Idea to finished book
An AI book generator should save you from the blank page, not hand you a stack of chapters you never chose. NovelGPT turns one idea into a full book setup, a chapter plan and drafted chapters, one at a time, with you steering.
No sign-up. 1,000 free credits every month.
Write your premise in a sentence or two on the Home screen. One request proposes title ideas, genre, length and chapter count, tone, the big question, story shape, cast, voice and readers.
Tap any line to change it and that field is pinned. Try another take re-proposes everything you have not pinned. Creating the book from the proposal costs nothing.
People, Places & world, Plot and the Chapter plan each arrive as cards marked New, Changed or Same. Nothing joins your book until you approve it.
Open a chapter and tap Draft this chapter. The text streams into the editor with a Stop button, and the price was on the button before you started.
After each chapter, Story memory can record the facts, open promises and a summary, so chapter 20 still knows what chapter 2 set up.
Asking a model for a whole 300-page novel in a single request sounds efficient. In practice the middle sags, names drift and the promise made in chapter 3 is never paid off, because no model can keep that many pages in view at once. A one-click book looks finished and reads as unfinished, which is why an AI book generator earns its keep by planning before it writes.
NovelGPT splits the job into pieces small enough to do well. The book is planned first and written a chapter at a time, and every chapter is written with the people, places, earlier events and open promises that matter to it. That is the difference between generating text and generating a book.
The setup proposal is a short spec sheet, not a wall of text. Each line is a decision a novelist would make anyway, and each one can be changed in a tap.
Nothing generates until you tap a button, and every button shows its price first. When the AI changes text that already exists, the change arrives as a suggestion to accept or reject, and a snapshot is saved before anything is replaced.
Ownership stays with you, AI-written passages included, and none of your writing is fed into AI training. You can start without signing up. On Free you start each month with 1,000 credits, and AI drafting is open for the opening 3 chapters of every book; chapters you type yourself never use credits.
In NovelGPT
One sentence becomes a genre, voice, length and a full Story setup you can change.
A whole chapter from your plan, streamed as you watch, with a Stop button.
Every chapter is turned into facts, threads and a summary the AI never forgets.
An outline for every chapter. Drag to reorder; numbers follow.
No, and that is deliberate. NovelGPT plans the book, then drafts one chapter at a time so you can read, change or stop at each stage. You can have the AI draft every chapter, a few of them, or none.
A chat window forgets what it wrote tens of thousands of words ago, so names, facts and promises drift. NovelGPT plans the whole book first and keeps story memory, so each chapter is written with the parts of the story that matter to it.
Each planning step usually takes one to three minutes. A drafted chapter arrives word by word, so you can start reading before it ends. The whole book takes as long as its length and your reviewing require.
You choose from Claude, GPT, Gemini and Grok models, and can use one to plan, another to write and a faster one for quick fixes. The Free plan runs on Claude Haiku 5.5 and GPT-6 Luna, and paid plans or credit packs open up the rest.
Per NovelGPT's terms the book is yours: your own writing and the AI's output both. You may publish and sell it, though some stores ask authors to disclose AI use, so check the rules wherever you publish.
Type your idea. NovelGPT will set up the book, and you write it your way.
