AI Content Detector – Identify Human vs AI-Generated Text with Accuracy

The rapid growth of generative AI in education, business communication, recruitment, and digital media has created a real need for reliable tools to verify text authenticity. Our advanced AI content detector helps you quickly determine whether a document was written by a human, generated by AI, or contains a mix of both. By analyzing the entire text or zooming in on sentence-level patterns, the tool provides a clear probability score that indicates the likely origin of your content and supports better decisions about originality and credibility.

Trained on extensive datasets of human-written and AI-generated content, our detection model has been fine-tuned to recognize outputs from today’s most advanced large language models, including GPT-5, Claude, Gemini, LLaMA 2, and Mistral. This diverse training allows the system to detect even subtle linguistic patterns and stylistic signatures typical of generative models — providing accurate results across academic papers, business documents, and long-form content.

It is important to note that AI detection should be viewed as a valuable indicator rather than a final verdict. The tool delivers the highest accuracy when full documents are uploaded instead of short excerpts. For the most precise evaluation of originality and authorship, we recommend checking complete texts, ensuring a deeper understanding of whether your content is genuinely human-written or influenced by AI.
