How it works

The tool also includes a plagiarism checker and a readability score, so a single scan covers the main originality questions. It is designed to be accurate and transparent, showing its reasoning rather than just a yes-or-no verdict.

Winston AI is a specialist detector rather than a writing tool, and it is priced for educators and professionals rather than casual users. Like every detector, it can produce false positives, so its results should start a conversation, not end one.
