AN AI WRITING APP FOR NOVELISTS

Novel Writing App

A novel outgrows a document. Keep chapters and notes in one project, open it on a laptop, tablet or phone, with an AI agent that works across the whole book.

A working title or one line about the story is enough.0/500
01

Tell Muses what you’re writing

A working title, a genre, or the scene you keep rewriting. Muses opens a novel project around it, so the first thing you see is your own book and not a sample one.

02

Look around your own project

Chapters down one side, folders for characters, worldbuilding, your outline and references, the draft in the middle and the AI next to it. Add a chapter, drag it into order, ask the AI to look something up.

03

Come back on another device

Sign in from a laptop, a tablet or a phone, open the project and you are back at the chapter you last worked on. Nothing to move across, nothing to sync, no second copy to keep track of.

Look inside before you sign up

An interactive demo of the editor: open a chapter, browse the story folders and see how a suggested edit is marked in the text.

After the Tide
The day Wren came back to Saltfog, fog rolled in off the water. By the time the ferry touched the pier, all she could see of the lighthouse was its outline, like a candle someone had blown out halfway through.
She climbed the stone steps. They were old, every one of them worn to a shine by generations of keepers, with small wet moss growing in the cracks, so that you had to be careful where you put your feet. She went slowly, and as she went she remembered being small, her grandfather holding her hand, when her legs were short enough that each step took two of her own.
+She climbed the steps that generations of keepers had worn to a shine. As a child, her grandfather holding her hand, each one had taken two strides; now it took one, and she was faster than her memory of it.AcceptReject
The lamp room door was not locked. She turned the brass handle, pushed it open, and felt along the wall for the old switch. She paused for a moment. Then she pressed it, and the lamp came on.
The beam swept the water and turned the fog a dirty white. She understood, suddenly, why her grandfather had never agreed to move down into town. Up here you were the only person who could make the night step back.
Footsteps came from below, light ones, stopping halfway up the stair. Wren did not turn around. She had known the town would come sooner or later. She had not expected the first of them to walk so quietly.

The first two paragraphs drag. Tighten them, and when the lamp comes on, give me one concrete sensory detail.
Read complete[Article]Chapter 7 · The Lamp Room· 14 blocks

I've read all 14 blocks of the chapter. The first two paragraphs both set up weather and the stairs, and they repeat each other; the first real action, her opening the door and pressing the switch, doesn't arrive until paragraph 3.

I’ll make three edits: cut paragraph 1 to the ferry and the lighthouse outline, fold the stair memory in paragraph 2 into one contrast, and add a single touch or smell to paragraph 3 as the lamp comes on.

You've accepted the first one; the second is marked in the draft for you to accept or reject. For paragraph 3 I'll add a single sentence and leave your pacing alone.

What to look for in a novel writing app

It opens wherever you write

Muses runs in a browser, so the same novel is there on a laptop, a tablet or a phone. On a phone or tablet, add it to your home screen and it opens in its own window.

It holds the whole book

Not one file that keeps growing. The book is a list of chapters, and the story material — characters, worldbuilding, outline, references — sits one click from whichever chapter is open, instead of in another app you have to go and find.

Its AI works across the whole manuscript

The AI is an agent inside your project: it can search the whole manuscript, read the chapters and story notes a scene depends on, then draft or revise the exact passage with timeline, point of view and foreshadowing in mind. It keeps project memory between sessions, and edits to your text arrive as suggestions you accept or reject, saved as a version.

What writing a novel puts an app through

Four things a long draft will ask of whatever app you pick, and how each one works here.

A manuscript that outgrows one file

By chapter twenty a novel stops being a document and becomes a structure. Chapters live in a list you can rename, reorder and group into folders for parts or volumes, so reaching chapter fourteen is one click instead of a long scroll — and the outline can be a mind map when a list stops helping.

Story notes you can find mid-scene

You need the name of Mira’s first teacher in the middle of writing their argument. Character sheets, worldbuilding and timelines stay in the project’s folders, and you can ask the AI to check them for you without leaving the chapter you are in.

Days the words will not come

Start the writing timer and it reports the net new words from that session, including anything you kept from the AI. When you cannot get into a scene, ask for a way in: “Read chapter eleven and Mira’s notes on the border survey, then suggest three ways this scene could open.”

Getting the manuscript in and out

Bring in what you have already written as DOCX, TXT or Markdown — a single file, a folder or a ZIP — and export whenever you like as DOCX, Markdown, TXT or PDF, either as one merged file or a ZIP that keeps your folder structure.

Practical questions before you start

Which devices can I write on?
Any device with an up-to-date browser: a computer, a tablet or a phone. The same project opens on all of them. Long drafting sessions are more comfortable on a bigger screen, where the chapter list, the draft and the AI are all visible at once; a phone is better for reading a scene back, fixing a line or reviewing an edit on the way home.
Do I need to download anything? Is it in the app stores?
No to both. Muses runs in your browser, so there is nothing to install and nothing to update, and it is not listed in the mobile app stores. On a phone or tablet, open it in the browser and add it to your home screen from the browser menu; after that it opens from an icon, in its own window.
Does it work offline?
No. A connection is needed to save your writing and to use the AI. If your connection drops, watch the save status in the editor and make sure the chapter is saved before you close the tab.
Is it free?
Signing up and starting a novel is free. The free plan limits how many projects and chapters you can keep and how much AI you can use each month; the Pricing page has the current details for every plan.
What happens after I describe my novel?
Sign in and Muses opens a novel project for that book: a chapter open in the editor, empty story folders waiting for your notes, and an AI panel that already has what you just described, so you can carry straight on from there. You can rename or delete the project at any point.
Will the AI write the novel for me, or remember all of it?
It will not write the book for you. You decide what happens next. When the AI changes text you have already written, every edit arrives as a suggestion you accept or reject; when it drafts into a chapter that is still empty, the text goes straight into the editor for you to keep, rewrite or delete. It can look up earlier chapters and your notes before it drafts, but context limits still apply, so point it at the material that matters and check continuity yourself; consistency across a long novel is not guaranteed.
I already have a manuscript. Can I bring it in?
Yes. After you sign in, import it from the Muses home page: a ZIP or a whole folder of DOCX, TXT or Markdown files becomes the chapters of a project, and your folder structure is kept. You can import into a new project or into one you already have, then carry on writing and revising from there.
Who owns what I write, and can I get it out?
Your manuscript is yours, and nothing is locked in. Export a single chapter or the whole project as DOCX, Markdown, TXT or PDF at any point — you never have to finish the book to get your writing out.

Try it with the novel you are actually writing

An app is easy to judge once your own chapters are in it. Write a working title and one line about the story; you sign in on the next screen and what you wrote comes with you. Look around the project, then open it again tomorrow from wherever you happen to be.
