Die Rechtschreib-, Grammatikprüfung integriert sich nahtlos in den Browser, lässt sich gut an die eigenen Bedürfnisse anpassen und - da die App Open Source ist - kann man mit etwas Einarbeitung auch eigene Regeln schreiben.

LanguageTool Premium is just great. But I wish for a working LibreOffice plugin.

Love it

Alles genau richtig !

Très bon outil, y compris en langue française.

Espectacular complemento indispensable.

Very cheap(I'm on the premium plan), catches typos and the few grammar mistakes I make. Overall, I would highly recommend this extension if you want to make whatever you're writing as immaculate as possible.

It will work almost all the time when correcting your spelling, but many times it misses the grammar, hence not as polished as Grammarly.

Example:
OK, so I write the text, and it will correct me attempt (this sentence is correct according to LanguageTool

However, according to Grammarly it corrected my text to (OK, so I write the text, and it will correct 'my' attempt) which, I believe, is better.

There are many more cases where LT cannot detect the proper grammar. Also, I am on premium plan with ''Enhanced grammar, punctuation and style checking''. The only reason I use it because it helps me with additional language. Overall, it is decent for the job, but if you speak only English, then I don't recommend it.
