I can imagine how hard is being a human editor, My friend published his 3000 pages novel that he finished it up in 12 years and then the editor should sort everything and cut it into 100 pages only, at the same times the demanding readers keep pushing him to published the book and he made it after several months postponed, through soem discussion of the published books, the editor than decided to re-edit the novel and make it a bit different than the first edition. Grammarly working only for English right? each different language has its own spesific editors I think.
