What it is

Grammarly checks spelling, grammar, clarity and tone wherever you type, and the Pro tier adds full-sentence rewrites, tone adjustment, plagiarism and AI-text detection and 2,000 AI prompts per member each month. Pro costs $12 per member per month on annual billing ($30 monthly), a free plan with 100 AI prompts is always available, and the parent company rebranded as Superhuman in late 2025. It is an editor rather than a copy generator, so it will not draft a campaign from a brief, and Trustpilot reviews frequently cite unexpected renewals and hard-to-reach support.

Standout capability

Works as an overlay in almost every app, so edits happen where you write rather than in a separate tool

Community sentiment

What people praise

Reviewers like that real-time corrections and clarity rewrites follow them into email, browsers and Office without changing their workflow.

What people complain about

Users complain about suggestions that flatten their voice, intrusive pop-ups, surprise renewal charges and chatbot-only support since the Superhuman changes.
