Creating Universes on Notebook.ai

Track multiple stories at once by organizing your ideas into just the universe they belong in.

Creating universes on Notebook.ai is easy.

To get started, just click Universes under the "Worldbuilding" header in the site sidebar. You'll be able to see or edit all of your existing universe pages and create new ones at any time.

Search your universes


If you've got a lot of universes, you can quickly get around to the right one with Notebook.ai's full-text search. It searches your entire notebook for anything you wrote about that universe.

You can also filter your universes by tag or whether you've favorited that page.

Private by default


Your ideas are valuable. Every universe you create in Notebook.ai is owned by you, completely private by default, and only accessible to you.

But of course, you also have full control over that privacy and can share any universe page you want, however you want, whenever you want.

Free page


Free users can create up to five universes on Notebook.ai.

Notebook.ai's free tier was designed to be more than enough for most people, with Premium pages serving as a way for more advanced worldbuilders to flesh out their world in more detail.

 

language Get a head start with a rich universe template


Templates on Notebook.ai are what help our unique worldbuilding system better understand your world.

You can fill out as little or as much as you'd like on every new universe. You'll see progress indicators every time you edit it to show where you can make progress on, and our system will intelligently generate questions for you around the site that will automatically save your answers to the proper place on your universe page.

Templates are also fully customizable across every universe in your notebook.

You can browse the default template for universes here; click any category to see its questions.

Universe features

photo_library Upload images to your universe


Universes and other worldbuilding pages all come with a dedicated area to upload and showcase your own uploaded images.

All users start out with 50MB of image storage space available for their notebook (usually around 250-500 images), but Premium users receive an extra 10GB (10,000MB) of storage space for plenty of wiggle room when decking your universes out with all kinds of images.

The images you upload replace any default images the site uses, which makes your notebook truly feel yours when you see all of your fancy universes!

vpn_lock Focus on universes from a single universe


Building entire fictional worlds is hard, and it gets even harder when you've got ideas spanning multiple universes or worlds.

Focusing on a single universe at a time is a good example of how Notebook.ai tries to stay out of your way as a worldbuilding tool, while also presenting your ideas front-and-center for you to work on without distractions.

After you've created a couple universes, you can select any one at any time to filter your entire notebook to just universes and other pages that exist within that universe, letting you focus on just what's important right then.

group_add Invite others to collaborate


Notebook.ai lets you add an unlimited number of collaborators to your universes. Each one has full access to work alongside you on your universes and other pages within that universe.

If you have a Premium subscription active, your collaborators can also share all of your Premium perks while working in your universe, too!

language Build your universe piece by piece with personalized writing prompts


Once you've started creating a universe or two, you'll start noticing our worldbuilding tool asking you personalized questions about those universes around the site.

Whenever you write an answer to any of these prompts, they'll automatically be saved to the relevant field on your universe notebook page and you won't be asked the same question again.
