Humanize AI Text. Leave Zero Tells.

You can paste text and see ZeroTell's quick analysis of AI-typical phrasing for free. Getting the humanized text needs an account and a Pro plan: weekly (with an intro price for your first week), monthly or yearly. Current prices for your country are on the Pricing page.

It is designed to. ZeroTell changes phrasing, rhythm and sentence structure while keeping your facts, argument and key terms in place. Light strength makes the smallest edits, while Strong restructures more freely, so pick the level that fits your text. As with any AI tool, read the result before you use it and correct anything that shifted.

Any of them. The humanizer works on the text itself, so it does not matter whether your draft came from ChatGPT, Claude, Gemini, Copilot, Llama or another AI writer, or was written by you and simply sounds too stiff. Paste plain text, choose a tone and rewrite strength, and ZeroTell handles the rest.

There are four tones: Academic, Formal & professional, Neutral & clear, and Natural & conversational. Each can be combined with one of three rewrite strengths. Light keeps your sentence order and most of your wording, Balanced reworks phrasing and flow, and Strong restructures sentences more freely. Academic with Balanced is a good starting point for essays and reports.

Treat it as a strong signal, not proof. ZeroTell scores your text sentence by sentence and highlights the parts that read as machine-written, but no detector is 100% accurate: heavily edited AI text can slip through, and some human writing gets flagged. Weigh the score together with your own judgment and the context of the writing.

You do. The text you paste into ZeroTell and the results you get back are yours to use for coursework, personal projects, publishing or commercial work, and ZeroTell claims no ownership of your writing. Just follow any rules on AI assistance that your school or publisher sets; our Academic Integrity page explains responsible use. Our Privacy Policy explains how your data is handled.
