Branching picture books for ages 4–9 · designed for co-reading
Tonight, your child leads. Each choice changes what happens next, and over time those choices show you a side of your kid you might not have noticed.
60+ stories retold from classics families already know

What would your child do?
A real fork from “Tap-Tap, Swish-Swish—Three Houses!” — one of the five free books. Choose Mina's path.

Everyone meets in the yard again. All three houses are still standing strong. They spot a few places to fix and smile together.
On this cold, windy night, how will everyone stay cozy?
Choices are not decorative. They change the next scene and can lead to a different ending. A reread opens paths the child has not tried.
There's no questionnaire. Your child just reads, and after three books you get a first-impression card built from the paths they chose.
Familiar classics and original worlds, rewritten for young readers. No preaching — the consequences do the talking.
Recommendations respond to stories and choices already explored, while custom stories can fill a theme the family wants next.
Reading together can reveal something worth asking about
The child simply enjoys the story. Over time, choices appear across five broad dispositions, and you can set them next to your own impressions to see where they match — and where they don't.
Research-informed observation axes · no grade, diagnosis, or better side
An example comparing story-choice observations and a parent's prior impression across five axes.
Example view — the same visual language used in the parent report
How a choice becomes an observation
The actual path a child chose remains connected to a disposition or value tag.
Add a name, age, and a few interests—no photo required.
The parent picks a book and the child chooses each path.
Use completed stories to guide a recommendation or custom request.
After three books, get a first read on the patterns.
New stories add new observations. Nothing about the picture is permanent.
The opening of “The Tortoise and the Hare” keeps the same event and choices while sentence length, rhythm, and detail change by age band.
Ages 4–5
Thump-thump! The starting bell shines. Haru's toes wiggle, wiggle.
Ages 6–7
Race day came to Sparkle Forest. The starting bell waited at the line. Haru's toes wiggled with excitement.
Ages 8–9
The long-awaited race day finally brightened Sparkle Forest. Beneath the morning sun, the starting bell gleamed while Haru's excited toes kept wiggling inside their shoes.
Short and rhythmic for a four-year-old; richer and more layered for a nine-year-old.
101+ stories · 364 choices · 8+ worlds






The same friends keep showing up across books. A few stories in, your child will greet them by name.

A squirrel who is often the first new friend at the forest entrance

A little jellyfish who stays close when the lantern light grows faint

A tin robot whose spring trembles whenever a friend feels nervous

A soft snow rabbit who warms a friend's frozen hands

A person reviews every plot and every fork. Your child's name and reading level are layered on top.



One of a kind
This isn't a name swapped into a template. We build a new story from your child's name, looks, and current obsessions — and it branches too, so their choices still shape how it ends.

Yes. Tell us the name, how your child looks, and what they love, and we write a story just for them and deliver it to your shelf the next day. After a few books it also reflects the paths your child chose.
Each story runs about five minutes, and because your child chooses at every fork, the same book ends differently night after night. The same shelf works on the web and inside the Toss app, and parents receive the choices as an observation record.
One story at a time, with your child choosing the path. Five free stories plus one paid story unlocked free every week covers a holiday trip. We never collect photos, voice, or location.

A question for tonight
What was the most surprising idea you had today?
Values encountered inside the story
We keep the paths where sharing, promises, teamwork, or courage came up. They're conversation starters, not a grade.
The full report walks through all five dispositions and the value moments the same way.
