Copyleaks AI Content Detector Review: Does It Detect AI?


Copyleaks AI is a tool that finds out if a piece of writing was made by a AI.

Lately, we’ve seen many tools that use AI to write things like emails or blogs. Sometimes, it’s tough to know if a human or a machine wrote something.

Because of this, people worry about writings made by Artificial Intelligence. For example, Google doesn’t like them because they often don’t have new ideas. Simply, they don’t give readers or search engines anything special.

Some companies, seeing this problem, made tools to detect AI-made writings. These tools are pretty good at telling if a machine or a human wrote something.

We took a close look at the Copyleaks AI tool detection. We tested it with writings from both humans and Chat GPT.

How Does the Copyleaks AI Tool Work?

Copyleaks AI is like a detective that can tell if a AI or a human wrote something.

Here’s how to use it:

  • Type or paste your writing into the Copyleaks tool.
  • Click to scan.
  • Look at the score to see if it’s original or not.

But with so many good AI writings out there, can this tool really tell the difference? Let’s try it out and see!

Testing Time

We wanted to see how good Copyleaks AI is:

  • 10 articles from my blog (written by me).
  • 10 pieces written by an AI program named ChatGPT.

First, let’s see how it does with my articles.

Trying It with My Articles

We put parts of my blog writings into the Copyleaks tool. After each test, Netus AI noted if it guessed right or wrong.

The perfect result? The tool should know that a person (me) wrote all these articles.

Is the Copyleaks AI Tool Really Reliable?

Using just 10 writing samples to test isn’t a lot. For better accuracy, we would need to test way more samples.

From what we’ve seen, though, the AI detector does get things wrong sometimes. So, you can’t fully trust CopyLeaks AI every time you get a result.

However, not everyone needs a perfect tool. Some folks just want to use the AI detector to make their AI-written content look more like a person wrote it.

Testing AI-Written Articles

A lot of writers use tools like this to fix their AI generated writings so they seem more human-like.

That’s why we should really check how well CopyLeaks AI works with articles written by AI.

So, Netus AI tried the tool with 10 AI writings. Here’s what happened.

How Good is Copyleaks at Spotting ChatGPT Writings?

If you write with ChatGPT, there’s a half chance Copyleaks AI will catch it. But, we only tried 10 writings. For a better idea, we should test more.

But if it gets it wrong 5 times out of 10, it seems the tool isn’t super reliable.

Can We Avoid Copyleaks AI Detection?

Let’s have some fun! We’ll take a piece written by an AI, change it a little, and see if Copyleaks gets fooled. Let’s give it a try!

Test 1: What Happens If We Drop a Comma? ➡️ In short: The tool got tricked by just removing one comma.

Netus AI tried out some AI writing checkers before, and a small change can easily confuse them. For instance, make a tiny mistake or change one thing, and suddenly the checker thinks it’s human writing.

That’s not good. One little edit shouldn’t make such a big difference.

So, let’s see what happens if we lose the comma after “Additionally”:

Making a small change By just taking out that comma, the tool thought an AI’s content was written by a person.

Test 2: Let’s Try a Mistake ➡️ Quick summary: Skipping one letter made the tool see it differently.

What if we miss a single letter in the AI Generated text?

Just drop the “i” from the word “their”:

Oops, a typo! Guess what? The tool now thinks a person wrote it, not an AI.

Test 3: Changing Words with AI

In short: Using AI to change the writing made the detector mess up.

Let’s see what happens when we let an AI tool, Quillbot, change the AI’s writing. Quillbot does this fast, in just a couple of seconds.

Mixing up the words The changed text looks okay, but some parts really sound like a robot wrote them. You might even guess that without using a tool.

So, what happens when we check this new version with CopyLeaks AI? Let’s find out.

What’s Good

  • It’s Free: Anyone can use CopyLeaks AI without paying. Plus, it’s easy to use.
  • Finds Human Writing: It’s pretty good at telling if a person wrote something, but not always right.

What’s Not Good

  • Misses AI Writing: It doesn’t catch AI writing well. In my test, it missed half.
  • Can Be Fooled: Change a letter, and it gets confused.

My Overall Take CopyLeaks AI isn’t great with newer AI writings, like ones from ChatGPT.

A lot of AI writing tools today use ChatGPT, and CopyLeaks misses them.

We’ve tried other checkers, and none are perfect. Some are right 90% of the time, but that’s not enough.

To wrap it up, maybe try a different tool, like, for better results.

Copyleaks AI Content Detection: A Simple Review
