I use Language Tool for 99% of my writings. in English as well as in German. I recommend it for everyone!

Very good, detects the language easily and while some of the stuff is behind a paywall, it does what it's supposed to do without having to work extra.

esta muy bueno

Tenho usado com frequência o LT e com bons resultados. Tem me ajudado muito na redação de textos. Superou a minha expectativa embora algumas vezes eu tenha recusado suas sugestões porque se tratariam de questões de estilo. Nestes casos o LT não teria gostado do meu estilo.

Suddenly stopped working on FF but continues to work on Chromium based browsers.

Das beste Recht schreibe Programm, das ich kenne. Einfach super.

Ein fantastisches Werkzeug, das sogar Logikfehler wie ein nicht mit dem Wochentag zusammenpassendes Datum findet. Fünf Sterne sind dafür eigentlich noch zu wenig ;-)

Magnifico, extraordinario y de gran utilidad.

zeer waardevol

This grammar checker is highly advanced, however, Grammarly is a much more sophisticated, but I think it is important to support them, and hopefully improve them

LT hilft mir im täglichen Gebrauch und ist ein toller Assistent bei der Rechtschreibprüfung.
