The AI Content Detector evaluates written text to identify statistical markers characteristic of Large Language Models (LLMs) such as OpenAI ChatGPT (GPT-3.5, GPT-4, GPT-4o), Anthropic Claude 3.5, and Google Gemini.

Key Detection Metrics: • Sentence Burstiness: Human writing exhibits high variance in sentence length and rhythm, alternating between concise punchy thoughts and complex compound structures. AI text displays unnaturally uniform cadence. • Perplexity Variance: AI models choose mathematically predictable, high-probability tokens. We map low-probability outliers that indicate authentic human nuance. • Vocabulary Diversity (TTR): Type-Token Ratio measurement detects repetitive vocabulary and generic transition words frequently overused by LLMs. • 100% Client-Side Privacy: Your documents, academic essays, and sensitive drafts are analyzed locally inside your browser and are never uploaded or stored on any server.
