Updated
In short: MerciApp is ranked #1 of 88 as of 7 October 2026, ahead of Sapling and LanguageTool. The best-ranked option with a free plan is Sapling. The lowest first paid tier on this page is GrammarCheck.ai at $0.21/mo.
Grammar checkers can help you review writing, but the kind of feedback and where you can use it vary. Compared on style suggestions and tone detection, the entries also show supported languages and availability as browser extensions, desktop apps, or mobile apps. Check free-plan availability and paid-from pricing alongside those features. Sapling, LanguageTool, and Grammarly are among the options to consider. Start with the languages you write in and the devices you use, then decide whether you want help with phrasing and tone as well as grammar while drafting or editing.
