AI novel generator

Generate a full-length novel draft from a two-sentence pitch

FictionAI plans the novel first (premise, world, cast, chapter outline) and then writes it one chapter at a time, each chapter written from that plan and the chapters before it. You edit everything along the way.

Built for novel-length fiction

  • Plan before prose

    One action builds premise, title, world, cast and a chapter-by-chapter outline. Edit any card or regenerate it with an instruction.

  • Chapters that follow the plan

    Each chapter prompt includes the story bible and the saved text of earlier chapters.

  • Genre defaults

    25 listed genres, or type your own. The genre pre-fills point of view, tense, tone, story shape, themes and tropes.

  • Write all remaining chapters

    Queue the rest of the book; chapters are written one at a time and you can stop at any point.

  • Series

    On Pro ($9.99/month), plan sequential, standalone or mixed series with a shared world and cast.

  • Your model, your cost

    Choose Fast, Balanced or Best, or any OpenRouter model per task. You see the estimated and actual AI cost of every chapter.

Questions

How long of a novel can FictionAI generate?

Pick Short story (~10k words), Novella (~30k), Novel (~75k) or Epic (~125k). The length sets the number of outline chapters, and you can add or remove chapters.

Does the AI maintain consistency across chapters?

FictionAI builds the world, cast and outline before any prose, and each chapter is written with that story bible and the earlier chapters' saved text in the prompt. It still makes mistakes; editorial review gives book-wide feedback, and you edit.

What genres does the novel generator support?

25 listed genres, including Fantasy, Science Fiction, Mystery, Romance, Thriller, Horror, Historical Fiction, Literary Fiction, Young Adult and Western, or any genre you type. Listed genres pre-fill point of view, tone, story shape, themes and tropes.

Can I generate a novel series?

Yes, on Pro. A series is sequential, standalone (same universe) or mixed, with its own outline, cast and world; each book in it is planned with the series world and cast as context.

How fast can I generate a complete novel?

Chapters stream into the editor as they are written, and "Write all remaining chapters" writes them one after another. The time depends on the model you choose and the length of the book.
