I loved Grammarly. But it has changed post LLM boom. The underlying concept was awesome as they take grammatical rules from a book of english grammar rules into a linter. Then it let you select the tone and adjusted some for marketing/engagement so it sounds good on Twitter. I have severe dyslexia and struggled with tone.
Lately, like following ChatGPT 3.5 release era, I had found Grammarly now replacing entire sentences with LLM replacement which are random and inject bias to being near useless. It did this some before. The problem is I can't even tell if it's defensible from a grammatical point when it uses an LLM to do this. At some point Grammarly reached too far in the cookie jar and I no longer trusted that someone who read the Grammar rule book verified any part of the elaborate suggestions.
I haven't logged in for months. I guess I was no longer learning from it. I need to take a closer look but sys admin outrage from pushy sales people doesn't bode well in my mind.
