You have a draft written with AI, and Isgen.ai flags it. Here is how to rewrite it so it reads like you, then check it.
Isgen.ai describes itself as a multilingual-first AI company whose detector checks text for AI writing in over 80 languages. Isgen.ai says any mix of AI and human text can be detected, and that it defaults to human-written when results are unclear. It also warns that student writing structured on an AI model's suggestions can still be flagged.
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.
Isgen.ai does not say on its own pages whether it detects paraphrased or humanized text.
