One of the very best anywhere among language support! You can't go wrong, choosing this one.

I truly love this add-on. Thanks for the recent sale, I've upgraded to Premium. I can imagine that this app requires much work and maintenance.

Molto affidabile (nessun falso positivo, che io ricordi). Ottimo supporto multilingue. La lingua usata viene riconosciuta automaticamente (molto comodo!). Se proprio devo trovargli un difetto (che i pregi sorpassano di gran lunga): l'interfaccia mi sembra un tantino ingombrante, p.es. non di rado la finestra mi si apre involontariamente.

És un corrector molt pràctic i fiable, que em fa la vida més fàcil. Si tries el modo perfeccionista, pots editar textos de bona qualitat.

Japanese version is completely useless lmao

Exclente

A minha experiência até agora está sendo ótima, a extensão me ajuda muito no meu dia à dia.

Sadly no Indonesian, Javanese, and Balinese language option in this spell checker extension.

Super Tool, kann ich nur empfehlen

A perfect, FOSS tool, that I believe is better than things like grammarly. It is amazing how well it works. Nit-pick mode and the recent addition of synonyms really help when you quickly need to get work done and are a bit too frazzled to do the lifting yourself.
Even for my weird language, the grammar and nit-picking is on point. Highly recommended, I pay for the full service (though I do not strictly need it) to support this great initiative.
