Writing a book is hard.
Your tools shouldn't make it harder.

New — Function-calling AI

An assistant that actually knows your book

Not a generic chatbot. Writer Atlas ships a purpose-built assistant that can read your outline, look inside chapters, follow characters across pages, and even draft new pages for you — all inside the same tab.

Reads your book on demand

Grabs the outline, a specific chapter, the current page or the full book only when needed — no wasteful token dumps.

Searches text and characters

Free-text search across every page, plus dedicated tools to trace where each character appears in the manuscript.

Creates new chapters and pages

Ask for “three scenes for Chapter 4” — the AI adds them to the Draft tree instantly, prefixed with AI: so you can review or remove.

Learns your writing style

Feed the assistant a paragraph describing your voice; it keeps that style in mind for every rewrite, suggestion, and new page.

Book, chapter or page focus

One click to scope the chat to the whole book, a single chapter, or just the page in front of you. Multiple chats per page supported.

Free by default, or bring your own key

Ships free on a managed model. Plug in your own OpenRouter key any time to unlock premium models with full pricing control.

Connect Writer Atlas to an AI assistant like Claude and work on your books by chatting — outline, draft, and edit chapters without ever leaving your AI app.

Write by chatting

Ask your AI to open a book, read a chapter, or add a new page — it works directly on your manuscript.

You stay in control

Grant access to one book or all of them, read-only or full edit, with an optional expiry — and revoke it anytime.

Works with your tools

Connect popular AI clients like Claude, Cursor, and VS Code using the open MCP standard.

Frequently Asked Questions

What is Writer Atlas, and who is it for?

It is a workspace for long work: you build your book as a tree of folders and pages instead of one endless file, so you can move a chapter, split a scene, or read the whole structure at a glance. It is not built for novels alone — you choose the kind of work you are writing, from a novel, a non-fiction book, a research project, a textbook, a collection of articles, a screenplay, or a memoir, and the platform follows that choice.

Is there a free plan, and what does it include?

Yes, and it does not expire. The free plan gives you three books, up to a hundred pages in each, the whole editor, the free AI models, and export to HTML, Markdown and plain text. Paid plans remove the book and page limits, add a monthly allowance on the paid AI models, keep more of each page's history, and unlock the publishing formats. Prices are adjusted to the purchasing power of your country, so what you see is what applies where you live.

Who owns what I write, and do you train AI on my book?

Your text is yours. We do not train any model on your book, we do not sell it, and we do not show it to anyone. What the assistant reads is sent to the model only to answer the request you made, and only the part of the book you pointed it at. Your export is always available, so nothing you write is locked inside the platform.

Will the AI write the book for me?

No, and it is not meant to. The assistant sits beside the editor and reads what you point it at — the whole book, one chapter, or the page you are on — so its answer is about your text rather than a generic one. It can summarise, question a plot, suggest a direction, or write a passage when you ask it to; and every line it writes is marked as its own, with the previous version of the page kept, so you can always tell your writing from its suggestion and go back.

Can I choose the AI model, or use my own key?

Yes to both. You pick the model, the temperature, the writing style and the standing instructions for each book separately, because a research project is not addressed the way a novel is. And if you already have an OpenRouter key, you can plug it in and use any model it reaches, billed by them and not counted against any allowance here.

Where can I write, and does it work offline?

In any browser, in the desktop app for macOS, Windows and Linux, and on Android — an iPhone app is on the way. The desktop app keeps your books on the device, so you can read and write with no connection at all; what you wrote waits in a queue and goes up the moment you are back online.

Can I bring in a book I have already written?

Yes. You can import Word files (.docx and .doc), RTF, Markdown, HTML and plain text, up to 50MB each, and the headings, formatting and embedded images come over with the text. A PDF or an EPUB is not turned into editable text; those you attach in the research folder as a reference beside the book.

Which formats can I export to?

Ten, and the whole book comes out in its right order with its images. HTML, Markdown and plain text are open to everyone; Word, PDF and EPUB come with a paid plan; and RTF, ODT, LaTeX and Final Draft (FDX) come with the top plan. Right-to-left text is shaped and joined properly in the PDF, which is the file most people hand to a printer.

Can I get back an earlier draft of a page?

Yes. Every page keeps a history you can read and restore, and a snapshot is taken before the assistant writes into it, so an AI edit is never a one-way door. The free plan reaches the five most recent versions of a page and the paid plans reach all of them; and if you move to a cheaper plan nothing already saved is deleted — you simply reach less of it.

Which languages can I write in, and is right-to-left supported?

Write in any language you like — the editor, the book tree and the exported files all follow the direction of your own text. Right-to-left was the starting point rather than something adapted later, and the interface itself comes in twenty languages, eight of which run right to left.

Can I connect Claude, Cursor or another AI tool to my book?

Yes, on the top plan. Writer Atlas runs an MCP server, so any tool that speaks MCP — Claude, Cursor, VS Code and others — can read your book and write into it from where you already work. You issue the token yourself, you decide whether it may write or only read, and you revoke it whenever you want.

What happens if I cancel or move to a cheaper plan?

You cancel yourself, in one click, and you keep the paid plan until the period you already paid for ends. Nothing you wrote is deleted or locked: every book and every page stays readable and editable, the limits only apply to creating something new, and your export stays open so you can take the whole book with you.
