Overview

Linguix is a comprehensive AI writing application and grammar checker designed to supercharge written communication across any website and browser. It enables individuals and teams to create texts that are grammatically correct, clear, and highly effective in real time. The product combines a browser extension, a web editor, and integrations such as Figma, providing a lightweight layer of intelligence wherever users type. Trusted by more than 450,000 users and featuring prominently in the Chrome and Edge stores, Product Hunt, and G2, Linguix positions itself as an enterprise-ready solution for improving written output without forcing users to change their existing workflows.

At its core, Linguix offers multilingual grammar and spell checking that automatically detects the language of the content and generates suggestions for improvement. Supported languages include English, French, German, Spanish, Portuguese, Italian, and Polish. Its AI-based writing assistant delivers grammar, punctuation, and style recommendations, helping teams ensure no mistakes slip through. The built-in Text Rewriter can instantly rewrite whole sentences to fix errors, shorten or expand messaging, and improve overall copy quality. For measurable quality control, the Content Score feature analyzes sentence length, vocabulary complexity, and passive voice usage, assigning a score that can be benchmarked against content generated by tools such as ChatGPT.

Linguix also includes productivity-oriented features that are particularly valuable for business environments. Shortcuts allow users to create reusable templates and expand them with one-word commands such as "//intro," reducing the time spent on email and social media writing by up to 90%. Style Guides help organizations enforce consistent, polite, and inclusive corporate communications, ensuring that event titles, executive names, and positions appear professional across all materials. Team Management dashboards provide performance stats, error counts, readability scores, and email reports for each team member, enabling early identification of communication issues and supporting data-driven coaching.

Designed for multiple business verticals, Linguix scales from personal use to full team deployment. Sales teams leverage the intelligent paraphraser to craft compelling introductory messages and proposals; marketing teams maintain error-free, audience-targeted copy; and customer support teams use the Turbo app to create shortcuts that deliver consistent responses and close tickets faster. With a clean interface, high approval ratings in usability and support, and availability on millions of websites including Gmail, Google Docs, OpenAI, and Canva, Linguix serves as a practical AI assistant for anyone looking to elevate the quality and efficiency of their written communication.
