The writing quality improvement is incredible. My content reads naturally and professionally every time.
A basic detector gives you a single score — human or AI. Advanced AI Scan breaks down detection at the sentence level, showing probability scores for each segment of text, analyzing writing patterns, perplexity, and burstiness. This gives educators, institutions, and compliance teams the granular evidence they need.
Perplexity measures how predictable or "flat" text is — AI-generated content tends to score lower (more predictable). Burstiness measures variation in sentence complexity and length. Human writing tends to have high burstiness. Advanced AI Scan shows both metrics to give a multi-dimensional view of how the text was likely written.
Yes. Unlike simple pattern matching, Advanced AI Scan uses multi-model analysis to detect AI writing even after light editing, paraphrasing, or synonym replacement. It looks at structural patterns that survive surface-level rewrites.
Yes. TypeOS supports bulk scanning for institutions, publishers, and platforms that need to screen large volumes of documents. Upload multiple files at once and receive detailed per-document reports.
Yes. TypeOS offers an API for Advanced AI Scan, allowing you to integrate deep detection into your own platform, LMS, or workflow. Visit our research page for API documentation and access.
Advanced AI Scan results can be exported as PDF reports containing sentence-level scores, overall probability, and supporting analysis. These reports are designed for academic review boards and institutional compliance.
