Open your ProWritingAid desktop app, click "File," then click "Open File." 2. Select your Scrivener doc from the menu and it will populate within the ProWritingAid app. 3. If your formatting looks different, don't worry—the desktop app ignores formatting while you're editing, but retains it in your original Scrivener doc. 4. When you're done making edits, click "Save" and all those edits will be synced back to your original Scrivener doc.
