Grammarly costs $144/year. The free version catches basic errors but locks the good stuff behind the paywall. Here's what you can get for free and when paying actually makes sense.
What Free Grammar Checkers Catch
The BriskTool Grammar Checker uses AI to find:
- Spelling errors
- Subject-verb agreement issues
- Missing or extra punctuation
- Run-on sentences
- Common word confusion (their/there/they're)
- Verb tense consistency
For emails, blog posts, social media, and everyday writing, that covers 95% of what you need.
What Grammarly Premium Adds
Tone detection, vocabulary suggestions, wordiness fixes, formality level, plagiarism checking, and genre-specific writing conventions. Useful for academic papers, professional reports, and published content.
Who Should Pay for Grammarly
Students writing papers every week. The plagiarism checker alone is worth it.
Professional writers who publish content regularly and need consistent quality.
Non-native English speakers who want tone and formality guidance.
Who Should Use Free
Everyone else. If you're checking an email, a Slack message, a social media post, or a one-off document, a free grammar checker handles it fine. You don't need a $12/month subscription to fix a typo.
