AI Detector by SEOToolPro

AI Detector by SEOToolPro is a high-fidelity linguistic analysis engine engineered to distinguish between human-authored and machine-generated text. In the 2026 digital landscape, where LLMs produce highly sophisticated synthetic content, this tool employs a multi-layered approach using transformer-based classifiers. It specifically evaluates 'Perplexity'—the measure of text randomness—and 'Burstiness'—the variance in sentence structure and length. The technical architecture is calibrated to detect outputs from the latest models including GPT-4o, Gemini 1.5 Pro, and Llama 3.1. Beyond simple percentage scores, it provides a token-by-token heatmap highlighting sections with high predictability scores. This makes it an essential utility for SEO professionals aiming to maintain E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) standards and for academic institutions requiring a low-false-positive environment for student assessment. The tool operates as a client-side and server-side hybrid to ensure rapid analysis speeds while maintaining high data privacy for processed strings.
