About Grammarly
Grammarly is a Content & Writing tool shaped around the needs of everyone who writes professionally. On the strengths side, free version catches 90% of common mistakes; on the depth side, browser extension works in every text field on the web. Day-to-day you'll live in Grammar + spelling and Clarity + conciseness, with the rest of the suite plugging into those two. There's a genuinely free plan to start, with paid upgrades for teams that outgrow it. Grammarly's free plan is enough for most writers.

Bottom line
Should you use Grammarly?
Install the free version everywhere; upgrade to Premium if you ship long-form content weekly. For teams, Grammarly Business is worth it for shared style guides alone.
