UtilHatch AI Content Detector

Reviewers who suspect a draft was machine-written can paste it here and get a read on the language patterns inside it. The page sets out a three-step flow: add an article, essay, email or other writing sample; let the browser measure variation, repetition, vocabulary and structure; then read the signals that come back.

The analysis runs in the browser, and the site says the tool is free and needs no signup. Results are presented as a set of signals found in the text — the interface can report a mixed-signals state — rather than as a single verdict on authorship.

The site is explicit about the limits of that estimate. It tells readers to weigh the result against the drafts, sources and context they already have and not to treat it as proof, and it devotes a section to whether AI detectors can be wrong. Further pages cover how the browser-only detector works and its testing methodology and browser support.
