@MLClark I regularly see AI-preedited manuscripts and don't know why this is still in use. For every mistake it corrects, it adds another one. It deletes information, adds information, changes cause-effect relationships, changes text from A to B in one sentence and from B to A in the next, and even changes data values. If the original text contains ambiguous phrasing, it simply changes it to one of the possible options without highlighting that other versions might be intended.
@MLClark Now, seeing that this is pitched as a cheap tool for improving your manuscript to people who do not have the language skills to check their final text, a wave of retractions will come our way. And lots of publications build on bullshit publications.
