AI humanizer FAQ: detectors, meaning and privacy

No. We have no access to those detectors, so we cannot show you their verdicts and will not pretend to. What the gauge shows is our own AI-pattern score, measured here on four things: how much your sentence lengths vary, how many template phrases the text contains, how varied the vocabulary is, and how much of it is passive. You get that number for your original and for the rewrite, with the reasons behind both. GPTZero and ZeroGPT are free to run, so you can check the output there yourself.

Yes. Undetected.ai rewrites the robotic patterns, not your point. Your facts, your argument and your structure stay intact, so the output reads natural and is still genuinely your writing, never off-topic or broken.

No. The humanizer writes with natural rhythm and burstiness, the way a person actually writes, instead of swapping in thesaurus words that read worse than the original. The result is prose you would be comfortable publishing.

No. Undetected.ai is for clearing false AI flags and making AI-assisted drafts read naturally and professionally. It is built for marketers, SEO teams, content writers and students whose genuine work keeps getting wrongly flagged, or who want their AI-assisted drafts to read human. It is not a tool for passing off others' work as your own.

Google rewards content that is genuinely helpful and reads naturally for people. Undetected.ai makes your writing read human and removes the AI-pattern tells that can trigger flags, which is aligned with quality guidelines rather than against them.

Blog posts, marketing emails, essays, product descriptions and social copy, both long and short. You can paste a single paragraph or a section of a document, up to 1,500 words in one run on a confirmed account, and the rewrite adapts to the content type. That per-run ceiling is the same on every plan, paid or free; longer pieces are run a section at a time.

Here is the honest version. We save the text you paste and the rewrite we produce, so your history is waiting on your account page when you come back. Every run has a delete button, and we delete runs automatically after 90 days. We train nothing on it and sell it to nobody. The rewrite itself is produced by Google's Gemini API, so your text is sent to Google; our privacy page explains exactly what Google may do with it on the tier we are on today.

Yes. Choose Standard, Academic, Casual or SEO, and set how light or strong the rewrite should be, so the output matches the piece you are working on.

Plans are sized by two monthly numbers, words and runs. Starter covers 15,000 words across 60 runs a month, Pro covers 80,000 across 200 and Scale covers 250,000 across 400. Both are enforced, because a rewrite costs us a fixed amount per model call as well as an amount per word — the same page pasted in ten pieces costs us far more than the same page pasted once. No plan is unlimited: every tier carries numbers we can actually honour. See the pricing page for the full breakdown.

Yes. You can move up or down a plan whenever your volume changes, and you can cancel at any time. Yearly billing saves 25 percent on Starter, 21 percent on Pro and 19 percent on Scale compared with paying monthly.
