STEP 01
Imagine the opening
Type a premise — "a lighthouse keeper finds a door in the sea." Spark, your playful creative companion, sketches the first scene in your voice and offers three ways it could go.
Every story you've ever loved made one choice. Manyfold lets you keep all of them — and hands the next decision to your reader.
Scrollytelling
Watch a single idea unfold.
Keep scrolling — each scene holds while the next slides in, the way a story reveals itself to a reader.
Scene 01
The opening
A lighthouse. A keeper. A door that shouldn't exist beneath the tide.
Scene 02
The discovery
Every reader begins here — then decides whether the door is mercy or trap.
Scene 03
The choice
Two paths split the night. Spark playfully sketches both; you decide where they lead.
Scene 04
The timelines
Each decision spins a new thread. Worlds drift apart, each carrying its own truth.
Scene 05
Infinite endings
Dozens of endings wait at the edges. Most readers will never find them all.
How it works
From a spark to a living story in four moves.
No node-graph PhD required. Spark helps with the first branches while Manyfold keeps the wiring visible, editable, and yours.
STEP 02
Branch the timeline
Accept a branch, rewrite it, or invent your own. Every choice forks the canvas into a new timeline. Spark keeps characters, tone, and continuity consistent across them all.
STEP 03
Shape the endings
Set conditions, hidden variables, and secret routes. Manyfold maps which choices lead where, flags dead ends, and helps you land every ending with weight.
STEP 04
Publish & watch them choose
Share to your followers in one tap. Readers swipe through choices while you watch a live heat-map of the paths they take — and the endings they never find.
Spark studio
Say the idea. Spark builds the world.
Plots, scenes, characters, endings — and the art to match. Your co-writer drafts every piece; you keep every decision.

The toolkit
Everything a branching story needs — and nothing it doesn't.
Spark, your playful creative companion
Describe a scene and Spark sketches it in your voice, suggests where the plot could fork, and keeps every character consistent across all your timelines. It plays alongside you, never instead of you.
The branching canvas
A living map of your story. Drag to fork a timeline, pinch to zoom across the whole multiverse, and see at a glance which paths connect — and which leave readers stranded.
Infinite endings
Set conditions and hidden variables so secret routes only unlock for the readers who earn them.
Remix & fork
Love someone's universe? Fork it, add a timeline, and credit flows back automatically. Stories grow together.
A social feed for fiction
Follow creators, react inside the story, and explore the next path everyone's talking about.
Live reader analytics
Watch a real-time heat-map of the choices your audience makes. See where they hesitate, which endings stay hidden, and where a branch loses them — then rewrite with the data in front of you.
Reads anywhere
A swipe-native reader on mobile, immersive on the web. Progress syncs across every device.
The canvas, live
This is what one story looks like.
Scroll, and watch a single opening fold into timelines, choices, and endings — exactly how it draws on your canvas.
One opening
The single scene every reader begins with — the lighthouse, the door, the first decision.
Choice points
Each node is a fork. Spark suggests options; you decide which survive and where they lead.
Diverging timelines
Branches carry their own state — a character lost in one path is gone for good in that timeline.
Many endings
Hopeful, tragic, secret. Every leaf is an ending a reader can reach — and rush back to change.

For readers
Reading becomes a choice you make.
No menus, no manuals. Readers swipe through your scene and tap the path that pulls them. Choices are weighted live, so they feel the pulse of every other reader who came before — and the quiet thrill of being the few who found the hidden ending.
- ◆ Swipe-native, one-handed reading
- ◆ See how the crowd chose — or hide it for a blind run
- ◆ Rewind any choice to chase a different ending
The Keeper & the Tide
by @marlowe · timeline 3 of ∞
The door beneath the waves hums when you touch it. Salt water pools at your boots. Somewhere behind it, a voice that sounds like your mother says your name.

Backdrops painted by Spark
The lamp had burned for two hundred years — and tonight, something answered it from below.
Beneath the tide the door hums like a struck bell, warm where the ocean should be cold.
It opens onto a sky that has never heard of her stars — and a shore where someone is waiting.

"I drafted a 14-ending mystery in a weekend. My readers spent a month arguing about which path was 'canon'. Nothing else lets me build like this."

"Spark suggests forks I'd never have written, then gets out of my way. It feels like a playful creative companion, not a tool trying to become the author."
