What is Linguix?
Linguix is a grammar checker and AI writing assistant that corrects spelling, grammar, punctuation and style in seven languages. It runs mainly as a browser extension, so it checks text in Gmail, Google Docs, Canva and most other websites. It is built for freelancers, professionals and teams who write a lot of short-form text online.
Alongside corrections, Linguix offers a rewriter that shortens or expands sentences, a Content Score that rates readability, and text shortcuts that expand short commands into full templates. Business teams can set style guides and view writing reports. The product is made by Textly Inc., which also offers a Grammar Check API and a Figma plugin.
