Novel planning software that's fun and effective.

What is Notebook.ai?

Notebook.ai is a digital replacement for the paper notebooks we've filled up over the years. Rather than jotting down paper notes about characters, locations, and things in your worlds, Notebook.ai helps you create detailed, dedicated pages for each of your ideas that can be revised over time, linked together, searched, organized, tagged, and more.

By going digital, your new notebook is able to take advantage of a ton of "features" you wouldn't get with plain paper.

It all starts with your first universe...

The Notebook.ai Multiverse

When you create a universe on Notebook.ai, you're creating a folder in which you can put your other notebook pages into.

Organizing your pages into universes automatically empowers your worldbuilding process with a few useful features:

check You can now focus on a single universe at a time. Doing this hides all of your notebook pages that aren't in that universe, so you can fully dive into the world you're working on.
check Whenever you link to other pages, you'll only see pages within the same universe recommended.
check You can now invite collaborators to work on pages in that universe with you. Of course, you don't have to! Everything on Notebook.ai is private by default.

Now it's time to start building your world!

The core worldbuilding blocks (Characters, Locations, and Items) are free to create for every account:

Characters

From your heroes to the little guys, each character plays an important role in your story.

FREE FOR ALL USERS

Locations

From magical mountains to urban modern settings, locations are the lifeblood of worldbuilding.

FREE FOR ALL USERS

Items

Books, weapons, artifacts, and other items: track who made them, who owns them, and more.

Materialize your world, bit by bit

Notebook.ai automatically generates questions about the pages you've created and politely asks for answers. When you answer any prompt, that answer is automatically saved to the relevant page.

You'll also notice other helpful features around the site that assist in the more mundane aspects of worldbuilding, freeing you up to do the fun work.

check If you customize a page's template, the fields you change are automatically synced across all of your pages of that type. For example, adding a field for an item's damage type will instantly create that field for all of your items!
check Whenever you mention another page, a two-way link is automatically created that you can click through, from either page.
check Whenever you link one page to another, you may notice the inverse link also created automatically. For example, creating a "subgroup" link on a Group page will automatically create a "supergroup" link back.

For more advanced worldbuilders, an optional Premium subscription unlocks 25 additional page types that help you give life to your world in incredible detail.

PREMIUM PAGE TYPES

Like the core pages, each premium page comes with a fully-customizable template, generative prompts, and an area to upload reference images and other art.

Finally... it's time to write!

Notebook.ai makes a fantastic reference for your favorite word processor, but you can also write in ours!

Reference your world's details as you write

Our integrated word processer lets you link your notebook pages directly to the documents they appear in. This lets you look up character or location information without ever leaving your editor!

If you prefer a more traditional word processor, Notebook.ai's search also makes it easy to surface the exact page you need, when you need it — and we look pretty good in a window next to Microsoft Word!

Browse every story your ideas appear in

Whenever you link a notebook page to a document in Notebook.ai, you'll also automatically start to see a "Documents" tab on that notebook page. In order words, a character's "Documents" tab will list all the stories they appear in; a location's "Documents" tab will list all the stories that happen there; and so on for every page.

Analyze your story with world-class AI

There's still plenty more to do after drafting your story! Writers with a Premium subscription can use our artificial intelligence to analyze their writing for style, structure, emotion, and readability issues.

Fixing these issues before taking your story to an editor frees them up to focus on the big picture and help you really make your story shine.

How long has this site been around? Notebook.ai launched in October of 2015, which means we've been around for about 10 years now!
Who owns the content I add here? You do. Notebook.ai is designed to feel like your own notebook. Every page you create is fully owned by you and private by default. You can also export your entire notebook in a variety of formats at any time.
What does it mean that the site is "open source"? This means that the source code required to run the site is freely available for anyone to access at any time. We also welcome contributions to that source code from developers who wish to add new features to the site.
What happens when I downgrade my account? When you downgrade your account, you'll be unable to create new Premium pages, but you will retain full access to view, edit, and share any existing pages you've already created, regardless of whether they're a Premium page or not.
Do you support PayPal? Yes, we do. You can prepay for subscriptions with PayPal, which act like traditional subscriptions except they automatically cancel at the end of their duration instead of renewing.

What are people saying?

Thank you for this amazing program. It's just what I, and hundreds of others, need to help flesh out their world and keep our ridiculous notes straight.

This is one of those products I didn't realize I desperately wanted till I interacted with it. It all works very slick, very modern.

JonBanes, Happy user

This is amazing. I have so many text documents sitting in various folders and files compiling all my info, so thank you so much for making a place I can keep everything online and in one place. This looks amazing and I'm so glad to see it grow and expand.

I just want to say I love you. I have spent the last week or so compiling notes from three different notebooks into this program, and it's been a few days and there's already tons of new things that are awesome.

Dr_Toast, Happy user

I want to say thanks! This is my first year doing NaNoWriMo, and I was kind of at a loss of where to start, but this website really helps get things in perspective. I can see that you really put a lot of thought into it. I hope to see it succeed!
