Grammarly

Grammarly is the ubiquitous editing layer: browser, Docs, Slack, desktop, and its own editor. The free tier catches spelling and basic grammar. Paid plans add tone, clarity, plagiarism, team style guides, and generative rewrites.

Content designers use it as a final correctness pass, not as a source of truth for product strings. It will happily polish a button label that still violates your voice chart. Keep Frontitude, Ditto, or Writer for governance; keep Grammarly for the last mile.
