Editing software can't replace a human editor, but if you present him with a well-edited, highly-polished text, an editor will be able to focus on your content and ideas rather than your syntax and word choice.
Self-editing can be harder than writing because we grow to love our creations, and we often have difficulty seeing them objectively. We have a hard time destroying the little superfluous bits that keep our manuscripts from greatness because it feels like we’re destroying pieces of ourselves.
An editing tool uses powerful algorithms to compare your content with that of thousands of published authors. It finds where your writing is clunky or awkward and helps turn your prose into a dynamic, compelling piece that gets readers' attention.
Like any craft, the beauty of writing lies in the creative process combined with the workmanship and joinery that lie beneath the surface. So writers, don’t panic! You’re not out of a job. Apple’s next major innovation is not going to be the iTolstoy. Please carry on writing wonderful stories for us to read. But, while a computer program can’t generate a compelling narrative or sympathetic characters, it might help make a good story even better. It's where technology can make a difference.
