17 powerful features
Everything you need to detect AI-generated content with industry-leading accuracy.
Multi-Model Detection
Trained on outputs from GPT-4, Claude, Gemini, Llama, and more. We detect the statistical patterns unique to each model family.
Instant Results
Get your detection score in under 2 seconds. No waiting, no queues — just paste and analyze.
Sentence-Level Analysis
See exactly which sentences flag as AI-generated. Our highlighter shows you the specific passages that triggered detection.
Privacy-First
Your text is never stored, logged, or used for training. Analysis happens in real-time and data is immediately discarded.
Confidence Scoring
Every result includes a confidence percentage so you know exactly how certain the detection is — not just a binary yes/no.
Multi-Language Support
Detect AI text in English, Spanish, French, German, and 12+ other languages with native-level accuracy.
Model Fingerprinting
Our engine guesses which AI model likely generated the text — GPT-4, Claude, Gemini, or Llama — based on unique stylistic signatures.
Perplexity Score
Measures how predictable your word choices are. AI text typically has low perplexity — we show you the exact number.
Burstiness Score
Measures variation in sentence length. Human writing is bursty; AI writing is uniform. We quantify the difference.
