GLTR is my go-to for spotting AI content. It highlights each word to see if it's like AI text. Powered by GPT-2, it's great at understanding human-like writing.

Using GLTR is easy. I input text, and it quickly shows any AI similarities. This helps me catch any AI-written content easily. This ensures a fair assessment.

Process of Reviewing 

When we looked at the GLTR ai detector closely, we followed a structure to test methodology how good it is at finding both human-written and AI-generated content.

Step 1 – Initial Assessment

I began by testing the GLTR AI detector with both human and AI writing to see how well it could spot the differences. This step was crucial to gauge its accuracy.

Step 2 – Checking Accuracy

Then, I used various methods to test if the GLTR could mistakenly label AI content as human-made. This part was key to seeing how reliable GLTR is and where it might get things wrong. 

Step 3 – Experimenting with Strategies

Finally, I tried different ways to see if GLTR AI detection could wrongly make people think AI-made content was actually written by someone. This showed me where GLTR works well and where it struggles.

Checking How Well GLTR Works

This tool takes a different approach compared to many AI content detection tools. It doesn't rely on a probability format. This tool highlights the word according to the result.

Now, I’m going to check the accuracy of the GLTR ai checker. I head into ChatGPT and ask to generate a paragraph on “storytelling”


ChatGPT provides me with results instantly. Now, let's see how well GLTR ai detector did in this test and it finds mistakes in AI content.


This is the final outcome of the GLTR detector results. Red color shows that the content is generated by an AI tool. 

Now I have pasted human-written content into this AI checker. Let's see if it gives the same results or not.

It can see the differences in how people write and how AI generates content. This time GLTR ai detection provides different results. Most of the content is in Green color which ensures that the content is genuine and unique. 


GLTR ai detector automatically identifies generated text using forensic analysis techniques. Its main key features are:

  • It uses a special language tool called GPT-2.
  • The histogram feature shows you a picture of the various words used in a piece of writing.
  • GLTR's main features involve using forensic text analysis to highlight specific words that may be generated by AI.

How Much Does GLTR Cost?

Pros and Cons 

Let’s find pros and cons of the GLTR AI checker tool.


  • Words in different colors make it easy to understand.
  • Use tables and pictures to show why something is true.
  • Check complex words in GRE texts to find content made by computers.
  • Save money.


  • Might be a bit tricky to understand at first.
  • It's not very good for the latest technologies.

GLTR AI Checker is Best for?

The GLTR detector is great for researchers and developers. It gives them a set of tools, data, and tests for studying language in AI. Instead of being easy for everyday users, it's more about helping experts improve AI models together.

It's designed to boost long-term capabilities rather than just make things easy for users. Some users need to show their AI content in percentage form. For them, there is also another best option which is the free AI Checker. Which is free and easy to use for all users.
