Use boundaries
AI Detector terms and disclaimer
This page describes the boundaries of the current free detection features. Last reviewed: 2026-08-27.
Current features
AI Detector currently provides no-sign-up analysis of writing-pattern signals in Chinese, English, and mixed-language text. You can paste text or import TXT, Markdown, DOCX, and text-based PDF files in the browser. Features, availability, limits, and page descriptions may change as the product is updated.
Reasonable use
Only analyze text that you are permitted to process, and follow applicable law, contracts, school rules, workplace policies, and data-handling requirements. Do not use the tool to harass, discriminate, defraud, bypass security, or make unreviewed high-stakes decisions about another person.
Result disclaimer
A result is a review signal about writing patterns. It is not proof of authorship, a specific product source, plagiarism, academic misconduct, or another fact. False positives and false negatives are possible. For academic, employment, legal, disciplinary, or other consequential decisions, automated detection must not be the sole evidence.
Availability
Browser support, network conditions, device resources, file structure, and static-resource status can affect the experience. We do not promise that every device, region, file, or moment will complete an analysis. If the service is unavailable or evidence is limited, stop over-interpreting the result and use an appropriate human review process.
