Grammarly is the most widely used writing assistant in the world, with 30 million daily users. But is the Premium plan worth $12/month when the free version catches most errors? We tested both for 30 days.

Pros and Cons
Pros
- Works everywhere — browser, Word, Google Docs, desktop app
- Tone suggestions help match the right register for each audience
- Plagiarism checker covers 16 billion web pages
- Full-sentence rewrites save significant editing time
- Performance: catches errors that slip past manual proofreading
Cons
- Premium is expensive at $144/year
- Suggestions can be overly conservative (softens direct writing)
- Struggles with highly technical or specialised content
- The AI rewrites can sometimes change meaning subtly
- Free plan has become more restrictive over time
Is Premium Worth It?
Yes, if you write professionally. For bloggers, content marketers, copywriters, and anyone whose writing directly generates income, the time saved justifies the cost. The clarity suggestions and full-sentence rewrites alone save us 30+ minutes per long-form article.
No, if you write casually. The free plan handles grammar and spelling competently. Most casual writers won't get $12/month of value from the premium features.
Alternatives to Consider
- ProWritingAid ($70/year) — more in-depth analysis, better for fiction writers
- Hemingway Editor ($20 one-time) — focuses on readability, great for clear writing
- Claude / ChatGPT — better for full rewrites and ideation, less good at inline editing
The Verdict
Grammarly Premium earns its price if writing is a significant part of your professional output. For everyone else, the free version is one of the best free tools available.
