Verifying Content Authenticity with Precision
Production-ready platform designed to identify AI-generated content across education, publishing, hiring, and research domains using sophisticated ensemble detection.
Advanced technology meets practical application
Calibrated thresholds for Academic, Technical, Creative, and Casual content types with specialized detection algorithms for each domain.
Combines Perplexity, Entropy, Statistical, Linguistic, Semantic Analysis, and Multi-Perturbation Stability for comprehensive detection with orthogonal signal capture.
Sentence-level highlighting with confidence scores and detailed reasoning for every detection decision.
Analyze short texts in 1.2 seconds, medium documents in 3.5 seconds with parallel metric computation.
Identifies which AI model likely generated the text - GPT-4, Claude, Gemini, LLaMA, and more.
Upload and analyze TXT, PDF, DOCX, DOC, and Markdown files with automatic text extraction.
Understanding the science behind the detection
Measures how predictable the text is using GPT-2 language model. AI-generated text typically has lower perplexity (more predictable) than human writing, which tends to be more varied and surprising.
Calculates token-level diversity and unpredictability in text sequences. Human writing shows higher entropy with more varied word choices, while AI tends toward more uniform token distributions.
Analyzes sentence length variance, punctuation patterns, and lexical burstiness. Human writing exhibits more variation in sentence structure and rhythm compared to AI's consistent patterns.
Evaluates POS tag diversity, syntactic complexity, and grammatical patterns. Examines the richness of language structures and whether they match natural human linguistic variation.
Assesses semantic coherence, repetition patterns, and contextual consistency. Detects the subtle semantic fingerprints that distinguish AI-generated content from human writing.
Tests text stability under random perturbations. AI-generated text tends to maintain higher likelihood scores even when slightly modified, while human text shows more variation.
