Linguix is an AI-based writing assistant developed by Textly Inc. that checks grammar, punctuation, and spelling and suggests style improvements as users type. It supports writing in seven languages: English, French, German, Spanish, Portuguese, Italian, and Polish. Alongside corrections, Linguix includes a text rewriter that paraphrases sentences to make messages clearer and more effective, and a content score that evaluates text quality based on factors such as sentence length, vocabulary complexity, and passive voice usage.
Productivity features include typing shortcuts that expand short commands into reusable templates for emails and social media replies, which the company says can cut repetitive typing time by up to 90 percent. For businesses, Linguix offers style guides for consistent corporate communication, team management, and analytics that report on employee writing activity and improvement.
Linguix runs as browser extensions for Chrome, Edge, Firefox, Safari, and Opera, and as a web editor. It works inside popular web apps including Gmail, Google Docs, and Canva, offers a Figma plugin, and provides an API for developers. The company reports more than 450,000 users.
A free version provides basic corrections and free tools such as a grammar checker and AI content detector. Linguix Pro, which unlocks paraphrasing, advanced corrections, and shortcuts, is priced at $30 per month, with discounted annual ($140/year) and two-year plans. A separate Business plan is available for teams of two or more.
