Creating Planets on Notebook.ai

Celestial bodies orbiting through space, carrying a planet's-worth of worldbuilding opportunities.

Creating planets on Notebook.ai is easy.

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

searchable Search your planets

If you've got a lot of planets, 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 planet.

You can also filter your planets by tag, whether you've favorited that page, and which universe it's in.

lock Private by default

Your ideas are valuable. Every planet 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 planet page you want, however you want, whenever you want.

star Premium page

Planet notebook pages require an active Premium subscription to create, but users on free plans can view and edit their existing planet pages at any time.

Notebook.ai is your personal worldbuilding notebook; any page you create is yours forever and you'll never lose access to any part of it for any reason — even if you downgrade to a free account in the future.

Get a head start with a rich planet 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 planet. 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 planet page.

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

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

Planets 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 planet 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 planets!

vpn_lock Focus on planets 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 planets 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 planets 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!

brightness_4 Work in light or dark mode

Protect your eyes at night by choosing between light and dark themes at the click of a button, available across the entire website.

public Build your planet piece by piece with personalized writing prompts

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

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