The atlas and the manuscript, on one desk
Build the world.
Then write the book inside it.
Your characters, maps, history and chapters live side by side, so the world you invented on page 12 is still true on page 400.
AI is optional. It shows what it costs, and nothing it suggests goes into your world until you accept it.

What's on the desk
Everything a long book leans on, where you can reach it
Writers keep their world in six places: a notes app, a spreadsheet, a folder of maps, a timeline on the wall, the draft, and their memory. This is one place.
A desk made for long books
Chapters in parts, scenes with their own point of view and setting, daily goals and a streak. Earlier versions of each chapter are kept, so you can go back.
A codex that asks what an editor would
Profiles shaped to each kind of entry. For a character: want, need, wound, the lie they believe, how they talk. For a faction: its seat, its methods, its secrets.
History that keeps count
Eras and events in your own calendar. Give someone a birth year and the app knows their age in every chapter.
Maps worth printing as endpapers
Coastlines, ranges and rivers drawn from your codex, from one valley up to a whole planet, a star system or a galaxy. Any place can hold a map of its own.
Continuity while you write
Timeline slips, the dead still acting, two names that read alike on the page. The structural checks cost nothing and run as you go.
Ready for the printer
Print-ready Word at your trim size, standard manuscript format for agents and EPUB. On paid plans, Covers builds a full cover wrap with the spine measured from your page count.
For readers
Read a novel with its world beside you
Reader mode builds a companion for an EPUB you are reading. The app reads it one chapter at a time and builds the cast, the places, a map and a timeline, each held back until you reach the page that reveals it.
It knows where you are
Set your chapter or page, or just scroll. Every person, place and event after that point stays hidden, down to the paragraph.
Tap a name to remember who that was
Characters you have already met are underlined in the text. One tap shows what the book has told you about them so far.
The map fills in as you travel
Places appear on the map when the story reaches them, and the timeline and the connections between characters grow with each chapter.
Your book stays yours
The EPUB file is never uploaded. Each chapter goes to the AI once to be read, and only the notes about its world, the chapter titles, the cover picture and your reading place are saved, privately.
- Works with DRM-free EPUBs, such as Standard Ebooks and many indie and small-press titles. Books bought through Kindle, Kobo or Apple Books are usually locked. Building a companion uses one AI credit per chapter, plus one for its maps.
Inside every world
A world, page by page
Each world you start gets these pages, and they all read from the same codex. Change a name, a date or a coastline once and every page sees it.
- Writing desk
- Chapters, parts and scenes, with tracked changes, comments and the codex beside the page.
- Codex
- Every character, place, faction, ship and belief, with profiles, canon facts and a picture.
- World graph
- Every entry and connection drawn as one web, so you see who serves whom.
- Map
- Coastlines, ranges and rivers drawn from your codex, with a map of its own for any place.
- Chronicle
- Eras and events in your own calendar, with births, deaths and ages worked out.
- Plot & timeline
- Plot threads and their events, in the order the reader meets them.
- Continuity
- Checks for timeline slips, the dead still acting and names that read alike.
- Covers and the world bible
- A cover wrap sized to your book on paid plans, and a formatted bible of the whole world.
Already writing somewhere else? Bring in a Word file (.docx), Markdown, plain text or text pasted from Google Docs, and its chapters come across for you to check before anything is saved.
How it works
From a blank page to a printed book
- i.
Start small
Answer a few questions and get a starter world with gaps left for you, begin with nothing but a title, or bring in a manuscript you have already started.
- ii.
Write
Open the desk. Name a character, and their facts and age appear beside the page.
- iii.
Grow the world as the book asks
Add places and watch the map redraw. Date the history. Connect who serves whom and who betrayed whom.
- iv.
Finish
Check continuity, then export the manuscript, the world bible and the cover wrap.
AI when you ask for it
Every AI action shows its cost before it runs. Suggestions arrive as a list you tick through, and the voice notes in your World settings apply to every draft. Typing it yourself is always free.
Your work leaves with you
Export any time: Word, EPUB, Markdown, a formatted world bible, and a world file for a backup or a co-author. The world file is the complete copy; the Markdown export holds the text and the codex.

Pricing
The atlas, the desk and the AI, with nothing extra to set up
Every plan has the whole writing desk, the codex, maps, history and exports. Paid plans add Covers and share links. AI is built in, so there are no keys to set up and no second bill from a model company. Plans differ in how many worlds you can build, whether Covers and share links are included, and how many AI credits you get each month.
Early access: billing has not opened yet, and every account has the Writer plan free until it does, whichever card you start from. We will email you at least 30 days before billing opens, and nothing is charged without your agreement.

Prices in US dollars. Most AI actions cost one credit: developing an entry, an answer from the Loremaster, a continuity check by the AI, one chapter read in reader mode. A picture costs three. A starter world, a generated history and each part of notes read into the codex cost two; bringing in a manuscript is free. A book's maps in reader mode cost one more. Every action shows its cost before it runs, and asking for exactly the same thing again is free unless you choose to run it fresh. Credits refill at the start of each month (UTC) and do not carry over.
