Anyword AI Detector
Enterprise-grade content verification and AI detection for high-performance marketing teams.
Transparent, no-cost AI content verification for academic and professional integrity.
The AI Detector by SpellCheck.org is a specialized utility designed to address the proliferation of generative AI in digital content. In the 2026 landscape, where LLM-generated text (GPT-5, Claude 4, etc.) has become ubiquitous, this tool serves as a critical diagnostic layer for editors and educators. Technically, it employs a combination of perplexity and burstiness analysis to differentiate between human and synthetic writing patterns. Perplexity measures the 'randomness' of word choice, where lower scores often indicate AI patterns, while burstiness evaluates sentence structure variance. Unlike enterprise-grade platforms that require heavy subscriptions, SpellCheck.org's tool focuses on accessibility and immediate browser-based feedback. Its market position is that of a high-utility 'entry-level' validator, providing a baseline probability score that can be used to flag content for further human review. The architecture is optimized for low-latency text processing, utilizing n-gram probability distributions to identify the statistical signatures of common large language models without requiring user account creation or API integration overhead.
Calculates the statistical unpredictability of the text based on standard language model datasets.
