The company is called Grammarly, calling the employees "Grammarlians" would be the correct grammar. If the company was Grammar, then the right term would be "Grammarians".
I see what you did there...
The human “grammarlians” will now be replaced by “grammarLLMs.”
I've yet to encounter a cutesy name for an organization's employees that isn't cringey, but ooof, when it's used in layoffs it feels so tone deaf. I really wish the name fad would pass.
In Japanese, grammar is bumpou. I really wish they used that and called them bumpkins.
