Linguix checks grammar, spelling and punctuation as you type on websites in Chrome and suggests rewrites and paraphrases. It is meant for people writing emails, posts or longer documents in several European languages who want cleaner text.
After installing, start typing in a text field on a website; Linguix underlines issues and you click a suggestion to apply it or open its rewrite options.
Text you write is analysed by the developer's service. Check its Chrome Web Store page for current terms.
