Three rewrite strengths
Light, Balanced and Aggressive, with six styles and six purposes, so the rewrite fits the text.

You have a draft written with AI, and SurgeGraph flags it. Here is how to rewrite it so it reads like you, then check it.
SurgeGraph describes its free AI Detector as a quick check of whether writing was generated by AI or written by a human. SurgeGraph says it stays reliable on paraphrased or lightly edited text because it analyzes how sentences tie into overarching themes. It also says it adds a check of whether your content passes all major AI detectors.
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.
SurgeGraph says its detector can catch paraphrased AI text from tools like QuillBot and Grammarly and stays reliable when content has been paraphrased or lightly edited.
