AI Detector by SEOToolPort

AI Detector by SEOToolPort is a specialized NLP utility designed for the 2026 digital ecosystem, where the distinction between human and synthetic text is increasingly blurred. The tool leverages a multi-layer detection architecture that evaluates 'Perplexity' and 'Burstiness'—the two core metrics of human linguistic variance. While many competitors rely on simple keyword matching, SEOToolPort utilizes a fine-tuned RoBERTa-based model capable of identifying structural patterns characteristic of Large Language Models (LLMs) including GPT-4o, Claude 3.5 Sonnet, and Gemini Pro. As of 2026, it serves as a critical first-line defense for SEO professionals and editors who must navigate search engine policies regarding AI-generated spam. The platform operates on a zero-trust content model, analyzing the probability of word sequences to provide a confidence score. Its lightweight, web-based deployment makes it an essential tool for rapid verification without the overhead of enterprise-level suites, focusing on accessibility and speed to support the high-velocity content cycles of modern digital marketing.
