The Best AI Detectors

The technology is amazing, but it can also be dangerous, presenting new risks and challenges in fields like online publishing and education, where ChatGPT and similar tools may be misused. That’s why AI detectors are becoming increasingly important in today’s world.

In this article, we’ll take a look at the best AI detectors currently available, including free and paid options.

Best AI Detectors: The Top 4

1. Originality.AI

No list of the best AI detectors is complete without Originality.AI. Widely-regarded as the top dog in the AI detection industry, this tool has some of the best success rates and most impressive technology.

Most other AI detectors simply can’t keep up with Originality.AI. It’s one of the most reliable detector tools to use for any kind of text, from student essays to online blog posts, and everything in between.

However, there is one downside to this tool: the cost. To use Originality.AI, you have to buy credits. Each credit costs 1 cent and can be exchanged for a scan of 100 words. It’s not too expensive in small doses, but if you have long texts to check, the costs quickly add up.


  • Scans text with a high degree of accuracy
  • No word or character restrictions to worry about
  • Trusted by businesses around the world


  • Can be expensive when scanning multiple long texts

2. GPTZero

Boasting a big user-base and rave reviews, GPTZero is another popular AI detector to try out. One of the first big detector tools to be released, it’s proven useful for educators and other professionals across the globe, particularly since ChatGPT hit the headlines in late 2022.

GPTZero is able to scan for various AI bots and writing platforms, and can even tell if someone has started off with an AI text and then made a few alterations to it. Like any tool, it’s not 100% accurate all of the time, but it’s still reliable and easy to work with.

How about cost? Well, GPTZero is available in a free version for people who simply want to test it out or scan small amounts of text (up to 5,000 characters). If you need full access, you’ll have to pay, with prices starting at $9.99 per month.


  • A popular and proven AI detector
  • Free to test out
  • Multiple payment plans and regular discounts


  • Can’t scan more than 5,000 characters as a free user

3. Copyleaks

But what makes Copyleaks so special for business users? Well, it’s exceptionally accurate, with a reported 99% reliability rating. It also offers both LMS and API integration. As such, you can set it up on your office or business network without any issues.

Looking for the best AI detector for the educational sector? If so, Winston AI might just be the one you need. It comes with handy reporting features that teachers and university professors might like to try.

With Winston AI, you create individual “projects” for every document you want to scan. You can paste or upload the text, and the platform will give you a 1-100 percentage score, based on how human or AI-like the text appears.

Then, you get an individual report for each project, which you can save that or even print it off. This could be handy for teachers who want to stop students relying on AI bots to handle essays on their behalf. Winston is free to try, with premium plans from $14 per month.

Teachers, writers, content creators, agencies, marketing professionals, and many other people can all make use of AI detectors to scan for AI-made content.

How accurate are AI detectors?

It depends. Some AI detectors are incredibly accurate, but even the best tools make mistakes from time to time. With AI technology evolving rapidly, reliability levels can change from one day to the next. This is still quite a new industry, so we have to hope that AI detection will only improve as time goes by.

What should I look for in AI detector software?

With so many AI detectors out there, it’s not always easy to know which one to choose. For starters, we recommend focusing on tools that are either free or within your budget. Make sure to find a detector that can cope with the length of articles or pieces of text you wish to scan, and look for one with a high accuracy rating to avoid false positives.
