I quite like Grammarly on the PC, when I can get it to use English as opposed to Simplified English (US). I'm learning to live with its apauling predictive ability. But the worst thing is it comes but with a correction but doesn't mark in the text were the error is. It's normally so far behind you that you end up scouring paragraphs try to find the occurrence of the word it is objecting to. Oh, and it corrects between you presding Post and the text spoeafing where you as snt it.
