AI writing tools are popping up everywhere, and so are AI detectors. The fact is that many writers or marketers are on their way to finding the most accurate detection tools to assist their work. So, if you’re here, it’s easy to understand why.
Copyleaks is among the most popular options in the market. However, is it as good as it’s known? This Copyleaks AI review will help you break down how it works, where it shines, and where it falls short, helping you make a better decision.
Let’s explore!
Copyleaks AI for Checking Content Originality
Copyleaks AI is a platform that helps you find AI-generated and plagiarized content. Besides, it has developed other solutions for checking code plagiarism, writing assistance, and integrations with Google Docs and various Learning Management Systems (LMS). In short, this platform is a favorite for those working in education and publishing because it somehow helps to keep content authentic and trustworthy.
Well, unlike other detectors, Copyleaks evaluates both the likelihood of AI-generated patterns and the presence of human writing signals, making its approach more balanced compared to tools that rely solely on AI fingerprints. Accuracy? While the platform claims a low false positive rate of only 0.2%, its reliability has still been a topic of discussion among many users.
To help you get a clearer insight, let’s do a small test.
First, we asked ChatGPT to generate a random text for us.
Using ChatGPT to Generate a Random Text
Then, we paste it into the Copyleaks’ AI detection box. In a matter of seconds, this platform easily points out that the text is 100% AI-generated.

Now, let’s make the game a bit harder. We had QuillBot, a popular paraphrasing tool, rewrite a block of the text before.
Using QuillBot to Paraphrase The AI Text
And we got the rephrased text checked again by Copyleaks. This time, the platform didn’t detect any AI traces. While this shows Copyleaks can miss paraphrased AI content, results may vary depending on how deeply the text is rewritten.
Copyleaks Found No AI in The Rephrased Content
However, despite these occasional missteps, Copyleaks is still considered one of the most reliable AI detectors. The occasional false positive or false negative suggests that while it’s effective, no AI detector is perfect.
Copyleaks AI Review – AI Detection Feature
This is the most widely used feature of Copyleaks. The platform claims an impressive accuracy rate of over 99%, and it works with a variety of AI models like ChatGPT, Gemini, and Claude.
What sets Copyleaks apart from other AI scanners is its unique approach: instead of just looking for signs of AI writing, it focuses on identifying characteristics of human writing. It scans text for the typical patterns and styles that real human writers use.
Besides, the AI Insights tool explains why a piece of text was flagged as AI-generated, giving you valuable insight into AI writing patterns.
Plagiarism Checking Tool of Copyleaks AI
Another key feature of Copyleaks is plagiarism catching. Imagine having access to an extensive database that includes over 16,000 open-access journals, more than 60 trillion websites, and millions of internal documents. That’s exactly what Copyleaks offers!
You want to check the text that is non-English? No worries. One of the advantages of Copyleaks is its cross-language detection, which supports over 30 languages. This makes it perfect for checking documents written in multiple languages without a struggle.
Copyleaks AI Code Detector
Copyleaks detects not only text copies. Unlike other basic names in the market, it can spot cleverly modified or paraphrased code across popular languages like Python, Java, C++, and more. Cool, isn’t it? So, this tool isn’t just for writers; developers and alike can still benefit from it.
One of its standout features is function-level analysis, allowing it to spot subtle similarities even when variable names are changed or comments are added. Codeleaks also addresses the rise of AI-generated code. If it suspects code might have been authored by tools like ChatGPT, it flags it for you. Plus, with licensing compliance checks, you can easily avoid copyright issues when reusing open-source or third-party code.
| PROS | CONS |
| ✅ Advanced AI detection
✅ Codeleaks for source code ✅ Wide language support ✅ Massive search coverage ✅ Flexible integrations |
❌ Limited free usage
❌ Can flag false positives, especially with formal writing ❌ Less effective with paraphrased or humanized AI content |
Copyleaks is good at finding clear AI-generated content, but it has difficulty with text that people have lightly edited or rewritten using tools like QuillBot. This can be frustrating for professionals who need reliable validation, so it might be a good idea to look for other tools that are more accurate or specialized.
Below are three names that you might take into consideration.
Originality AI – Best Copyleaks AI Alternative
Originality AI is a leading tool that’s perfect for SEO writers, publishers, and academic institutions. It stands out for its impressive ability to spot text generated by AI, making it a reliable choice for anyone wanting to ensure their writing is original. This tool does more than just detect AI content; it also helps you assess things like readability, grammar, and originality all at once.
What makes it great:
Winston AI Checking Tool
Winston AI is unique because it can detect not just text-based AI content, but also AI-generated content found in images and handwritten notes. This makes it an excellent pick for teachers, researchers, and institutions dealing with scanned assignments in various formats.
What makes it great:
Undetectable Detection Tool Interface
The last name is perfect for those who need fast results without needing to log in or navigate complicated dashboards. Undetectable AI offers instant AI detection and a “Humanize” feature that rewrites AI-generated text to sound more natural and human-like.
What makes it great:
Ultimately, Copyleaks AI is a powerful tool for educators, marketers, and developers since it helps identify AI-generated and plagiarized content. It’s user-friendly and continually evolving, making it a reliable choice for your content verification needs.
However, it’s always smart to remember that no tool is perfect. So, one of the solutions is to rely on a mix of resources and to self-evaluate for better insights.
