Grammarly is the most recognized grammar checking tool in the world — but in 2026, its free plan has become a showcase for features you cannot use without paying. Red squiggles on basic errors are free. Everything else — tone detection, clarity rewrites, style suggestions, plagiarism checking — requires Grammarly Premium at $12–$30 per month.
This is a direct comparison between Grammarly free and AITextKit's free AI Grammar Checker — no paid plans, no upsells, just what you actually get for free.
