Kazan SEO AI Detector
Professional-grade AI content detection and semantic SEO analysis at zero cost.
High-fidelity linguistic analysis for detecting GPT-4o, Claude 3.5, and Gemini-generated content in the APAC region.
AI Detector by SpellCheck.com.au has evolved into a sophisticated linguistic auditing tool by 2026, specifically optimized for the nuances of Australian English and global academic standards. The tool operates on a proprietary ensemble model that evaluates text through two primary vectors: Perplexity (the randomness of word choice) and Burstiness (the variation in sentence structure). Unlike first-generation detectors, this platform utilizes a transformer-based architecture that identifies the specific 'fingerprints' of modern LLMs including GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro. Its technical infrastructure is designed for low-latency processing, allowing users to scan documents up to 25,000 words in seconds. Positioned as a key utility for the APAC market, it provides localized data residency and compliance with Australian privacy standards. The 2026 version features enhanced detection for 'AI-paraphrased' content, identifying patterns left by tools like Quillbot or specialized humanization layers. It serves as a critical infrastructure piece for publishers, educational institutions, and SEO agencies looking to maintain content authenticity in an AI-saturated market.
Uses a visual heatmap to show the mathematical randomness of word choices throughout the text string.
