Three rewrite strengths
Light, Balanced and Aggressive, with six styles and six purposes, so the rewrite fits the text.
Free trial: 500 words. No sign-up needed.
You have a draft written with AI, and JustDone flags it. Here is how to rewrite it so it reads like you, then check it.
JustDone describes its AI detector as a tool that scores how much of a text reads as AI-written and flags the exact sentences. JustDone says it learns from AI text that has already been run through a paraphraser or grammar tool, so light rewording is what it claims to catch. It also says accuracy improves with longer texts and that short fragments and lists are the hardest cases.
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.
JustDone claims its detector catches “humanized” AI text by looking for patterns that survive paraphrasers and grammar tools.

JustDone AI Detector is run by GM Appdev Limited of Limassol, Cyprus, and scores how much of a text reads as AI-written, flagging individual sentences. JustDone also sells an AI humanizer and paraphraser, and the detector page offers one-click humanizing of flagged text.
JustDone claims it catches paraphrased and “humanized” AI text through patterns that survive paraphrasers and grammar tools. We have not tested JustDone ourselves.
Its detector page claims 80% overall accuracy, 98% on academic and scientific texts and a 10.3% error rate, described as independently benchmarked. The methodology post it links to instead says “roughly 94% accuracy in internal testing” and names no independent benchmarker.
Premium includes an “Estimated Turnitin AI score”, which JustDone says is based on its own model. It says it is not affiliated with Turnitin and that institutional results may differ.
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.
