What is Linguix?
Linguix is an AI writing assistant from Textly Inc. that checks grammar, spelling, punctuation and style as you type. It runs mainly as a browser extension, so suggestions appear inside sites such as Gmail, Google Docs and Canva, and there is also a web editor. Checking covers English, German, French, Spanish, Italian, Portuguese and Polish, with the language detected automatically. Beyond corrections, Linguix can rewrite whole sentences, shorten or lengthen a message, and expand saved text snippets from short commands. A content quality score rates a text on factors like sentence length, vocabulary difficulty and passive voice. For companies, Linguix Business adds style guides, role management and per-member writing statistics. A grammar check API and SDK are available for developers, and a free plan sits alongside the paid Pro subscription.
