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.

Ótimo. Mas, é uma pena que ele só funcione com a linguagem mais formal. ele não reconhece gírias e linguagens usadas mais comumente no dia a dia.

This is the most amazing spell checker and useful add-on on the internet. Good onya Firefox! Thanks.

I think It's better than Grammarly.

This add-on works very well for me. The comma suggestions are just what I was looking for :).

Works great, and has great features, recommended.

Ich bin hochzufrieden mit dem tool. Es hilft mir auf vielen Seiten die ich bearbeite.
Vielen Dank

Es un corrector excelente y me ha evitado publicar con errores gramaticales, imperdonables. Lo recomiendo.
