Kazan SEO AI Detector
Professional-grade AI content detection and semantic SEO analysis at zero cost.

Enterprise-grade linguistic forensics for multi-model synthetic content detection and verification.
AI Detector by TextExpert represents a sophisticated evolution in forensic linguistics, specifically engineered for the 2026 digital landscape where generative AI saturation is near-total. The tool utilizes a hybrid detection architecture that combines deep learning transformers with statistical analysis of perplexity and burstiness. Unlike legacy detectors that provide a simple binary output, TextExpert provides a granular probability heatmap, identifying specific segments of text that exhibit synthetic structural markers. Its 2026 market position is solidified through its 'Multi-Model Attribution' engine, which can distinguish between outputs from GPT-4o, Claude 3.5, Gemini 2.0, and various Llama-based local models with high precision. The platform is architected for scale, featuring a robust API that handles high-concurrency requests for enterprise content moderation and academic platforms. Beyond simple detection, TextExpert incorporates an 'Anti-Humanizer' layer, designed to see through common evasion techniques like word-spinning or synonym substitution. By maintaining a massive, evolving dataset of synthetic linguistic fingerprints, TextExpert provides publishers, educators, and legal professionals with a verifiable audit trail for content authenticity, ensuring that the human element of communication remains distinguishable in an increasingly automated world.
