Mundaria
01
Everything is connected, without wiring it
Mention a page while you write and the link exists in both directions. Every page shows who mentions it. The graph shows the whole world at once, and it stays readable at a thousand pages.
For game masters and worldbuilders
Your world stops living in twelve documents
Mundaria turns scattered notes into a world you can walk through: linked pages, maps with pins, secrets your table cannot see, and everything findable in one keystroke.
Free during the beta. No card, no payment method exists yet.
Every campaign starts as notes. Mundaria turns them into a place you can walk through, show your table and take with you — pages that know each other, maps that answer, and secrets that stay secret until you say so.

What it does
One world, every way you need to see it
02
Maps that answer questions
Pins that open pages, regions and routes you draw, layers you turn on and off — and a ruler that tells you how far it is and how many days the trip takes, in your world’s own units.

03
Secrets that stay secret
Any block can be DM-only. Your players see the same page without them, and you reveal a block when the table earns it. There is a "view as player" mode so you can check before you share, and it works on every screen.
Page · People of the Mouths
Ilda Verano
Mistress of the Tide Guild for fourteen years. Seventy-one, blind in her left eye, and she still reckons faster by hand than two apprentices with an abacus.
Only visible to the DM
Ilda already knows that last moon’s table was wrong. What she has not yet worked out is that the error is in the copying onto paper — and that it was done on purpose.
“Water does not bargain.” — Ilda Verano
04
The session, not just the world
Sessions have a date, an index and their own people and places. Table mode strips the chrome for the screen everyone looks at, and afterwards a single link shares the recap.
05
An assistant that read your world
The Scribe answers from your pages, tells you when something is not written yet, and can turn its answer into a page. Nothing it writes reaches your world unless you put it there: you keep editorial control.
Who signs the tide table, and is she hiding anything?
The Scribe
Ilda Verano, Mistress of the Tide Guild, signs the whole table. Your notes say she already knows last moon’s table was wrong, but not yet that the mistake was made on purpose.
Ilda Verano The Tide Guild
Not written yet: who copied the table onto paper.

Sheets that keep score
Meters, fields, properties with mentions and an infobox inside the page.
Anything, in one keystroke
Ctrl K jumps to any page, tag or map while you are mid-sentence at the table.
A link for your players
Share the world or a session recap. They see what you revealed and nothing else, without making an account.
Built for the game master who prepares
What it is
A persistent workspace for one world. Not a wiki you have to wire up, not a folder of documents, not a notes app you bent into shape. Pages, maps, sheets, sessions, search and an assistant, all reading the same world.
Who it is for
The game master who prepares. If you have run a campaign for more than three sessions, you already have the problem this solves: you know the answer is written down somewhere, and finding it takes longer than making one up.
And what it is not
Mundaria prepares and presents. It does not run the mechanics or hold the state of a game in progress: no initiative tracker, no tokens, no fog of war. If you use a virtual tabletop, this sits beside it — it does not replace it.
What game masters say
What it costs
During the beta there is nothing to pay. These are the prices for when billing opens, and the free plan stays free.
Free
US$ 0
Two worlds, 200 MB of images and 50 Scribe questions a month. Everything else is the same product: maps, secrets, sessions, the graph and the export.
Complete
US$ 9 a month
Unlimited worlds, 5 GB of images and 400 Scribe questions a month. US$ 81 a year, which is three months free.
Only the game master pays. Your players never do, and they never will.
FAQ
Questions before you start
The short answers. The long ones are in the terms, the privacy policy and the AI policy.
Is it free?
During the beta, yes, entirely: there is no payment method in the app yet. When billing opens, the Free plan stays free — two worlds, 200 MB of images and 50 Scribe questions a month — and Complete costs US$ 9 a month or US$ 81 a year.
Do my players need to pay or sign up?
No. Only the game master pays, and players never will. To show them the world or a session recap you send a link, and it opens without an account.
Can my players see my secrets?
No. Blocks marked DM-only are removed on the server before anything reaches your players, so they are not hidden — they are simply not there. "View as player" shows you exactly what they will see.
Does it replace my virtual tabletop?
No, and it does not try to. Mundaria is where you prepare and present the world; it has no tokens, initiative or fog of war. It sits beside Foundry, Roll20 or a table with paper and dice.
Which game systems does it work with?
Any. Nothing in Mundaria is tied to a system: sheets are fields, meters and properties you define, and the dice roll whatever you write, like 2d6+3.
Can I bring the notes I already have?
Yes. You can import an Obsidian vault and keep its folders, tags and links, or restore a world from a Mundaria backup.
What happens to my worlds if I stop paying?
Nothing is deleted. If you have more active worlds than the free plan allows, the extra ones become read-only: you can still browse and export them whole. Exporting has no limit, and never will.
Does the AI learn from my world?
Your worlds are never used to train AI models. The Scribe reads your pages to answer you, says when something is not written yet, and nothing it writes reaches your world unless you put it there.
Where can I use it?
In the browser, on a computer, a tablet or a phone — there is nothing to install. The app is in Spanish and English.
The boring promises, in writing
- Your worlds are never used to train AI models.
- No analytics, no third-party cookies, no ad trackers.
- If Mundaria ever stops serving you, your worlds leave with you.
