Das Language Tool funktioniert recht zuverlässig in Hinblick auf die Orthografie, die Grammatik-Hilfe ergibt bisweilen recht abenteuerliche Vorschläge. Ich rate all jenen Mitbürgern dringend zur Installation, die bar jeglicher Bildung aggressiven Unfug, Beleidigungen und extremistische Hetze in die sozialen Netzwerke posaunen.

Not very good at the Basic level. Hard core sales to upgrade to the paid level. I already use Grammarly.

Ich finde das eine prima Sache und wirkliche Erleichterung.

Great except it keeps on pushing premium only issues in my face, honestly ruins it.

Heute im ersten Test : ich bin begeistert

Works quite well, but the red warning message with supposedly further errors found, which you can only see in the premium version, makes the tool useless and confusing. Deleted.

Only Portuguese from Brazil is available.

I downloaded it because it advertised itself as working for multiple languages. While it did appear to work fine for English and French, it unfortunately failed to catch basic Japanese grammar mistakes such as missing particles and misspelled words. Given that I need this most for Japanese (as that is my weakest language at the moment), I have decided to remove it from my browser.

Early days for me but it seems to do a reasonable job.
