Yes, Turnitin is our primary benchmark. Every update we ship is tested against the latest Turnitin AI detection model. Our users routinely report 0% AI detection scores on Turnitin submissions.

Absolutely. Lawyers, consultants, and business professionals use TypeOS daily to draft client memos, reports, and proposals. The humanizer preserves technical terminology and professional tone while eliminating AI fingerprints.

Most humanizers just swap words with synonyms, which sounds awkward and still gets flagged. TypeOS uses advanced language models to completely rephrase your text at the structural level — the way a human editor would.

Yes. Our legal users draft initial versions of briefs, memos, contracts, and client letters with TypeOS. The AI writer understands legal terminology and citation formats.

Everything. Essays, research papers, dissertations, blog posts, legal briefs, consulting reports, cover letters, emails, creative writing — if it's text, TypeOS can write it and humanize it.

Yes. TypeOS analyzes your input to match tone, formality, and vocabulary level. A casual blog post stays casual. An academic paper stays academic. A legal brief stays formal.

TypeOS achieves 98.5% detection accuracy across 50,000+ tested documents, with a false positive rate of just 1.2% on human-written text — approximately 7× lower than the industry average of 8.5% (Source: TypeBench 2025). Our multi-model detection engine combines perplexity analysis, writing pattern recognition, and vocabulary fingerprinting to achieve this accuracy.

Yes. TypeOS detects content generated by all major AI writing tools including ChatGPT (GPT-3.5 and GPT-4), Claude, Gemini, LLaMA, Mistral, and others. Our detection engine is regularly updated as new models are released and re-evaluated against the TypeBench benchmark.

Yes, TypeOS offers free AI detection scans. You can check text for AI content directly in Google Docs without any cost. Premium plans offer higher usage limits and batch scanning.

In independent benchmarking (TypeBench 2025), TypeOS outperforms GPTZero (86% accuracy, 9% false positive rate) and Turnitin AI detection (84% accuracy, 11% false positive rate) with 98.5% accuracy and a 1.2% false positive rate. Beyond accuracy, TypeOS works directly inside Google Docs — no copy-pasting — and includes plagiarism checking, AI humanization, and citation verification in one tool.

TypeBench is TypeOS's internal AI writing evaluation benchmark, published in November 2025. It measures detection accuracy and false positive rates across 50,000+ documents spanning academic essays, blog posts, reports, and creative writing — generated by a range of AI models including GPT-4, Claude 3, and Gemini 1.5. The full methodology is available at typeos.com/research/typebench.

Absolutely. TypeOS is designed for educators. You can scan student submissions directly in Google Docs or through Canvas integration, get sentence-level AI highlighting, and generate originality reports. TypeOS's low 1.2% false positive rate means fewer wrongful flags against genuinely human-written student work.
