artificial intelligence to George and Cramer”.

ChatGPT AI text 3 AI content dector 3

Perfect detection on this result – 100% written by AI.

Human-Written Sample 1

Now we will test the human-written samples. This first one is from our post on the difference between AI and automation.

AI human detector 1

Putting this through the detector is a success – 1% written by AI (though we can assure you it is 0%).

Human-Written Sample 2

The second sample is from another of our posts, The Guide to AI in Graphic Design.

AI human detector 2

This time around, the detector says that it is 2% certain it is written by AI. Passed the test!

Human-Written Sample 3

Lastly, let’s test a recently published Forbes article on the most valuable sports franchise.

AI human detector 3

The last sample is also a success – 1% written by AI.


Overall, Crossplag did an excellent job at detecting AI versus human content. Two out of three of the AI pieces were detected at 99%, and the other was at 71%. Three out of the three pieces that were written by humans were found to be written by humans.

Excellent results.

Can Crossplag be fooled?

Reading Twitter these days, content and SEO professionals are claiming that these AI-content detectors can be “fooled”. There seem to be several ways to fool them, which include:

  • Changing punctuation
  • Making spelling errors
  • Paraphrasing

We took the sample that was found to be 100% artificial intelligence and made a few changes to the text. We changed the punctuation, made two spelling mistakes, and rewrote a few sentences. Let’s see what the results tell us.

AI content detector fooled

It looks like the detector can be fooled, as now it says that it is mainly written by a human. This begs the question: would you consider a text to be AI-written if it was edited by a human? 


With a free account, you can get up to 1,000 words tested. This is not a lot; you would reach this limit with one blog post.

The pricing tiers go up from there:

  • $9.99 for 5,000 words.
  • $149.99 for 100,000 words.
  • Custom pricing for above those levels.

Like a lot of AI tools these days, Crossplag uses a per-word pricing model. There are many content creation tools that are priced lower on a per-word basis. It would be great if prices were lowered or a fixed monthly fee model was put in place.


Our Crossplag review demonstrates that it accurately detects AI content. If you are a business that hires writers, a content manager, or an SEO professional, a solid AI-detection tool now needs to be part of your arsenal. AI-written content is now common, and while it has its uses, many businesses need content that is original, well-researched, and edited.

If you have experience with Crossplag, please write to us! We’d love to hear and incorporate any feedback.
