Top 11 Best AI Detectors Of 2024 – Reviewed & Tested

Just like the coin, the increasingly widespread use of AI (Artificial intelligence) in content creation has two sides. One is that AI is like a magical tool that can create quality content with just one click to save you tons of time that you can invest in other valuable projects. But, on the other hand, it is not all butterflies and rainbows; generating AI content has its own flaws.

Along with being potentially unethical, content generated by AI can also be unreliable and flat-out inaccurate. 

As AI tools are becoming moe advanced, identifying the content created by them gets very challenging. This is where AI detection tools come in handy. They help analyze texts and images and discover whether they were created by AI or humans. 

Today, in this article, I have listed the best AI content detector tools that are available on the market.

1. GLTR

Rating – 4.8 / 5

Giant Language Model Test Room (GLTR) is an AI detection tool developed by Watson AI Lab and HarvardNLP. It helps in conducting forensic analysis of a text and determining whether it is generated by humans or AI. 

GLTR uses GPT-2 technology, and this means the tool analyses every word to identify how likely AI would be to predict it. This is done by focusing on the context before the word in question and the probability that AI generates a particular sequence of words. 

So if GLTR estimates that AI tools often use the word you are interested in and the word before it together, then it will flag it. 

Therefore, if a particular word is within the top 10 GLTR predictions, the tool will color it green. If it is in the top 100 predictions, the tool will color it yellow, and for the top 1,000 predictions, GLTR will color is red. And Everything above 1,000 is violet. 

In simple words, if the text is mostly red, there is a high chance that it is generated by AI. 

Features – 

• In-depth Text Analysis: GLTR conducts a detailed analysis of the text to identify patterns and characteristics commonly associated with AI-generated content.
• Color-coded Text: The tool color-codes the text to highlight sections that indicate the potential use of AI, making it easier for users to identify suspicious segments.
• Word Position Assessment: GLTR assesses the position of words within the text to determine if the language and structure resemble those generated by AI models.
• Free to Use: GLTR was available for free, allowing users to access its features without cost.

My Experience With GLTR –

Using GLTR was quite the experience for me, and I must say, it’s pretty snappy! The results came up in no time, and the whole interface was super easy to navigate. I appreciated that, considering I’m not exactly a tech whiz.

Now, here’s the kicker – understanding the analysis took me a beat. It’s not like rocket science, but it’s not even a breeze. It might take a while to get the hang of it.

My Experience With AI Text Classifier (Open AI) –

Testing OpenAI AI Text Classifier has been an interesting experience, with a few bumps in the road. I was hoping for an easy ride in detecting AI-generated content.

To my surprise, the results weren’t as spot-on as I expected. Despite giving the tool the content that is “100% human,” the AI insisted it was machine-generated. The reasoning provided was quite puzzling – apparently, the content was flagged due to the content is packed with information – and the tone was formal and neutral.

But isn’t it perfectly reasonable for a human to write in a formal manner and deliver information-rich content? I found myself wondering why the tool seemed to favor a more laid-back, casual style over a more polished and informative approach.

It felt like the tool had a preference for a certain flavor of language that, in my opinion, doesn’t necessarily scream “human.”

Despite this hiccup, I’m intrigued to see how the OpenAI AI Text Classifier evolves and improves over time. I’m hoping that future updates will better understand the nuances of human expression.
