What is Grammar & Spell Checker?

Grammar checker online to get instant grammar, spelling, and style corrections powered by the LanguageTool API - completely free and without requiring an account.

Unlike Grammarly which requires installing a browser extension, creating an account, and giving it access to everything you type, this tool works directly in your browser with a simple paste-and-check workflow. Errors are highlighted inline with colored underlines: red for spelling, blue for grammar, yellow for style. Click any error to see suggestions and apply fixes with one click. View readability scores and an overall quality score to gauge your writing. Supports English (US and UK), German, French, Spanish, Portuguese, Dutch, Italian, Russian, Polish, and more. No signup, no extension, no subscription required.
