Most detectors are a black box. We show ours.
Detectors do not just say yes or no. They flag measurable patterns. We surface the same four, so you can see exactly why a draft reads machine-made, whether it is yours or someone else's.
Burstiness
Humans vary sentence length without thinking. Models flatten it. Detectors weight this signal hardest.
Rhythm
Runs of same-length sentences read machine-made. We flag every one and show you where.
Vocabulary
Delve, seamless, robust, a testament to. The stock words that scream generative AI.
Punctuation
Em-dash pileups and stacked rule-of-three lists are among the loudest tells.
Questions
Is the detection score the same as GPTZero?+
The free score is a heuristic proxy built on the same measurable signals real detectors use, so it moves in the same direction. Sign up free and we can verify it against Winston AI, a third-party detector, for an independent score.
Does the humanizer change what my text says?+
No. It targets the machine fingerprint (rhythm, stock phrasing, punctuation) while keeping your meaning and structure. You can compare before and after side by side, from the Humanizer section once you are signed in.
What should I use this for?+
Checking any draft you are not sure about, and cleaning up your own AI-assisted writing before it goes out: marketing copy, LinkedIn posts, newsletters, reports. Built for professional writing, not homework.
What happens if I go over my word limit?+
You will see the option to upgrade before any request fails. Free, Lite, Pro, and Studio each raise your monthly quota, which covers both Winston-verified checks and humanize rewrites.
Do I need to install anything?+
No. Paste or upload text in the browser. The free score runs instantly with no account; Winston-verified checks and humanizing just need a free sign in.
Try it on the draft you are least sure about.
Paste it, see the score, and if it needs work, clean it up until it reads human. No card required to start.
