Pros & cons of Linguix
A cheaper Grammarly substitute whose two genuinely interesting features are not what it leads with: non-English checking and a grammar API you can embed in your own editor. As a pure English writing assistant it trails the market leaders.
Pros
- multi-language checking that most English-first rivals do not match
- documented API with a free 1M-character tier for evaluation
- text-expansion shortcuts bundled instead of sold as a separate tool
- two-year plan brings the effective price down to about $10/month
Cons
- a permanent 50%-off banner makes the real list price hard to pin down
- team and business pricing is not published anywhere on the site
- very small company — headcount reported in the low single digits in 2026
- English suggestion quality does not match Grammarly or LanguageTool Premium
Best for
- writers working in French, German, Spanish, Portuguese, Italian or Polish
- developers embedding grammar checking into their own product via API
- teams enforcing one style guide across support and sales writing
- heavy users of canned replies and text snippets
Not for
- people who want the strongest available English suggestions
- document-level AI drafting or long-form generation
- desktop-first or offline workflows
Watch out: The advertised 30+ language support belongs to the developer API — the consumer extension covers seven languages.
