LanguageTool

What it does

LanguageTool checks what you type in Chrome for spelling, grammar, punctuation and style problems across more than two dozen languages. It suits native and non-native writers who want corrections in email, social posts and other web text fields.

Key features

• Flags grammar slips, confused words and punctuation issues that a basic spell checker misses
• Checks text as you type on most sites, including Gmail, LinkedIn and other social networks
• Suggests synonyms for overused words, shorter phrasing and more formal alternatives
• Tells apart language variants such as American and British English
• Keeps a personal dictionary for names and terms you use often

Use cases

• Proofreading an email or job application before sending it
• Writing social posts or comments in a second language
• Tightening wordy sentences in a blog draft

Getting started

After installing, start typing in a text field on a website and LanguageTool underlines issues; click an underline to see and apply a suggestion. The developer says no registration is needed for the basic checker.

Good to know

The text you write is checked by the developer's service, so avoid using it on content you cannot share. Check its Chrome Web Store page for current terms.
