Create rich worlds with your free worldbuilding notebook
Track multiple stories at once by organizing your ideas into just the universe they belong in.
From your heroes to the little guys, each character plays an important role in your story.
From magical mountains to urban modern settings, locations are the lifeblood of worldbuilding.
Get to know your characters. Track every detail of their thoughts, appearance, family, and personality.
Immerse yourself in vibrant worlds with specialized notebook pages for your countries, cities, landmarks, and more.
Focus on one universe at a time and automatically filter everything else out. Reorganize, sort, and write freely.
Invite anyone to review any pages you decide to share. Sometimes a second set of eyes makes all the difference.
Backed up forever
Never lose a notebook full of priceless ideas again. Notebook.ai backs up and protects your work.
No ads, ever
Rest easy knowing your notebook is safe and completely private by default, but shareable if you choose.
Write smarter with integrated novel-writing software
Notebook.ai helps flesh out your ideas by asking you questions about the pages you create.
When every little fact is stored in one place, you can rest easy knowing you won't accidentally contradict yourself.
Quickly find anything, anywhere — even that random thought you jotted down at 3am two years ago.
Use the built-in document editor to reference any aspect of any page in your notebook without losing your momentum.
Analyze your writing with a world-class artificial intelligence that measures readability, style, emotion, and more.
Grows with you
Plan as much as you want in your notebook — for life. The only limits here are your imagination.
Go the extra mile with premium notebook pages
Notebook.ai's free tier was intentionally designed to be enough for most worlds, but if you want to support the site and take your worldbuilding to a new level, a premium subscription is available that unlocks 25 additional page templates to use. Each template is customizable and comes with its own set of writing prompts.
Your personal bestiary includes the wildlife, critters, merfolk, and other interesting beings of your world.
Celestial bodies orbiting through space, carrying a planet's-worth of worldbuilding opportunities.
Underneath our feet, continents form the base and borders our worlds are built upon.
Kingdoms, countries, regions: you decide what international borders look like in your story.
From the smallest statue to the biggest mountain, landmarks can play important roles, too.
Towns can both unite and divide your characters. Keep track of what makes your towns unique.
Fill your towns with stores, offices, historical buildings, and residences for your characters.
From Hogwarts to Walkerville to Brakebills, schools educate every new generation in our worlds.
Jobs build words. How do your characters make a living? What skills are the most in-demand?
Create your gadgets, gizmos, and all kinds of advanced (or primitive) technologies.
Vehicles come in many shapes and sizes: cars, boats, spaceships — or something completely new.
Conditions affect your characters for better or for worse. Create diseases, blessings, and more.
Humans can be joined by elves, orcs, werewolves, vampires, dragons, and many other races.
Gods, goddesses, and other godly beings in your world — every world came from somewhere.
Organizing your world's beliefs into cohesive religions can lead to a more epic world for your readers.
A source of magic often creates a multitude of spells, potions, and occasional trinkets.
Bundle your characters, locations, items, and other ideas into any kind of collection you need.
Language is a bond that weaves a culture together. Are there any new languages in your world?
Everyone has something they celebrate. Honor your characters by detailing their traditions.
People are naturally competitive, and sports seem to naturally emerge in almost every world.
Scenes are events that happen in your world, ranging in size from a nice breakfast to entire wars.
Plot your plot over time. Track what happens every step of the way.
Collect and organize notebook pages into customizable collections you can share or collaborate in.
