Cons

Grammarly can occasionally be overly prescriptive with style suggestions, flagging intentional stylistic choices like sentence fragments, colloquialisms, or creative phrasing as errors.

Complex or highly nuanced queries can occasionally be misinterpreted, leading to answers that miss the specific angle or context the user intended.
The free tier imposes daily limits on Copilot and Pro model queries, which can be restrictive for heavy researchers who rely on advanced features throughout the day.
