How our algorithm
decodes authenticity.
Detecting AI content requires more than just keyword matching. Our system uses advanced NLP (Natural Language Processing) to identify the subtle "digital fingerprints" left by generative models.
Deep Linguistic Analysis
Our algorithms analyze sentence structure, vocabulary diversity, and semantic patterns that are uniquely characteristic of large language models.
Perplexity & Burstiness
We measure how 'random' or 'predictable' text is. AI tends to be highly predictable (low perplexity) with consistent sentence lengths (low burstiness).
Multi-Model Cross-Checking
Your text is processed through specialized classifiers trained on millions of human and AI-generated samples from GPT-4o, Claude 3.5, and Gemini 1.5 Pro.
