Why Choose a GPTZero Alternative?

GPTZero assesses content complexity and variety to deliver an AI probability score. While this detection model can identify AI-generated text, its flaw is it isn't as effective at accurately classifying human-written text.

Simply put, if the author’s writing style goes against GPTZero’s unpredictability model, it could be inaccurately flagged as AI text.

To back this up, we decided to test out GPTZero by scanning a piece of text we wrote personally. As you can see, the platform returned a staggering 82% AI probability score.


Aside from that, GPTZero presented other equally frustrating drawbacks. For one, plagiarism scanning is only available on its premium plans.

Moreover, it doesn’t offer AI detection in multiple languages. Plus, the platform fails to provide unlimited word counts on any of its pricing plans. This can be inconvenient for handling bulk content.

Luckily, the AI detectors on this list can offer more reliable performance and do well to accommodate varying user needs more effectively.


As we’ve established, GPTZero is not a perfect AI detector by any means. It has several failings, which is where the 10 best GPTZero alternatives on this list come into play. Each of them can help you detect AI content with ease. However, we strongly recommend HIX Bypass because it is the most accurate and comprehensive solution out there.
