We Tested the 10 Best AI Detection Tools & Checkers in 2024

There are two sides to the increasingly widespread use of artificial intelligence (AI) in content creation. On one hand, AI is like a wizard that creates quality content in the blink of an eye, saving you tons of time you can invest in other valuable projects. But it’s not all rainbows and butterflies—generating content with AI has its flaws.

Besides being potentially unethical, AI-generated content can be unreliable and flat-out inaccurate.

As AI tools become more advanced, identifying the content created by them gets more and more challenging. This is where AI detection tools come in—they analyze texts and images to discover whether they were created by a human or AI. 🕵️

In this article, we’ll introduce you to the 10 best AI content detectors on the market to help you distinguish between human- and AI-generated content.

What Is AI Detection Software?

An AI detection tool analyzes content to identify trends and patterns that qualify it as human- or AI-generated. When analyzing texts, AI content detectors look for a lack of depth and creativity, repetition of certain words and phrases, specific sentence lengths, or inaccurate or outdated info.

In the case of images or videos, AI detection tools scan elements like objects, poses, or written characters to determine their origin. 🔎

The tools used for AI detection are backed by powerful technology, but it’s important to mention they aren’t always accurate. They can make a mistake, so you shouldn’t jump the gun and trust a tool blindly.

How to choose the best AI detection checker for your needs

There are plenty of AI-detection fish in the sea—how do you catch a quality one? If you want a tool that hits the sweet spot between functionality, ease of use, and reliability, look for the following characteristics:

  1. Multiple language model support: It should be able to pick up on AI-generated text created in GPT-3, GPT-4, Bard, Claude, and other models
  2. Accuracy: The right AI detector should have minimal false positives and negatives and offer somewhat reliable results
  3. Scalability: It should be able to analyze large data items without compromising accuracy
  4. Customizability: The AI detector should let you customize the analysis process to focus on particular criteria that align with your needs
  5. Reporting options: The AI content detector should provide an overview of your analysis history and allow you to identify trends that could potentially fuel the improvement of your content
  6. Cross-platform compatibility: It should work equally well on multiple operating systems and devices

Based on GPT-2 technology, the tool analyzes every word to identify how likely AI would predict it. It does so by focusing on the context before the word in question and the probability that AI would generate a specific sequence of words.

So, if GLTR estimates that AI tools often generate the word you’re interested in and the word before it together, it will flag it.

If the word you’re analyzing is within the top 10 AI predictions, GLTR will color it green. For the top 100 predictions, you’ll see the color yellow, and for the top 1,000 predictions, the word will be red. Everything above 1,000 is violet.

Simply put, if a text is mostly green, there’s a high chance AI generated it.

  • Offers an in-depth text analysis in its AI writing tools
