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 Sapling flags it. Here is how to rewrite it so it reads like you, then check it.
Sapling describes its AI detector as a free tool that gives the probability a text was generated by a model such as ChatGPT or Gemini. Sapling says its latest update targeted humanized AI text, and it warns that some tools have falsely claimed text “passed” its detector. It also says no detector, including its own, should be used as a standalone check.
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.
Sapling says its September 2026 update brought “significantly higher detection of humanized AI text.”

Sapling's AI detector, run by Sapling Intelligence, Inc., gives the probability that a text was AI-generated. Sapling also sells a Sentence Rewriter and a Rephrase feature, which it does not describe as humanizers.
Sapling says its September 2026 update brought significantly higher detection of humanized AI text. It also warns that some tools have claimed text passed its detector when no check was performed. We have not tested Sapling ourselves.
Sapling gives no single accuracy figure, saying accuracy varies with the dataset, text length and threshold, and that false positives and false negatives will occur. It says short, general and essay-like texts are more likely to be misflagged, and that it becomes much more accurate after about 50 words.
The free check covers the first 2,000 characters of a text. Pro costs $25 a month, or $12 a month billed annually, and checks up to 100,000 characters at a time.
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.
