If you’ve used AI to write any public or academic content, you need to use a ChatGPT plagiarism checker.

There is a lot of focus on detecting AI-generated content.

But you may not realize that AI models like ChatGPT can often include plagiarized writing from existing sources.

These will set off plagiarism detectors like TurnItIn or even less sophisticated methods like simply googling your text.

In this post, I will share the best option for checking your ChatGPT content for plagiarism and provide free alternatives for those on a budget.

Let’s dive in!

TLDR: My recommended ChatGPT plagiarism detector that I personally use is Grammarly.

I tried everything, and it’s not even close.

I’m actually confused as to why there is so little competition.

Try out Grammarly’s free plagiarism detector.

What Is A ChatGPT Plagiarism Checker

A ChatGPT plagiarism checker is any app that scans your AI-generated content to see if any of the text matches existing writing online.

Think of a plagiarism detector as an advanced Google search that scours the entire web for any portions of your text that have been written previously.

Often, plagiarism detectors pick up little phrases that have appeared elsewhere online.

For example, in one of my last posts, I wrote a phrase about an app being available for Windows and Mac.

Unsurprisingly, this exact phrase has appeared online many times before.

In this instance, I ignore the plagiarism checker.

But it’s good to know how sensitive a good plagiarism tool can be.

Why Use A ChatGPT Plagiarism Checker

ChatGPT is capable of generating 100% unique, never written before, content.

However, you need to remember that AI models like GPT are trained on tons of previously written text, such as books, websites, and research papers.

So it’s entirely possible for ChatGPT to provide a response that includes plagiarized content.

It actually happens quite often.

Not to be confused with an AI detector, a plagiarism checker is even more important.

This is because there still isn’t really a rock-solid method to detect AI content.

On the other hand, plagiarism is incredibly easy to identify.

And the consequences of plagiarism are generally much higher.

It’s particularly critical in an academic setting, where even one instance of turning in a plagiarized assignment can lead to expulsion from the program.

Best ChatGPT Plagiarism Checker

The best ChatGPT plagiarism checker, hands down, is Grammarly.

Grammarly has a limited free version that you can test out.

But unfortunately, the full unlimited version is paid.

I use this tool personally and was reluctant to purchase it at first.

Ultimately, it was an easy decision when weighing the cost of accidentally plagiarizing someone else’s content.

When you are logged into Grammarly, you can access the plagiarism checker by clicking the plagiarism button on the bottom right.

This will scan over 16 billion pages to see if any of your text has appeared before.

Additionally, the Grammarly paraphrase feature is a great way to avoid plagiarism issues.

This is particularly important if you need a ChatGPT rewriter solution.

Free ChatGPT Plagiarism Checker

I found a few free ChatGPT plagiarism checkers if Grammarly is out of your budget.

A Research Guide (Tool)

This tool is a good option for checking essays for obvious instances of plagiarism.

There is a 20,000-character limit, which is around 3,000 to 4,000 words.

Google Search

If you need more clarification on a particular sentence or phrase, copy and paste it into a Google search.

This method only works for small amounts of text, but this is an excellent way to see if the writing appears anywhere else online for shorter snippets.

FAQ

How to avoid plagiarism from ChatGPT?

To avoid plagiarism from ChatGPT, run your AI-generated text through a plagiarism detector like Grammarly.
