AI Content Detector

AI Content Detector is a professional tool that analyzes text to assess whether it was likely produced by artificial intelligence.

The tool helps users evaluate the originality and authenticity of text, commonly used in education, content production, publishing and other contexts that require content review.

The tool typically supports detection of content generated by a range of mainstream AI models, including but not limited to GPT series, Gemini, Claude and other common models.

Detection is not 100% accurate and false positives or negatives can occur. Mixed-content or AI text that has been heavily edited by humans is harder to identify. Performance may also vary across languages and text types.

The tool generally supports long-form analysis; exact character or file size limits depend on the product version—please check the specific plan documentation.

Results usually include a quantitative likelihood score, highlighted passages suspected of being AI-generated, and a detailed detection report.

You can typically paste text directly, and many versions also accept uploads of common document formats such as .doc, .docx and .pdf.

Many detection tools tend to perform better on English than on Chinese; accuracy for Chinese content can vary depending on the tool and the type of text.

Educators can use it as an auxiliary tool to review student submissions—essays, reports and assignments—to help uphold academic integrity, while keeping in mind that it should complement, not replace, human judgment.
