Grammarly has been part of my workflow for years but the AI upgrade changed everything. GrammarlyGO drafts emails that actually sound like me — and the tone detector catches things I completely miss in my own writing.
As a non-native English speaker, Grammarly AI has made my professional communications significantly more polished. The browser extension works flawlessly across every tool I use — Gmail, Notion, Slack. Essential subscription.
The clarity suggestions are excellent for making technical writing accessible. I do wish the plagiarism checker was included at a lower tier, but the overall quality and breadth of the tool justifies the Pro price.
