Complex revisions, done in minutes.
Move a scene to another chapter. Carry a new rule of your world through every chapter it touches. Cut the subplot that stopped working. Say what should change, and the chat does the work.
It lays the changes out first, chapter by chapter, beside the conversation. Skip any you don't want, then say go. Your old draft is kept, so a revision is never a leap without a net. And when the book is done, it can translate it for you, chapter by chapter.
Describe your idea. Get a chapter plan.
Tell the chat what your story is about, as loosely as you like. It asks about what's missing, then lays the chapters out beside the conversation.
It never invents your story: where the idea leaves a gap, it asks instead of filling it in. The plan comes sized to your genre and your target length, with notes and characters in every chapter.
An assistant by your side.
Can't remember in which chapter your leads fight? The chat finds it and opens the chapter beside the conversation. No scrolling, no search box.
Write and discuss ideas in a single screen. Ask for a line edit and it runs one. The notes land under the chapter, each beside the passage it's about, and nothing changes until you press Apply.
Your world, in clean sheets.
Talk through a character, a city, a magic system. The chat files what you decide into your world bible, one sheet per character, place and term.
So your ideas don't get lost in an endless scroll of messages. Open any sheet beside the chat, and the chat reads them before it answers, so it remembers what you decided.
