AI Detector by SEOToolsHH

AI Detector by SEOToolsHH is a specialized utility within the broader SEOToolsHH suite, designed to analyze linguistic patterns for markers of machine generation. In the 2026 landscape, where large language models (LLMs) have become ubiquitous, this tool serves as a critical checkpoint for content strategists and educators. The technical architecture leverages perplexity and burstiness metrics—two core statistical properties of text—to differentiate between the structured, predictable output of AI models like GPT-4o, Claude 3.5, and Gemini 2.0, and the more varied, irregular cadence of human prose. The platform is optimized for high-speed processing, utilizing a lightweight backend to deliver results in near real-time without the overhead of enterprise-level registration processes. As search engines increasingly prioritize 'Helpful Content' with high EEAT (Experience, Expertise, Authoritativeness, and Trustworthiness), SEOToolsHH provides a necessary diagnostic layer to ensure content portfolios do not trigger algorithmic penalties. It is particularly effective for high-volume scanning of blog posts, academic submissions, and marketing copy, offering a transparent percentage-based probability score that helps users decide if a text requires human rewriting or fact-checking.
