Hemingway App makes your writing bold and clear.
The app highlights lengthy, complex sentences and common errors; if you see a yellow sentence, shorten or split it. If you see a red highlight, your sentence is so dense and complicated that your readers will get lost trying to follow its meandering, splitting logic — try editing this sentence to remove the red.
You can utilize a shorter word in place of a purple one. Mouse over them for hints.
I could see some serious value in this if I could use it as a web app with Micropub support, which would allow it to almost any CMS or platform. It’s a bit reminiscent of Quill, though that doesn’t have the grammar and writing help.
There’s a $20 desktop version that can publish to WordPress and Medium.
Possibly missing for a full editor experience: the ability to add images.
As a sample, I tried putting in some prior writing. Apparently I overuse adverbs. It said I was writing at grade 13 and I should aim for grade 9! (It was something I had already attempted to “dumb down”.)
