I was just reading this post and this question popped in my head.

I have used Grammarly for a few months now and I use it to fix grammatical errors in a post or just assist me in writing better questions(like this one). Around 5-10% was purely my edits, 80-85% was assisted by Grammarly(i.e Corrections done by Grammarly plus some edits of mine like formatting improvements, etc.) and a small percentage were done purely from Grammarly.

Even though everything I said above was focused on Grammarly, the question is, are these tools allowed on the platform?
