StealthWriter is a web app that rewrites AI-generated text (from ChatGPT, Claude, Gemini and others) so it reads more naturally, with a built-in AI detector. The free plan gives 10 humanizations and 10 AI scans a day; paid plans start at $20 a month. Its own disclaimer says it does not promise how third-party AI detectors will classify the output.

The bottom line

A humanizer with a usable free tier and clear daily limits. It makes no promise about third-party detectors, and you are responsible for following the AI rules where you study or work.

What it really isStealthWriter.ai — AI text humanizer that rewrites AI-generated content to evade AI detectors.

Our takeStealthWriter rewrites AI drafts at a chosen rewrite level and checks them with its own AI detector in the same screen.

The free plan is usable for short texts (1,000 words per input). Paid plans raise the daily limits and add its stronger models. The vendor's disclaimer says it does not claim any particular result from third-party detectors, and it tells users to follow school and workplace rules on AI writing.

Why we rate itRare combo of humanizer + built-in detector in one UI; free tier lowers the barrier; tiered daily limits scale predictably with team size.

The catchDaily humanization caps on all plans mean heavy users hit limits fast.

Input is capped at 5,000 words per submission even on top paid tiers. Aggressive rewriting can introduce awkward phrasing that still needs manual review.

Trade-offs

Friction report

Trade-offs to know before signing up.

Time to value
Fast: paste text, pick a rewrite level and get a result in the browser; no download needed.
Scale breakpoint
Daily caps (10 to 2,000 humanizations by plan) and a 5,000-word limit per input on every paid plan.
Walled garden
Moderate: no public API or browser extension, so text is copied in and out of the web app.

Still a fit?

If none of these block you, start on the free plan.
