Curious about Grammarly's AI Detector? Let's dive into what it is, how to use it effectively in 2025, explore its features, and see how it stacks up against other AI detection tools.

The AI Detector from Grammarly is a handy tool designed to help you figure out if a piece of writing might have been created by artificial intelligence. It works by looking at your text, breaking it down into smaller parts, and then comparing those parts to common patterns found in AI-generated content. Based on this analysis, it gives you a percentage score that suggests how likely it is that AI wrote it.
Now, it’s important to remember that tools like Grammarly’s AI Detector are really helpful for getting a general idea, but they aren’t foolproof. They can’t definitively say, ‘Yes, this was written by an AI’ or ‘No, this was definitely human.’ That’s why it’s a good idea to use these detection tools as just one part of a bigger picture when you’re trying to understand where your writing came from and how original it is. Grammarly also really stresses the importance of using AI responsibly and is always working to make sure its AI detection models are as fair and unbiased as possible.
Grammarly is the company behind the AI Detector. The folks who founded Grammarly are Alex Shevchenko, Max Lytvyn, and Dmytro Lider. They started Grammarly way back in 2009, and since then, it’s grown into a super popular writing assistant that uses AI to help people write better.
