Don't you love it when you find a new tool to make your work easier? One of the benefits of teaching is I also learn from the course participants.
It's Hemingway that has my attention this time (thanks to Jacqueline). I love it's simplicity! Go to hemingwayapp.com and start typing right on the screen. You'll see suggested edits highlighted as you type. Or you can turn off the editor until you're finished writing and do all your editing at the end. Another bonus for bloggers is you can see your stats: reading time, letters, characters, words, sentences and paragraphs.
Start writing your next article using Hemingway and see what you think.
