Perfect It

I am usually happy to rely on my own skills for editing and revising issues such as grammar, style, punctuation, etc.

Recently read a positive report on Perfect It. Sound good, but as it was unattributed (always raises a red flag in my suspicious mind) I thought I'd come here and ask:

I've downloaded the 30-day trial, so will check it out.

Can anyone comment on Perfect It?

Sorry! Don't bother replying to my original post.

Perfect It only works with Word, so it's of no use to me.
