When to stay with Grammarly
Documented strengths from our Grammarly review — switching isn't always the right call:
- Genuinely useful free tier — grammar, tone, and 100 AI prompts — that works almost everywhere via extensions
- Broadest platform coverage of any writing tool: browsers, desktop, mobile, Office, and Google Docs
- Newer AI agents (Humanizer, AI Detector, Citation Finder) extend it well beyond grammar checking
