NovelGPT Open the app

Like ChatGPT, but for writing books.

The AI novel writer that never loses the story.

Write a book with AI that plans, drafts and remembers every page, from the first idea to the finished book. A novel writing app that works as a planner, a drafting partner or a quiet editor: nothing changes your book until you accept it.

No sign-up. 1,000 free credits every month.

One app, every step

One AI for every step of your book.

An AI book generator, a story generator, an outline builder and an editor, all in one place and all sharing the same story memory.

  • AI book generator

    Turn one idea into a whole book: title ideas, genre, length, people, places and a chapter plan, then chapters drafted as you watch. You approve every step.

  • AI story generator

    Stuck for an idea? Brainstorm premises, try an example, or type one sentence and get title ideas, a big question and a story shape to build on.

  • Book outline generator

    Pick a story shape such as three-act, Save the Cat or the Hero's Journey, and get key moments and a chapter-by-chapter plan you can drag into order.

  • AI character generator

    People who want something, wrongly believe something and need something else, each with a voice of their own and a web of relationships.

  • Story bible & world building

    Places, rules, facts and promises live in one story bible the AI reads before it writes, so chapter 30 still remembers chapter 3.

  • AI editor & plot hole checker

    Free checks catch name typos and timeline slips, the consistency check quotes both pages when the story contradicts itself, and nine edit passes polish the rest.

  • AI book cover generator

    Start from a genre template, let the AI paint the art from your story, and export a cover sized for Amazon KDP and other stores.

  • Finish your novel with AI

    Import a Word, text or PDF manuscript. NovelGPT finds your chapters and maps your story, so the AI can help you revise and finish it.

Start with an idea

One idea in. A whole book plan out.

Type your story idea in a sentence. NovelGPT suggests the genre, voice and length, then builds your people, places, key moments and a chapter-by-chapter plan. You approve every piece.

Write with AI

Watch your chapter write itself.

Draft a whole chapter from your plan, write on one scene at a time, or polish a single paragraph. Every AI change arrives as a suggestion you accept or reject, and the price is shown before it starts.

Our consistency engine

The AI that never loses the story.

Story memory keeps track of who knows what, who is where and every promise you have made the reader, chapter after chapter. It catches slips before your readers do, and quotes both pages so you can fix them in one tap.

See the whole book

See your whole novel. No more writing blind.

The Book map shows every chapter at a glance: acts, key moments, rising tension and who appears where. The timeline follows events in story time, flashbacks included.

Already writing?

Bring your draft. Finish it here.

Import a Word, text or PDF manuscript. NovelGPT finds your chapters and can map your people, places and plot, so the AI helps you revise and finish the book you started.

Every device

Write anywhere. Pick up where you left off.

Sign in and your books follow you across iPhone, iPad, Android, Mac and the web. Start a chapter at your desk, add a scene on the train, finish it on the sofa: your chapters, people and notes are waiting on whichever screen you open next. Signing in is free and optional.

Your cover

A beautiful cover in minutes.

Start from a genre style, then let the AI paint the art from your story. Change the title, fonts and colours, and export a cover sized for every store.

Ready for readers

From first line to finished book.

Add front and back pages, then export to EPUB, DOCX manuscript format, PDF, Markdown or plain text. You own every word, your writing is never used to train AI, and you can start without signing up.

Questions writers ask

Is NovelGPT free?

Yes, to start. The Free plan includes 1,000 credits every month and you can write by hand for free, as much as you like. On Free the AI writes the first 3 chapters of each book; paid plans and credit packs add more AI when you need it.

Do I need to sign up?

No. Open NovelGPT and start writing; your books are saved on your device. Sign in only if you want your books on your other devices too.

Can AI write a whole book?

Yes, chapter by chapter, and as much or as little as you want. NovelGPT can set up the book from one idea and draft every chapter from your plan, write on a scene, polish one line, or stay quiet while you write every word. Nothing changes your book until you accept it.

How is NovelGPT different from ChatGPT for writing a novel?

A chat forgets what happened forty chapters ago. NovelGPT keeps your people, places, plot and every chapter in story memory, gives each writing action the parts that matter, and checks new chapters against the old ones.

How does it keep the story consistent?

Story memory reads each chapter and keeps facts, promises and summaries. Every writing action is given the people, places and earlier chapters that matter, and checks quote both passages when something doesn't match.

Which AI is best for writing a novel?

The one that suits the job, so you choose. Pick models from Claude, GPT, Gemini and Grok: a stronger one to plan and draft, a faster one for quick fixes. Free credits cover Claude Haiku 5.5 and GPT-6 Luna, and the cost is shown before every action.

Who owns what I write?

You do, including the text the AI writes for you. You can publish and sell your book. Your writing is never sold and never used to train AI models.

Can I publish a book I wrote with AI?

Yes. Export EPUB, DOCX in standard manuscript format or PDF and publish wherever you like. Some stores, Amazon KDP among them, ask you to say when text or images were made by AI, so check their current rules before you publish.

Does it work for nonfiction?

Yes. Memoir, self-help, narrative nonfiction and more are among the 28 genres, each with its own structure and style.

Can it write a novella or a shorter book?

Yes. Pick a length from a novelette or novella up to an epic novel, and the chapter plan and every draft follow it.

Can I bring a book I've already started?

Yes. Import a Word, text or PDF file and NovelGPT finds your chapters. If you want, it maps your people, places and plot so the AI can help you finish it.

Can it make my book cover too?

Yes. Start from a genre template, let the AI paint the art from your story or use your own image, and export a cover sized for Amazon KDP. Each AI image shows its price before it starts.

Your next novel starts with one sentence.

Type your idea. NovelGPT will set up the book, and you write it your way.
