Search your creatures


If you've got a lot of creatures, 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 creature.

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

Private by default


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

Free page


Free users can create an unlimited number of creatures 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.

 

pets Get a head start with a rich creature 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 creature. 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 creature page.

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

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

Creature features

photo_library Upload images to your creature


Creatures 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 creatures 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 creatures!

vpn_lock Focus on creatures 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 creatures 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 creatures 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.

pets Build your creature piece by piece with personalized writing prompts


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

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