Grammarly, is first and foremost, a misnomer. If you would genuinely like grammatical help while writing, the best thing you can do is adjust the setting in the built-in grammar checker in Docs or Word to be more strict. Grammerly is not going to make your grammar better, and stringent adherence to a constant assured and direct tone strips the human variance from writing.

Grammarly strips your voice away from you. This is especially a problem in an era of AI detectors, where the featureless grey mush that is created through Grammarly has no more of a soul than AI, leading to your paper being at risk of being flagged, and likely you having to, at the very least re-do your entire paper.

Truly, there is no rating too low for me to give Grammarly. If I could give 0 stars I would. If I could give -5 stars I would.
