What is Grammarly?
Grammarly is an AI-powered writing assistant that checks grammar, spelling, tone, and clarity across browser windows, desktop apps, mobile keyboards, and a standalone editor. The free tier handles core correction; Premium adds rewrites and tone adjustments; Business adds organization-wide style guides and analytics.
Most buyers come to Grammarly expecting a glorified spell-checker and discover a tool that quietly changes how they write. Premium's tone detection is particularly valuable for non-native English writers and customer-facing teams who need to keep messaging consistent across many people.
Grammarly is best evaluated on the writing you actually do — not on the marketing examples on the pricing page. Connect it to your email, Slack, and document editor for a week, then check whether the suggestions feel like signal or noise.
