Why You Probably Don't Need Grammarly Premium
Grammarly Premium costs $140–360/year. Its core advantage is advanced suggestions like word choice, tone detection, and engagement metrics. But for most writers, free tools cover 90% of the same ground:
- • Grammar and spelling: Any free tool handles this well
- • Clarity: Hemingway Editor is arguably better for readability
- • Paraphrasing: QuillBot's free tier outperforms Grammarly Premium for rewrites
- • AI editing: Claude and ChatGPT free tiers give you GPT-4-level writing review at no cost
Where Grammarly Premium wins: real-time feedback in the browser as you type — without needing to paste text. If you write in many different places and want seamless suggestions, that's the use case where the premium price is justified. Otherwise, QuillBot + Hemingway covers it.
