AI Detector by SEOToolExpert

The AI Detector by SEOToolExpert is a specialized NLP utility designed for the 2026 digital landscape, where the distinction between human and synthetic text has become increasingly blurred. Utilizing advanced probability mapping, the tool evaluates text sequences based on two primary metrics: Perplexity (the randomness of word choice) and Burstiness (the variation in sentence structure). As of 2026, the engine has been updated to detect structural fingerprints from GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro. Unlike basic detectors, it provides a localized heatmap that identifies specific segments within a document that exhibit high synthetic probability. This tool is primarily utilized by SEO agencies and academic institutions to verify the authenticity of high-volume content submissions. The architecture operates as a thin-client interface that leverages back-end transformer models to cross-reference linguistic patterns against known LLM training weights. While no detector can claim 100% certainty, SEOToolExpert focuses on reducing false positives through contextual awareness, making it a reliable first-pass filter for content moderation and quality assurance workflows in an AI-saturated market.
