Build a series bible
Create one world, approve a recurring cast, then start book two with both attached. Continuity becomes structural instead of something you have to remember.
One World + the same characters, every book.
From one idea to a finished book
Magic Fiction Writer walks your idea through four steps — your synopsis, your characters, your chapter outline, and your finished book — and lets you approve or rewrite every one of them. You end up with a real, multi-chapter book. And it still sounds like you.
10 free credits every day. No card to get started.
See how it actually works
Two minutes, start to finish: type an idea, approve your synopsis, approve your cast and outline, and watch the chapters come in.
Four steps. You approve every one.
Most AI writing tools give you one giant button and one giant blob of text. This one builds your book the way a book actually gets built — one layer at a time, with you signing off before it moves on. Some of the heavy lifting runs on our servers between steps, so there's never a screen you have to sit and watch.
- 1
Your synopsis
We take your title, description, genre, and chapter count and write the full story: premise, arc, stakes, ending. This is the blueprint everything else is built from, so it's the highest-leverage thing to edit. Read it, change anything you like, approve it.
- 2
Your characters
The app reads your approved synopsis, pulls out everyone who appears in it, and writes each of them a full bio — background, motivation, voice, relationships, and their job in the plot. Anyone you brought in from your library is recognized, not duplicated. Edit any of them, then approve the cast. Approved characters go into your library and can headline your next book too.
- 3
Your chapter outline
The architecture of the book: act breaks, turning points, every subplot's through-line, and a chapter-by-chapter plan that maps onto the chapter count you chose. Adjust anything that feels off, then approve it — your whole book gets written from this.
- 4
Your book
Now every chapter gets written. The app first expands your outline into a detailed plan for each chapter, then writes the prose, with live progress the whole way. It all runs on our servers — close the tab, make dinner, come back. If anything gets interrupted, it picks up where it left off. When it's done you can read, copy, or download the finished book.
Two parts of this run on their own — finding your characters, and planning each chapter in detail. You'll see the progress; you don't have to do anything.
You're the editor, not the audience.
At every step you can approve it, rewrite it by hand, or regenerate it. Your edits become the source of truth for everything after — so rewriting the synopsis in step one genuinely changes the chapters you get at the end.
Don't take our word for it. Take three genres.
Same app, same four steps, wildly different books. Here's what it sounds like when you point it at horror, romance, and a thriller.
Dread that builds chapter over chapter.
Tension, longing, and a payoff that's earned.
Plot machinery that actually clicks together.
Your genre isn't in the list? Type your own. The app doesn't have a fixed menu.
The part that makes book two easier than book one
Anyone can generate a one-off. What makes this a studio is everything that carries over.
A cast that outlives the book.
Every character you approve goes into a library that belongs to you, not to one story. Pull them into the next book from the setup screen and they show up with the same bio and the same voice. Search them, sort them, filter them by story, view them as cards or a list, edit any of them by hand, and build new ones from scratch. Your characters are private to your account — nobody else sees them.
Attach up to eight characters when you start a story and they're required to appear in the synopsis. They don't quietly get dropped.
One world. One voice. Every book.
A world is a reusable document holding everything true about a setting — geography, factions, history, the rules of magic or technology, tone, and whatever notes you want. Build one by hand, or paste in your existing notes and let the app structure them for you. Attach it to a story and every step respects it.
A writing style captures voice: person, tense, sentence rhythm, diction, humor, density. Write one yourself, or paste about a thousand words of prose — yours, or an author you're studying — and the app extracts a reusable style profile from it. Attach it and the voice is enforced all the way through to the final chapter.
And if you don't attach a world? Generation stays deliberately genre-neutral. It won't wander off into generic fantasy just because you left the box empty.
A shelf, not a folder.
Every story gets its own cover in a grid you can actually browse — genre, chapter count, status, last edited. Finished books get a gold seal. Flip to a compact list when you have a lot of them, and the app remembers which you prefer. A shortcut strip drops you straight back into whatever you were last working on.
Up to 20 chapters
Real books, not blog posts. Set the length up front and the structure adapts to it.
Custom genres
Pick a preset or type your own. Cozy space-western noir is a genre if you say it is.
Nothing gets lost
Chapter planning and chapter writing both run on our servers, with live per-chapter status and a resume button. Close the tab whenever you like — your progress is saved.
Edit anything, anytime
Hand-edit any step's output. Your version wins and feeds everything downstream.
No machinery on screen
Four plain-English steps, a status line that always tells you what's happening, and no jargon. The complicated parts happen where you don't have to watch them.
Things people actually do with it
Most people start by writing one book. Here's where it goes after that.
Ghostwrite in your own voice
Paste a thousand words you actually wrote into the style analyzer and save the result. Attach it to everything you generate and the output reads like you.
Worlds & Styles → Writing Styles → analyze a sample.
Run a style bake-off
Write one synopsis, then start three stories with the same premise and three different saved styles. Compare the openings and keep the one that sings.
Same idea, three styles, three stories.
Serialize bedtime stories
Short chapter counts, a recurring hero pulled from your library, one chapter a night. A brand new book every week with the same beloved cast.
4–6 chapters, same characters, repeat.
Use it for pre-production
Stop after the outline. Your approved chapter outline is a perfectly good beat sheet for a screenplay, a comic script, or a narrative game. You never have to generate prose at all.
Approve the outline, then stop.
Teach story structure
Walk a class through synopsis → characters → outline → chapters as a live demonstration of how a book is assembled, editing each step together.
Project it and edit each step as a group.
Simple credits. Start free.
Free every day
You get 10 credits every single day, resetting at midnight UTC. They're yours whether you use them or not — enough to explore, outline, and start writing without paying anything.
What things cost
Story generation is 5 credits per chapter, so a 12-chapter book is 60 credits. Analyzing a writing sample or generating a world from pasted text is 2 credits. The cost is shown on the setup screen before you commit to anything.
When you want more
Buy reserve credits, subscribe for a monthly top-up, or grab a lifetime deal. Reserve credits are only touched after your free daily allowance is spent, so nothing goes to waste. Got a promo code? Redeem it in your profile.
Lifetime deals stack. Hold two and you get two monthly credit allocations, each on its own date — not one merged into the other. There's also a one-time upgrade that permanently raises your daily free-credit limit.
