Writing Free Tier

Grammarly

Grammarly is an AI writing assistant that checks your grammar, spelling, tone, and clarity across nearly any app or website where you type.

Last updated 2026-05-04
Our Take
Grammarly is the default AI writing assistant for anyone who types for a living, with unmatched coverage across browsers, desktop apps, and mobile keyboards. The Free tier is genuinely useful for catching errors, but Pro at $12/mo unlocks the rewrites and tone tools that justify it. Now part of the Superhuman Suite, it's leaning harder into team brand voice and agentic AI to compete with ChatGPT-style assistants.
Best For
Professionals, students, and teams who write frequently across email, documents, and chat and want consistent, on-brand, error-free communication. Especially useful for non-native English writers and customer-facing teams.
