Kazan SEO AI Detector
Professional-grade AI content detection and semantic SEO analysis at zero cost.
Multi-model linguistic analysis for high-precision AI content verification.
AI Detector by TextToolz is a specialized linguistic analysis platform designed to identify patterns generated by Large Language Models (LLMs) including GPT-4o, Claude 3.5, and Gemini 1.5 Pro. As of 2026, the tool occupies a strategic niche in the market by offering high-velocity, browser-based detection without the friction of mandatory account creation. The technical architecture leverages a proprietary ensemble of perplexity and burstiness metrics to determine text provenance. By evaluating the predictability of token sequences, it provides a probability score that distinguishes between human-authored nuances and the statistically probable outputs of neural networks. In an era where AI-generated content is flooding the web, TextToolz serves as a critical filter for SEO professionals, educators, and content managers who require rapid validation of original creative work. The tool's 2026 positioning focuses on 'Hybrid Detection'—the ability to identify text that has been human-edited but remains fundamentally AI-structured, providing users with a granular heatmap of suspicious segments rather than a simple binary pass/fail result.
Calculates the complexity of the text; AI models typically aim for low perplexity, making their text highly predictable.
