Grammarly
AI writing assistant for grammar, clarity, and tone — now part of the Superhuman productivity suite with AI text generation

Very Good
MFWAI score / 100
Our verdict
Grammarly remains the most widely deployed AI writing assistant in 2026, now enhanced with the Superhuman suite acquisition. For professionals who write daily across multiple platforms, the browser extension alone justifies the $12/mo Pro price. The free tier handles basic grammar — upgrade when you need tone detection and AI rewriting.
Pros
- Works everywhere — browser extension, desktop app, Gmail, Google Docs, Slack, and more
- Tone detection and rewrite suggestions go beyond grammar to improve communication impact
- Now includes Superhuman Go AI assistant and Coda workspace access with paid plans
- AI text generation with 2,000 prompts available on Pro plan ($12/mo)
Cons
- Parent company rebranded to Superhuman — bundled pricing may not suit everyone's needs
- Premium suggestions sometimes flag correct writing as needing changes
- AI content generation is basic compared to dedicated tools like Jasper or Claude
