Is ZeroGPT the Best AI-Generated Content Detector? Features, Comparison & Alternative

May 29, 202539 views

I can’t even tell you the number of emails I’ve gotten about AI-written material. Educators get frustrated when the AI detection software they’re using can’t pick up on AI-written content, while students feel wronged whenever their original content is flagged as AI.

ZeroGPT has been making rounds online as an AI-detection tool. Its popularity hinges on the fact that it’s free, but is it reliable? Or is this a case of “you get what you pay for”? Keep reading my ZeroGPT review to find out.

ZeroGPT’s Detection Mechanisms and Features

I’m sure you’re probably wondering, “How do these tools even recognize AI writing when most humans can’t even tell the difference?”. One word: ‘patterns’. ZeroGPT uses advanced algorithms to identify AI-generated text by analyzing perplexity, burstiness, and linguistic patterns.

AI tools are trained to recognize structure, word choices, and sentence length that the AI model was originally trained to replicate, meaning how predictable the structure and word choices are for the AI itself.

However, is the system perfect? End-users will tell you many instances where AI text bypassed checks while original content was flagged as AI by software.

First impressions for my ZeroGPT review? The interface is user-friendly. I didn’t need to make an account to use it, and the analysis took maybe a couple of seconds, which is a huge plus.

While using ZeroGPT, I tested several bodies of text, written by myself and an AI writing tool, respectively. As a detection tool, I’d say it’s decent for the most part, but it did flag some of the content I had written myself as AI. Something you don’t want in a detection software.

There have been instances of false positives that users have reported on Reddit. Even though that wasn’t my experience with ZeroGPT, it is important to acknowledge these failures because AI itself isn’t perfect yet; expecting a perfect result from any tool wouldn’t be fair.

That being said, third-party evaluation or a comparative benchmark is essential before relying on ZeroGPT for academic or professional use. To summarize, here’s a list of Pros and Cons of ZeroGPT.

Pros

  • User-friendly interface.

  • No account needed.

  • Super fast analysis.

  • Most features are free to use.

Cons

  • Has accuracy issues.

  • No Transparency on detection methods.

  • Lacks document history.

  • Has a word limit depending on what premium plan you have.

How to Use ZeroGPT to Detect Contents

One of the most appealing features, at least to me, was how simple ZeroGPT is to use. It doesn’t require you to make an account first. It doesn’t require you to enter your credit card information because it’s free.

The tool itself guides you on how to use it, just follow the on-screen instructions and you’ll get the hang of it pretty quickly, but if you need a step-by-step guide, here’s how to do it.

Step 1: Since ZeroGPT is an online tool, you will need your browser to navigate to ZeroGPT.

Step 2: On the screen, you’ll see a box with the instruction “Paste your text here”. Go ahead and paste your text in the space provided.

Step 3: At the bottom of the box, you’ll find a “Detect Text” button. Click it.

Step 4: Wait a couple of seconds for the AI to analyze your text. It will give you a percentage reflecting how much AI-generated text it found in the document.

Step 5: You can get a complete analysis of what parts the AI believes to be AI-generated right underneath the percentage. Under that, you’ll find a button that says “Humanize Text”. You can make your text more human-sounding with just a click.

Best Alternatives to ZeroChatGPT

Is ZeroGPT the best AI-detection tool I’ve ever tried? No. It is fairly simple to use, it is great for people on a budget, but at the same time, there are tools out there that are a better alternative. Here are a couple of my favorite AI tools.

Toolsmart: Free Undetectable AI for ChatGPT and More

At the top of the list, we have Toolsmart AI Rewriter. An all-in-one AI tool that does more than just AI detection, but that’s not what we’re here to judge. The most important factor to look at right now is how it fares as a detection tool. Here is a complete breakdown of what it has to offer.

Features

  • Paraphrasing tools generate very human-like text.

  • It hosts a number of modes, namely, academic, formal, and casual.

  • It offers full text customization for your convenience.

  • Excellent AI-detection.

  • OVER 50+ FREE AI TOOLS!

Functions

  • The AI writing is practically undetectable.

  • The tool also offers plagiarism protection so that plagiarism detectors such as Turnitin, Scribbr, or Copyleaks don’t flag your content.

  • The text can be simplified for better understanding or made conversational for your readers.

Pros

  • Toolsmart is 100% free and requires no signup like ZeroGPT, but it works exponentially better.

  • Offers bypassing for AI detectors and plagiarism checkers.

  • The output it generates is entirely customizable. You can change the tone or the wording, whatever you like.

Cons

  • It’s a relatively new AI tool compared to the ones already in circulation.

It’s not as well-known, which means it has fewer reviews as well.

Justdone AI: AI Text Humanizer

Next up, we have JustDone AI. A lot of you may have already come across this one or used it in passing. Users prefer it for generating content that doesn’t come off as “robot-like” or “monotone”. It does a very good job of replicating human speech. Here’s my analysis of ZeroGPT vs JustDone AI.

Features

  • It’s mainly focused on turning AI text into more “human-sounding” language

  • great for students and marketers for ‘personable’ content.

Functions

  • JustDone AI is mainly known for its Humanizer tool.

  • It also offers enhancements, such as making your content more SEO compatible.

Pros

  • Its Humanizer tool generates text that’s pretty good at bypassing AI detection.

  • Offers multiple rewriting levels that you can use as many times as needed.

Cons

  • Some of the features aren’t free, they require a premium.

  • Toolsmart offers more paraphrasing.

That is why JustDone is second on the list.

Grammarly

Probably the most well-known tool out there is Grammarly. You’ve probably seen countless YouTube ads for this one. Even though most of you are probably aware of what Grammarly has to offer, let's go over some of the features anyway. Let me explain why it's third on my list.

Features

  • As the name states, it’s mainly for Grammar and tone detection.

  • It does have an AI-detector as part of its premium tools.

Functions

  • A lot of educators probably have Grammarly as their tool of choice for Plagiarism checking.

  • Students and office workers, on the other hand, use it for writing improvement.

Pros

  • Grammarly wins me over with its user interface.

  • It is a great tool for grammar enhancement.

A great tool for grammar checks, which is to be expected since that was its primary function.

Cons

  • It is by far the most expensive of all the AI tools.

  • AI detection is not its core function, which means it’s not all that great at it.

Grammarly premium costs a pretty penny, one that not a lot of people are willing to pay, so they stick to the free version, which has very limited tools.

Quillbot: Your Complete Writing Solution

Another well-known AI tool. Probably not at the same popularity as Grammarly but still up there. Quillbot has very limited features but it's still a great tool to use in a pinch. Here are observations about this tool.

Features

  • The main purpose of this tool, and something many students and creators use it for, is paraphrasing and summarizing.

  • It also restructures your sentences if they don’t agree with the tone you want. The result might not be exactly what you’re looking for, but you get multiple tries until you get to a sentence you’re happy with.

Functions

  • The main function, again, is AI rewriting.

  • It also offers moderate grammar checking.

Pros

  • Academically speaking, the rephrased sentences work well.

  • You can customize the rewriting.

Cons

  • It has a word limit of 125 words. If you have massive amounts of text, do it in very small sections.

  • It wasn’t meant for AI detection, which is the main feature we’re looking for in this ZeroGPT review.

It would not be a stretch to say that AI-generated content has largely taken over the writing sphere. Given how widespread it is, you need a powerful detection tool and a rewriting tool to bypass detection. Either way, ZeroGPT falls short in the accuracy department. JustDone AI, Grammarly, and Quillbot are good alternatives, but even they have their limitations.
