AI Detector by SEOToolSpot

AI Detector by SEOToolSpot is a specialized utility designed for the 2026 digital landscape, where distinguishing between human-generated and LLM-produced content (specifically GPT-5, Claude 4, and Gemini 2.0 architectures) is critical for SEO and academic integrity. The tool operates on a dual-metric linguistic model focusing on Perplexity—a measure of text complexity—and Burstiness—the variation in sentence structure and length. By analyzing the statistical probability of word sequences, the detector provides a probability score indicating the likelihood of AI intervention. Positioned as an accessible, browser-based solution, it bypasses the need for high-cost enterprise subscriptions for casual creators and small-scale SEO agencies. As search engines evolve to prioritize 'Experience, Expertise, Authoritativeness, and Trustworthiness' (E-E-A-T), this tool serves as a first-line diagnostic to ensure content maintains a human-centric profile. The architecture is optimized for low-latency processing, allowing users to verify long-form articles in seconds. While it lacks the deep API integration of enterprise competitors like Originality.ai, its zero-friction approach makes it a staple for quick content audits and freelance quality control workflows.
