Click here or on the above word cloud for a 90-second run-through of The Hemingway App, an online pair of eyes [creepy, I know] that points out [without browbeating] a writing flaw or two.
Here is an opening sentence I used on another blog…and Hemingway’s feedback. [That hack…I’ve heard he claims to have written The Sun Also Rises and A Farewell to Arms.]
You just paste in your masterpiece and out comes the quick but helpful evaluation.

There is also a $20 desktop version.
Note: Thanks to websiteplanet.com for reminding me about The Hemingway App and a few other helpful tools.
