Writeable for Mac has an easy to use text input area, available anytime from the Mac top menu bar. You copy text from your main document and paste into Writeable. 



Once the text is within Writeable, you can then choose the Writeable commands to generate a commentary on the text, and some suggestions for re-writing or improving. Writeable will not change your original text automatically. This is by design, to help you improve your own work.
