tried using it before, overall it's a bit better in terms of grammar, but it made the quote feel unnatural, I prefer a proofreader because they can point out the error and fix it reasonably, and of course, a proofreader reduces my workload since I don't need to do it myself like online rephraser.
anyway, if I still can't find someone to do it for me, I may need to use a rephraser but the time for each chapter to be released will be extended, I want to avoid extending the release delay if possible.
