Rewriting with AI
To rework a passage with AI, highlight it and pick an action from the Highlight Bar that appears. Quarkle previews the change as a diff and you accept it only if you like it. See the Highlight Bar for the full set of one-click rewrites. To write forward from the end of a chapter, press the pink quill. Ghostwriter reads the current ending and continues it directly on the page.Every keystroke is captured as you write. Learn how Quarkle checkpoints your work in version history.
