Kazan SEO AI Detector
Professional-grade AI content detection and semantic SEO analysis at zero cost.
Enterprise-grade linguistic pattern recognition for identifying synthetic content in seconds.
AI Detector by SEOToolPost is a sophisticated linguistic analysis engine designed to differentiate between human-written and AI-generated content. As of 2026, the tool leverages a hybrid architecture combining transformer-based classifiers (specifically optimized BERT and RoBERTa variants) and statistical analysis of perplexity and burstiness. Unlike simpler tools, it is engineered to detect nuances across the latest LLM iterations, including GPT-5, Gemini 2.0, and Claude 3.5. The platform serves as a critical infrastructure component for SEO specialists and academic auditors who require rapid, non-invasive verification of content authenticity. The technical methodology focuses on 'predictability analysis'—identifying the low-entropy word choices typical of autoregressive models. Positioned as a high-accessibility utility in the 2026 market, it prioritizes a low-friction user experience by bypassing the need for mandatory registration or complex API configurations for standard web users, while maintaining a high accuracy threshold for short-to-medium length text blocks.
Measures the randomness of text; lower perplexity scores indicate a higher likelihood of AI generation.
Professional-grade AI content detection and semantic SEO analysis at zero cost.
Forensic-level AI content detection and advanced humanization for SEO-proof content.
Transform AI-generated text into undetectable, human-grade content with advanced linguistic humanization.
A non-profit open-source detector for educational integrity and transparent AI verification.
Verified feedback from the global deployment network.
Post queries, share implementation strategies, and help other users.
Analyzes sentence structure variation. Humans tend to have 'bursty' writing with varying sentence lengths, while AI is uniform.
Utilizes cross-lingual language models to detect AI patterns in non-English languages including Spanish, French, and German.
Utilizes a lightweight frontend-to-API bridge to return results in under 500ms for standard text blocks.
Uses session-based stateless processing to allow immediate utility without data persistence or user login.
Internal model training on datasets from GPT-3.5, GPT-4, and Gemini to recognize specific model signatures.
The classifier looks at the semantic flow between paragraphs rather than just individual word choices.
Ensuring that hired writers are delivering original human content rather than bulk-generated AI text.
