Fnny…as a reminder tool,ok

the check result is funny… the sentence "we notice” is suggested as “we note “. Here is the fun part: when I correct my sentence and review again, the suggestion is ”we notice…” R U KIDDING??????

It does not open

I wish that the program would stay open long enough so that I could see it. It reliably crashes. I wish that it worked.


Compared to Grammarly’s free version of their software this detcts so much more!
