Accept/Reject Preference Learning

Detect AI-generated writing. Check if text was written by AI or humans.
















AI Writing Detector is a powerful tool that helps writers and educators produce better work in less time. TypeOS brings this capability directly into Google Docs, where you already create your documents. No more switching between applications or losing your workflow - everything you need is right where you write.
Our ai writing detector feature uses advanced artificial intelligence to understand your content and provide intelligent suggestions. Whether you're grading student essays, writing research papers, or creating professional documents, TypeOS adapts to your needs and helps you achieve better results.
Thousands of writers and educators already trust TypeOS for their ai writing detector needs. Join educators from top schools, researchers from leading universities, and professionals from Fortune 500 companies who use TypeOS every day to improve their productivity and the quality of their work.
AI detection has become a critical concern in education and publishing. TypeOS helps you identify AI-generated content and, more importantly, helps writers transform their AI-assisted drafts into authentic, human-sounding prose that maintains their unique voice.
Our humanization technology doesn't just paraphrase text - it restructures sentences, varies vocabulary, and adjusts tone to create content that reads naturally. The result is writing that passes AI detection tools like GPTZero, Turnitin, and Originality.ai while still conveying your intended message.
TypeOS believes in transparent AI use. We help writers use AI as a tool for ideation and drafting while ensuring the final product reflects genuine human thought and effort. This approach supports academic integrity while embracing the productivity benefits of AI assistance.
