Innovative Business Ideas and Brainstorming

AI-generated content isn’t some far-off future anymore. It’s already part of everyday life. Blog posts, student papers, product descriptions, emails — you never really know if the words you’re reading came from a person or from ChatGPT. And that’s exactly the problem. AI tools write fast, clear, and often sound pretty natural. So how do you tell if a text was written by a human — or by a machine just really good at sounding like one?

That’s where AI detectors come in. There are plenty of tools out there promising to spot AI-written content. But which of them actually work? To find out, I tested five of the most popular ai detector tools to see how well they handle ChatGPT-generated text — and which one you can really trust.

One tool I was especially curious about was AI detector by Smodin. It’s often mentioned for its accuracy, so I wanted to see if it really lives up to the hype. In this article, I’ll show you what each tool offers, how they work, and — most importantly — which one actually delivers results.

Smodin

Smodin is one of the most straightforward AI detectors I’ve tried. The interface feels clean, modern, and — most importantly — easy to navigate. Whether you paste your text or upload a file, the process is super quick. No extra steps, no confusion.

What really sets Smodin apart is how detailed and clear its results are. It doesn’t just give you a simple AI or human label. It shows the percentage of AI vs human content, highlights specific parts of the text that look suspicious, and provides a confidence score.

Another big plus — Smodin supports over 100 languages, which is rare for tools like this. And in terms of accuracy? Very solid. It handled both obvious and more natural-looking AI texts really well. If you’re looking for an ai detector that’s simple, clear, and highly accurate, this one definitely deserves attention.

Undetectable AI

Undetectable AI works a bit differently compared to most detectors. What makes it unique is that it doesn’t just check your text on its own — it also shows how your content might look when scanned by other popular detectors. In a way, it feels like running your text through several tools at once.

The interface is clean and easy to navigate, and what’s especially nice — it can handle large pieces of text without any problem. That makes it a good fit for checking longer articles or documents. The tool highlights sentences it sees as AI-generated and gives an overall verdict about how likely it thinks the content was written by AI. It confidently identified clear AI-generated content but also handled more natural, human-like writing without much trouble.

QuillBot

QuillBot is mostly known for its rewriting tools, but it also offers an AI detector — and the experience is pretty straightforward. The interface is clean, simple, and easy to figure out even if you’re using it for the first time.

You can paste your text or upload a file, and the tool will quickly show you the result. One of the nice features here is that QuillBot highlights AI-generated sentences and marks how confident it is about each of them.

As for accuracy, it did better than I expected. QuillBot managed to catch a good portion of the AI-generated content and handled mixed texts reasonably well. It’s a solid option if you want a simple, free tool for quick checks — though not the absolute leader in precision.

Scribbr

Scribbr keeps things very simple, and that’s exactly what makes it easy to use. The interface is minimal, without too many buttons or distractions. It supports just a few languages, but for quick checks in English, it works smoothly.

The detector gives you a basic AI vs human percentage and highlights the suspected AI-generated parts of the text. Everything looks clean and easy to read, which is a big plus if you’re not a fan of overly technical tools.

It spotted obvious AI-generated content without much trouble and stayed consistent when working with different styles of text. It might not have as many extra features as other tools, but it gets the job done nicely when you need a fast and clear answer.

GPTZero

GPTZero is probably one of the most well-known AI detectors around. The interface looks modern, but it can feel a little overloaded with details — especially if you just want a simple answer.

The free version allows shorter checks and shows the overall percentage of AI content in the text. The only catch is that GPTZero highlights AI-generated sentences only if you create an account — not everyone will love that.

The tool easily recognized human-written content, but with fully AI-generated texts, the results were less convincing. Sometimes it missed obvious AI patterns, especially in simpler texts. Still, GPTZero stays a popular choice for basic checks — especially if you like having extra details and in-depth reports.
