I have been looking for a decent grammar auto-correct for the last 10 years for Firefox... now i finally found one that doesn't auto correct but does the job it is supposed to, and does it very well I will say

Fucking excellent. Just amazing. Bravo!

Besser als alle Rechtschreibtools, die ich bisher hatte. Ich habe nur die kostenlose Version, bin trotzdem sehr zufrieden.

Very nice tool. Strange that I was brought to a site for human/bots verification a few days ago. For people who having the same problem, just try it another day.

Excellent correcteur, je suis positivement étonné, bravo

It's great because I am not so great at grammer.

sencillamente magnifico

cool, cool, cool. especially for a spelling challenged mis-fingered non keyboard user

just perfect I really hope everything in my life work like that
