Get startedFrequently asked questions
How accurate is your AI content detector?
PaperWriter's AI content detection tool provides an estimate of whether the content was AI-generated. While we strive for high accuracy, we can't guarantee that the score will be сompletely precise. At the same time, our tech has a low false positivity rate, which means it can recognize which parts of the text were written by a human and which by AI. It catches rewritten, plagiarized, and polished AI content, too.
How does the AI checker work?
The AI checker analyzes texts and uses advanced algorithms to recognize patterns typical of machine-created content. It spots things like repetitive elements, unnatural wording, and overly similar sentence structure. Then, the technology compares the content against millions of genuine human texts, ensuring high accuracy in detecting AI-generated phrases and sentences.
Can I use AI detection for academic and work-related content?
Yes, absolutely! Our tool is perfect for checking your content, whether it's an essay, blog post, news article, or report. It detects AI-generated elements almost instantly and with high accuracy. It is an easy, stress-free way of ensuring your text is authentic and up to ethical standards, no matter its purpose.
Does your tool support languages other than English?
No. At the time, our tool is available only in English. Our main focus is our software and precise, instant AI content detection. However, we're looking forward to adding other languages in the future. Please stay tuned for further updates on our advanced detection tool!
What types of AI-generated content can your detector identify?
Our AI detector tool identifies content generated by all the most popular platforms, including ChatGPT, Claude, and Gemini. It also catches rephrased or partially AI-generated text, even if mixed with genuinely handwritten content, ensuring precise scores every time. No matter how small or discreet the AI is, the PaperWriter detector will easily spot it.
Is there a maximum or minimum word limit?
Yes. Our AI content detector allows you to analyze from 50 to 3000 words per scan. If your text is longer, just break it into two or more parts and analyze them separately. We have set these limits to ensure higher accuracy, as shorter texts usually provide more precision.
Is the AI detector free to use?
Yes! Our AI detector is 100% free for anyone who needs to check their texts — no registration or subscription needed. To get an accurate AI score, just paste your content into the tool and receive your results in no time. If your text exceeds the 3000-word limit, you can break it down into smaller parts.
How do you protect my privacy?
At PaperWriter, we take your privacy seriously. Our AI detector catches AI-generated content while ensuring your information is safe at all times. It uses industry-level encryption for maximum security. On top of that, we follow a strict Privacy Policy, protecting any data you share with us.
