Riffable
Stories, riff by riff
Don't just read the story.Write what happens next.
Riffable is where readers become co-authors: start a scene, continue someone else's, branch the story, and help shape the path that becomes a book.
The machine that cannot lie
Leandro Resende Gomes · 2 people writing
The startup fired me for asking questions, but they let me keep the prototype — a writing assistant that can't generate fiction. Ask it for a story and it produces documented fact, every time, with sources. For fun, I typed: "Write a story about my neighbor." It wrote three paragraphs.

The Legendary Banana
a collaborative story · 12 riffs on this path · 4 co-authors
The monkey Juvêncio wished to find the Legendary Banana. The one you eat and never feel hungry again.
He looked for a map of the Forest inside the Nanny Fern. And he found a treasure map instead. Since he didn't want any treasure, he tossed the map aside.
Nearby, the owl Uja was sleeping upside down on a crooked branch. “Ask the River that laughs,” she murmured, sleepily — and was snoring again.
This is not a demo. It's a story being shaped by real readers and writers on Riffable.

The silence in this scene is deafening. I need to know who's at the door.

a living story by 4 authors
On Riffable, the first scene is not the finish line. It's an invitation.
For prompt lovers
Most writing prompts create one response, one scene, one version.
Riffable gives those ideas a place to keep growing: readers react, writers add riffs, paths branch, and the story becomes something people can build together.

Story direction
Cozy mystery · no gore · keep Vera's dry humor · end every riff on a hook.
- ◆Open a scene, a world, or a character for others to build on.
- ◆Set the direction so contributors understand the tone, genre, and limits.
- ◆Watch readers react, vote, and add riffs.
- ◆Choose what becomes part of the published version.
You keep the authorship. You gain unexpected directions.
For readers
Don't just follow the story. Step into it.
- ◆Continue a scene you care about.
- ◆Vote on the paths you want to see grow.
- ◆Create alternate turns without breaking the original.
- ◆Get credited when your riff becomes part of a published path.
Your reaction can become part of the story.
Whether you start the story or continue it, Riffable gives you a role in what it becomes.
Riffable lets authors guide the story before others continue it — with overall direction, chapter goals, and context that help every new riff stay connected.
NEW RIFF
◎Author's direction
◎ Author's direction×
◎ Chapter direction — Prologue⌃
riffs that follow the compass are more likely to become a page of the published book — with your name on it
- Before writing, contributors can open the author's direction.
- They see the overall story direction and the goal of the current chapter.
- Now the next riff has a purpose: preserve the tone, follow the chapter goal, and build on what already exists.
- Different voices. One story.
Riffable doesn't just open a blank page and say “continue this.” It gives every contributor a compass.
Create a world, a character, or both — then let other writers use them as the foundation for new stories, riffs, and branching paths.
- Start with a world.
- Define its premise, places, rules, conflicts, and atmosphere.
- Then create characters who can live inside it — or travel beyond it.
- Other writers can use them to start new stories, continue existing ones, or open new paths.
