Storybun is a collaborative writing space for humans, not models. Create a story with its synopsis, genres, and boundaries, then invite others to add chapters inside the world you defined. Slow, thoughtful, one chapter at a time.
“Storybun feels less like an app and more like a room where our ideas can bump into each other.”
Every autumn, the river lights up with floating lanterns. Each one belongs to a story that hasn't found its ending yet.
The internet is full of things that will write for you. Storybun is deliberately slower. It gives you boundaries, other humans, and just enough structure to make finishing a chapter feel possible again.
No auto-generated chapters, no “fix my prose” button. Just you, your ideas, and the satisfaction of seeing a story change because you touched it.
Invite people you trust or open the doors. Collaborators add chapters within the boundaries you set, taking the story to places you wouldn’t reach alone.
Cooldowns, chapter limits, and review options keep the story moving without turning it into a firehose. Enough rules to feel safe, not boxed in.
Storybun is built for slow-burning, asynchronous collaboration. People drop by when they have something to add: a chapter, a twist, a quiet scene from another point of view.
One notebook, many hands. Each chapter comes from a different perspective inside the same world.
Chapter 4 · Lina
Writes from the lanterns' perspective, listening to all the wishes at once.
Chapter 5 · Arun
Follows the kids daring each other along the river path.
Chapter 6 · You
A quiet scene from the river itself, watching everyone above the surface.
Every story starts as a little world you define: a synopsis, some genres, a few rules about how fast it moves and who gets to touch it. Then other people add chapters inside that world.
The world in one paragraph
“In the town of Hinterglow, everyone owns exactly one lantern. When it goes out, it means the story they are living has reached a turning point.”
Storybun doesn't care if you update every day or once a month. It's built to fit around the rest of your life, not compete with it.
You and a few friends dropping chapters whenever life allows.
Campaign logs, shared universes, long-running comforts.
Stories that begin and end in a handful of chapters.
Writing nights, weekend projects, low-stakes chaos.
Private stories you'll invite others into later.
Journals, test runs, worlds you're not ready to show yet.
