The best grammar option for multi language

I Tried this extension in Chrome, and now on safari it's pretty useful if you write in multiple languages and want to have a clean grammar. Their dictionary is pretty good. Also the UX is very nice. I hope you keep improving this Safari version.

Good Grammar Checker

I am grateful to find a grammar checking option native to macOS for Spanish. The app is very basic and does a good job of finding rudimentary errors that this beginner of Spanish makes.

This app is disappointing in its lack of features. Having used Antidote 10 for English and French has shown what a grammar tool can be, and has soured me to all other options. If Antidote added Spanish, I'd pay any sum within reason to purchase it and discontinue LanguageTool.

Una aplicación esencial

Genial. Esta aplicación es esencial para cualquier escritor, bloguero, periodista, estudiante… en realidad, para cualquier persona que desee verificar, corregir y mejorar su escritura. Las distintas opciones para crear y corregir un buen texto la hace excelente. Para mí, lo mejor es que la aplicación/extensión es compatible con el castellano (o español).
