Linguix

Linguix is an AI grammar checker and writing assistant from Textly Inc that reviews and improves your text wherever you write: Gmail, Google Docs, Canva, ChatGPT and millions of other sites through its Chrome and Edge extension. More than 450,000 people use it, from freelancers to sales, marketing and support teams.

What does Linguix check?

It catches grammar, spelling, punctuation and style issues in seven languages (English, Spanish, French, German, Portuguese, Italian and Polish), detecting the language automatically. The rewriter reworks whole sentences to make them clearer, shorter or longer, and the content score rates each text by sentence length, vocabulary complexity and passive voice, which also helps when reviewing ChatGPT drafts.

What does Linguix offer teams?

Text shortcuts expand templates from a short command (such as "//intro") so you can answer emails or tickets faster. Style guides set how company names, job titles and terms should be written, and reports show error and readability stats per person. There's also an AI agent library, a Figma plugin, a white-label option and a grammar check API.

Linguix pros and cons

• Pro: it checks Spanish and six other languages, and its website is translated into Spanish.
• Pro: it works on almost any website with no copy-pasting.
• Con: the entry-level version is limited to basic checks and light paraphrasing, so heavier users will want Pro.
• Con: language coverage is narrower than checkers that specialize in one language.
