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.
3 books free, no credit card. AI use is billed by OpenRouter to your own account.
Pick a length
The length sets the chapter count of the outline. You can add or remove chapters afterwards.
| Length | About | Chapters |
|---|---|---|
| Short story | 10,000 words | 5 |
| Novella | 30,000 words | 12 |
| Novel | 75,000 words | 24 |
| Epic | 125,000 words | 36 |
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.
Why a novel generator instead of a chatbot
| Problem in a chat window | What FictionAI does |
|---|---|
| Earlier chapters drift out of view | Each chapter is written with the story bible and the earlier chapters' saved text |
| Characters change between sessions | The cast lives in the story bible, where you edit it |
| Copy-pasting chapters out of a chat | Export the manuscript as DOCX, PDF, Markdown, plain text or HTML |
| World details get lost | Setting, locations and world rules sit on one card that every chapter uses |
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.
