Chapter three
The lamp room
Mara closed the door against the wind and stepped slipped into the warm hush of the lamp room.
Three AI editors had left suggestions overnight — each one waiting for her yes or no.
Made for long-form writing
Chapters, outline and review stay together while AI editors leave suggestions you can keep or skip.
-
Suggestions, never rewrites
Every AI edit shows up as a tracked suggestion. Accept what helps, reject what doesn’t — your manuscript only changes when you say so.
-
Your book stays on your computer
Saves as you go; the original Word file is never changed. Your chapters and settings stay on your PC, not in someone else’s cloud.
-
Bring your own AI editor
Connect editor bots safely; each gets its own key, nothing leaves your machine. You choose which tools work on your book.
