Pros & cons
Pros
- Best-in-class English grammar and spell checker after 15+ years of training data
- Coverage everywhere: browser extension, desktop apps (Mac/Windows), mobile keyboards, Word and Google Docs add-ins
- Tone detector flags how a message will read before you send it
- Plagiarism checker and AI-generated text detector are bundled in Pro at $12/mo annual
Cons
- Subscription-only premium - no perpetual license, monthly price jumps to around $30/mo without annual commitment
- Acts as an editor, not a full content writer - long-form generation is weaker than Jasper, Writesonic or Sudowrite
- Suggestions can be over-aggressive on style and voice, especially on creative or technical writing
- Generative AI prompts are capped (100/mo Free, 2,000/mo Pro) - heavy users hit the ceiling fast
