Frequently asked questions
How does an AI checker work?
An AI checker analyzes patterns in text to check if a human or an artificial intelligence model wrote it. It looks at factors such as word predictability, sentence structure, and stylistic consistency. It compares these elements to commonly seen patterns in AI-generated text and finds the likelihood that the writing is done by an AI.
How to detect AI writing?
You can detect AI writing by providing your text to the Netus AI Detector. The tool will analyze your text and highlight which parts are likely written by AI or a human.
Can ChatGPT be detected?
Yes, ChatGPT-generated text can be detected by AI detection tools. These tools analyze patterns such as word predictability, sentence flow, and repetition that are commonly found in AI-generated writing. However, detection is not always accurate. Advanced models and well-edited text can sometimes be detected as human-written.
How to know if someone used ChatGPT?
Paste the text into an AI detector like NetusAI’s. If many sentences are shown as AI-written (highlighted red), the content is likely from ChatGPT or a similar model. For additional proof, you can compare writing styles or ask the person to explain their work.
How to tell if a student used AI?
Teachers can use an academic AI detector to scan essays and assignments for signs of AI writing. These tools analyze sentence structure, tone, and word predictability to identify possible AI use. However, results should only be seen as indicators, not proof. Educators should not penalize students based only on AI detector results and instead use them as a starting point for discussion or further review.
Does Google Classroom have an AI detector?
No, Google Classroom doesn’t currently have its own AI detector. However, teachers can use third-party tools like NetusAI alongside Google Classroom to check for AI-generated writing.
Why does the AI detector say my writing is AI?
AI detectors can sometimes flag human-written text as AI. The reason can be that your writing style is very predictable, repeats a lot, or it is similar to how AI models generate text. Try paraphrasing your text or use our AI bypasser to make it sound human-like.
Is the AI detector accurate?
The NetusAI writing detector provides highly accurate, sentence-level analysis. But no AI detector is perfect. Results should be seen as possible signs and not absolute proof.
What is the best free AI detector?
NetusAI is one of the best free AI detectors available that lets you run unlimited checks. It works great for teachers, students, editors, and anyone who wants quick, reliable AI detection.
Can AI writing detectors detect paraphrased AI text?
Partially. If AI-generated text is lightly paraphrased, the detector may still identify it as AI. But heavy rewriting using a human writing style can make detection harder.
Does AI detection work for all languages?
Netus AI detector works best for English. For non-English content, results may be less precise, so treat them as a general indication.
Can I use the Netus AI detector on Google Docs?
Yes. Copy and paste your Google Docs content into our Google Doc AI detector on the NetusAI site. It will highlight which sentences are likely AI-generated. You can also use our Google Docs extension for detecting AI writing and humanizing text. Get the Google Docs extension at Netus AI Paraphrasing Tool
Who can use the AI writing detection software?
Anyone from teachers, students, content creators, and researchers. The Netus AI detector is completely free and unlimited for academic and professional use.
Does NetusAI save the provided text or use it for training?
No, your uploaded text is never saved, used for training, or shared with anyone. Your text stays private and secure.
Is NetusAI’s AI detector free to use?
Yes, it’s 100% free. Unlike most detectors, the NetusAI writing detector allows unlimited checks, even on the free plan.
