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

Advanced NLP-driven linguistic analysis for distinguishing human-authored text from generative AI outputs with high precision.
The AI Detector by PlagiarismSoftware represents a sophisticated implementation of Large Language Model (LLM) fingerprinting and linguistic entropy analysis. By 2026, the tool has integrated multi-vector detection mechanisms that analyze text for 'burstiness' and 'perplexity'—two key indicators of AI-generated content. The technical architecture is designed to identify outputs from various models including GPT-4o, Claude 3.5 Sonnet, Gemini Ultra, and Llama 3 iterations. It functions by comparing the probability distribution of words against known human linguistic patterns. For the 2026 market, it serves as a critical infrastructure component for digital publishers, educational institutions, and SEO agencies who need to maintain E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) compliance. The platform offers a low-latency interface that processes large documents by breaking them into semantic chunks, providing a granular heatmap of AI-likelihood across the text rather than just a binary result. This depth allows users to identify 'AI-assisted' content versus 'fully AI-generated' content, a distinction that has become vital for legal and academic standards in the mid-2020s.
Simultaneously scans text against the unique stylistic signatures of GPT, Claude, and Gemini models.
