Grammarly is a widely used writing extension that checks grammar, spelling and style as you type across most websites. Some writers look for alternatives because they need multilingual support, want a different pricing model, or prefer a checker with fewer permissions. This page compares what to look for.
What a grammar checker extension for Chrome does
A grammar checker extension reads text as you type in text boxes across websites, then underlines spelling, grammar and style issues with suggested fixes. Most work inside email, social media and document tools directly in the browser, so you don't need to copy text into a separate app to proofread it.
LanguageTool as a multilingual alternative
LanguageTool checks grammar and style in multiple languages, which makes it a practical choice if you write in more than English. It has a free plan covering core grammar and spelling checks, with paid plans adding more advanced style suggestions. It works as a Chrome extension in the same way Grammarly does, underlining issues inline.
Is Grammarly safe to use
Grammarly needs to read the text you type on websites to check it, which is expected for its function. Whether that is acceptable depends on your comfort with a writing tool processing text you enter online. Check the extension's privacy policy for how long text is stored and whether it's used to train models before deciding.
