You have a draft written with AI, and StealthWriter flags it. Here is how to rewrite it so it reads like you, then check it.
StealthWriter describes its AI detector as a check of how likely text is to be flagged as AI-generated, with sentence-level feedback. StealthWriter publishes no accuracy figure and says AI-generated writing can go undetected. Its Deep Scan marks individual sentences rather than giving only one score for the whole text.
RewriteMax rewrites how the whole text is written, its rhythm, structure and phrasing, instead of swapping single words, and leaves the decisions about meaning with you.
StealthWriter does not say on its own pages whether it detects paraphrased or humanized text.
What StealthWriter says about itself on its own pages. We have not measured StealthWriter yet; our measured results are on the ZeroGPT page.
| Question | What StealthWriter says |
|---|---|
| Free use | No account needed for up to 500 words per scan; the Free plan lists 10 AI scans a day and 1,000 words per input |
| Paid plans | Starter to Scale at $20–$400 a month, with 50–2,000 AI scans a day and 5,000 words per input |
| Accuracy it claims | No accuracy figure; says a score is “an estimate, not proof of authorship” |
| How it works | V1 and V2 detector models, plus a Deep Scan with sentence-by-sentence color-coded highlights |
| Humanized text | Presented as a check before and after using StealthWriter’s own humanizer |
| Minimum length | At least 100 words recommended; shorter passages may be less accurate |
Light, Balanced and Aggressive, with six styles and six purposes, so the rewrite fits the text.
Check the rewrite on the same page; the detector uses ZeroGPT’s detection API.
Lock up to 20 names, terms or phrases, and keep quotes exactly as written.
We publish the method and results of our tests instead of a success-rate table.
A flag from StealthWriter can cost you time and credibility, even when the writing is yours.
Detectors misread human writing too; a 2023 study found seven detectors flagged non-native English essays as AI 61% of the time on average.
Turn a generic AI draft into writing that sounds like you and says what you mean.
Rewrite a whole draft in one pass instead of editing it sentence by sentence.

Detectors change often; a full rewrite does not rely on one detector’s current blind spots.
Use it where AI-assisted writing is allowed, and disclose AI help when required.
Rewrite AI-assisted drafts where your course allows it, and keep your drafts as a record.
Turn AI drafts into articles that read naturally and add real expertise.
Deliver copy you have reviewed line by line before a client checks it.
Keep a consistent, personal voice across AI-assisted posts.
Rewrite AI copy into your brand’s style and tone.
Keep terminology, hedges and citations exact while the phrasing becomes yours.
Make AI-assisted emails and reports direct and personal.
Make captions and posts sound like a person, not a template.
StealthWriter AI Detector is a checker from StealthWriter, a service of AiVantage LLC. StealthWriter’s main product is a humanizer; it calls itself “a tool to humanize AI text, with a built-in detector.”
StealthWriter makes no claim that its detector catches humanized text. It presents the detector as a way to scan writing before and after using its own humanizer. We have not tested StealthWriter ourselves.
StealthWriter publishes no accuracy figure. It says human writing can be flagged as AI, AI writing can go undetected, and a score should not be the sole basis for academic or employment decisions.
The detector page needs no account and allows up to 500 words per scan, with daily demo limits it does not quantify. The Free plan lists 10 AI scans a day and 1,000 words per input.
It should read more naturally, not less. Any automated rewrite can change wording or details, so compare it with your draft before you use it.
Essays, articles, blog posts, emails, reports and social posts each have a purpose setting, with six styles from academic to persuasive.
Yes. You can humanize up to 500 words free without an account, and the AI Detector is part of the same trial.
