Avoid costly changes later by detailing your world now.

What is

Most creatives have at least one old notebook lying around somewhere, full of old plots, interesting characters, monsters, enchanting locations, or a myriad of other margin-scribbled thoughts. Others have piles of old "plot idea" or "world idea" documents in their favorite cloud storage. Others still have their brilliant, rich worlds fermenting in their heads. is a worldbuilding tool that organizes, saves, and helps in fully fleshing out your fictional worlds, your way.

Your digital notebook takes full advantage of being just that — digital. Instead of fitting notes in the margins of pages past, you'll always have space to expand every idea. Instead of reading backward in your notes to remember who gives your character a legendary sword, every little detail about them is organized and just a click away. You don't need to flip around the pages in your old notebook to jump from a character to their birthplace to other characters born there; every "link" between your ideas is a real link, and lets you click to jump from one to the next.

How do I use it?

It's actually really easy. Just sign up and create something — anything — and you're doing it right.

Most users start by creating a universe to hold everything they create afterwards. You can call it your game's title, "My Universe", or whatever you want. You'll be prompted to enter a description and a few other questions, but everything's entirely optional.

Once you have a universe, try creating a character or two for your main characters. You'll notice the process of creating a notebook page is exactly the same regardless of what type of page you're creating. You click create, you're presented with a bunch of optional fields to fill out about it, and you're done. You can create a location for where your game starts, and items for any relevant objects or trinkets throughout your plot.

Once you've got the basics, just expand outward for your game world! Right now, there are nine different page types you can create in

Separate your worlds with Universes

In addition to the page types detailed above, you can also create Universes.

You can think of a universe as a bucket of time or space: a literal universe, a world, a country, a time period, even just the park down the street — your universe contains everything related to the game you're building, and lets you focus entirely on just what's relevant right now, even when you create multiple games in

When you create a character, a location, or anything else within, you'll be asked what universe it belongs to. When you visit that universe's page in your notebook later, you'll see everything inside it from one convenient place.

Tip: Once you've created a universe on, you'll see a new dropdown in the top-left corner of every page. Selecting a universe from it will "lock" your notebook to that universe: you'll only see content from that universe, and anything new you create will automatically be added to it. You can unlock or switch universes at any time.

Share your game with your team with easy privacy rules

By default, every notebook page you create is private, for your eyes only, and completely owned by you.

However, if you're sharing a game in progress with your team, you may want to give them full access to the world. We offer two different ways to share pages with teams that should make it easy to use together.

Every page has a "share" button that, when clicked, gives you the option to toggle privacy for that page or the privacy of the universe it belongs to. You're given the URL to that page to share, and others can see what you see (but not edit, yet) by visiting the shareable URL. As long as either the page they're visiting or the universe it belongs to is public, they'll be able to see the page.

If you prefer, you can also share your entire universe at once and manage the visibility of every page within a universe with a single switch by simply sharing the universe itself, instead of each individual page. Of course, this switch goes both ways: you can toggle the universe back to private at any time.

If you decide to make a page or universe private later, you can simply toggle the same switch and your pages become immediately inaccessible to anyone other than yourself — even if they still have the URL.

Tip: We'll be adding team-based collaboration to in the future so multiple people can work within the same universe, transforming it into a powerful collaboration hub for your entire team to build a world together.

Keep your world focused with consistent details

Having an in-depth reference while developing your game lets you quickly look up even the smallest of details when you need them and keep working uninterrupted. You'll never again have to flip backward to find out what quest rewards should be, or exactly how much a mega-hyper-potion heals. Everything you need is organized and at your fingertips.

If you're not the type to build your world out completely before development, can also be used as you go for the same kind of references. Each time you introduce a new character, simply create a character page for them (it's fast!). When you describe anything about them, you can jot it down in its rightful place and anyone on your team can then refer back to it later.

And, of course, if the default fields don't cover every little detail of your world, you can always create new categories and fields on any content type, like "biggest weakness" on characters or "hidden treasures" for locations. It's your world — track anything you want!

Tip: When you create a custom field for any page type, it's immediately available for all other pages of the same time. For example, creating a "dialogue style" field on Characters will add the field to all characters — both existing and not yet created.

Upload images for inspiration or reference

Whether you're in the initial idea stage or further along and looking to save reference material, allows image uploads to any notebook pages you create.

You'll notice that any images you upload are featured across the site, from your dashboard to individual notebook pages. In addition to a Gallery tab on content that shows off every image uploaded to it, you'll also see slideshows banners at the top of your notebook pages highlighting the images you upload — and you may even see a character peeking back at you from your dashboard from time to time!

Free users start with 50MB of storage space that can be used to upload any size of image. Premium users are boosted an additional 10GB of storage space. You can delete any image at any time to reclaim and reuse its space.

Tip: Uploading images is a great way to save the maps of your world. They're highlighted at the top of their Location page, and you can click to expand them to their full, original size at any time.

Export your entire notebook in more and more formats

We want to make sure you know you own your ideas, so we provide multiple formats for you to export your entire notebook — or individual page types like characters or locations — any time.

Right now, you can export content from the "Notebook Downloads" link in the top-right after signing up. We support exporting in CSV, JSON, XML, and a text-based "outline" format that's great for printing out and marking all over. Exporting is free, always available, and immediate.

Tip: If your team needs to export in a new format we don't support (yet), you can create an issue on our feature tracker requesting the format you'd like and we'll see how quickly we can add it in.

How much does it cost?

Creating core notebook pages (universes, characters, locations, and items) is free and doesn't require any payment information to start creating your novel's world immediately upon signup. Free users, however, are restricted to five universes to get started with.

We believe this trifecta of people, places, and things covers most worlds, but serious worldbuilders often opt to pay for a Premium membership, which unlocks six additional ways to worldbuild — namely creatures, races, religions, groups, magic, and languages.

Premium memberships are $9.00, billed monthly, and allow you to create unlimited amounts of any type of content. Additionally, a Premium subscription also increases your image upload storage from 50MB to 10GB.

How does it compare to other worldbuilding software?

We launched last October and we've been iterating fast based on the feedback of thousands of users excited to have a smart tool for their worldbuilding. While we focused primarily on authors to begin with, many users have told us we're a fantastic solution for creating the rich worlds necessary for high-quality game development.

While game development has been traditionally carried out in an unstructured wiki-like environment (or via pen and paper), we've compiled a feature comparison table against other popular worldbuilding software used in the industry. Free Aeon Timeline 2 Nevigo articy:draft Premium

Who owns the ideas I store in

You do, 100%. We've written more about this in our privacy policy.

Additionally, all content is private by default and only accessible by you. When you click the "share" link on any content, you're given the option to mark either that individual page or the universe it lives in as "public" or "private". A public universe allows viewers to click around and see every page in that universe, while a public page in a private universe allows only that page to be viewed. You can mark anything private again at any time and it will be instantly applied.
