Everything you need to know about AI content detection, our methodology, and how to get the most accurate results.
Our detector achieves 99.2% accuracy across major AI models including GPT-o3, Claude Opus 4.5, and Gemini 2.5 Pro. We use a multi-layered analysis combining perplexity scoring, burstiness analysis, entropy measurement, and neural pattern recognition to deliver industry-leading results.
We detect content from all major language models: OpenAI GPT-o3 and GPT-4o, Anthropic Claude Opus 4.5 and Claude Sonnet, Google Gemini 2.5 Pro, Meta LLaMA 3, Mistral, and many others. Our detection models are updated continuously as new AI systems are released.
AI-generated text exhibits distinct statistical patterns that differ from human writing. We measure perplexity (how predictable the word choices are), burstiness (variation in sentence complexity), entropy (information density), and stylometric features. Human writing tends to be more variable and unpredictable, while AI text follows more uniform statistical distributions.
Yes. Educators worldwide use Pro AI Detector to verify the authenticity of student submissions. Our tool provides detailed sentence-level analysis with confidence scores, making it easy to identify which portions may be AI-generated. We recommend using our results as one component of a comprehensive academic integrity review.
No. We take privacy seriously. Text submitted for analysis is processed in real-time and is not stored on our servers after analysis is complete. We never share submitted content with third parties. See our Privacy Policy for complete details.
For optimal accuracy, we recommend submitting at least 100 words. Shorter texts can still be analyzed but may produce less reliable results due to insufficient statistical data. Longer texts (300+ words) generally yield the highest confidence scores.
Our sentence-level analysis excels at identifying mixed content. Each sentence receives an individual AI probability score, allowing you to pinpoint exactly which sections may be AI-generated. The overall score reflects the weighted average across the entire text.
We are currently developing a REST API for developers and enterprise customers who need to integrate AI detection into their workflows. Contact us to join the API beta waitlist and receive early access when it launches.
