Is Grammarly Worth It? — Editorial Review
Grammarly is the most widely installed AI writing assistant in the world, operating as a browser extension, desktop app, and mobile keyboard. Unlike general-purpose LLMs, Grammarly is specifically tuned for inline editing — it integrates into Gmail, Google Docs, Notion, Slack, and virtually every other writing surface. The free plan handles grammar and basic spelling, but the Premium plan at $12/mo adds tone detection, clarity scoring, vocabulary suggestions, engagement analysis, and a plagiarism checker against 16 billion web pages. For professionals whose written communication represents their work quality, it is a highly cost-effective tool.
