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.

Universes are free to create

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 creators, with Premium pages serving as a way for more advanced worldbuilders to further flesh out their rich worlds in even more detail.

You can fill out as little or as much as you'd like on every new universe.
