Pose tracking runs on the device

One static book in.
Everything a kid can play, watch, and move through, out.

ActivePlay is an activity layer for children's content. A finished picture book goes into Studio and comes back out as an interactive story that won't turn the page until your child moves, a narrated animated short with movement cues on the beat, and the activity layer underneath both. Pose tracking runs on the device. Nothing uploads.

Input

A finished picture book.

34 pages. A PDF. Nothing to do but turn them.

ActivePlay Studio

Interactive story

The page won't turn until the reps are done. 6 gates, ~40 reps, 15 minutes.

Move-along video

The same story animated and narrated straight through, cues on the beat.

Activity layer

Every page mapped to a real movement — breathe, sway, spin — scored to the story.

Scene library

The book's art regenerated as on-model stills the publisher can use anywhere.

One ingest. Every format. It's one pipeline and one cost, not four product lines — and the rights holder approves all of it before it ships.

Why we're building this

Screen time isn't the problem. Still time is.

Every product built for this moment does the same thing. It limits the screen, locks the app, sets the timer. All of them treat the device as the enemy, and not one of them produces a single minute of movement.

We think that's the wrong answer to the right question. Kids won't read more because the tablet got taken away, and they won't move more because an app shut itself off. They'll move if the thing on the screen requires it.

Books lost the fight

Picture books compete for attention against feeds built by teams of hundreds and tuned never to let go. It was never a fair fight.

The hours are sedentary

Screen hours stack up before a child is old enough to choose otherwise. The habit sets early and it holds.

There's no third option

Parents get one lever: allow it or fight about it. Nothing on the market turns the screen itself into the reason a kid moves.

So we built the third option. Learning and physical activity, in the same twenty minutes, on the device they were going to open anyway.

Live now

Critter Fitter with Bizzy Bee

One book, fully rebuilt. Here's exactly what a session looks like.

The story opens. The original illustrations from the published book, page by page, narrated aloud with the words highlighted as they're read.

Page four ends and the story stops. Bizzy needs help flying. The screen says: flap with Bizzy. Ten flaps to turn the page.

The child flaps. On-device pose tracking counts every rep in real time and the counter climbs. There's no timer and no pressure — the page waits as long as it takes. The camera is how the story moves, so it stays on the whole way through.

Ten reps. The page turns. The story continues, and it does not continue before then.

Twelve pages. Six movement gates. Roughly forty reps across about fifteen minutes.

Runs in the browser

No app install, no hardware, no accessories.

Zero frames uploaded

Pose runs entirely on the device, COPPA-minded by design.

Zero inference cost per session

The unit economics hold at any scale.

Every title also ships as a move-along video — the same story animated and narrated straight through, with movement cues on the beat, for kids who'd rather follow than lead.

ActivePlay Studio

One file in. Six steps. Every format out.

A publisher hands us a PDF. This is everything that happens between that file and a shelf of finished assets — the interactive story, the animated short, the activity map, the scene library. One ingest and one cost produces all of it, not four separate product lines.

Step 01

Ingest

The PDF is read page by page into a scene graph — text, beats, and structure.

Step 02

Cast

Characters are locked to reference sheets so every scene stays on-model.

Step 03

Illustrate

Each page is generated as a scene still in the book's own art direction.

Studio Images tab with generated scene illustrations

Step 04

Activity layer

AI scores the story and maps a real movement to each page — breathe, sway, spin. This is the step no one else is building.

Studio Activity tab mapping movements to pages

Step 05

Narrate

Studio-grade narration is generated and approved clip by clip.

Studio Voice tab with approved narration clips

Step 06

Animate

Stills become animated scenes, synced with narration and published as an experience.

Nothing generates without sign-off. Every scene and every line of narration is approved before a dollar is spent — by our team, and by the rights holder.

We only convert titles we're licensed to convert. The author or publisher approves the output before it ships, and their name stays on it.

The bigger idea

Books are the wedge. They aren't the business.

Strip away the story and what's left is a small, general machine: pose in, progression out. It doesn't care whether the thing being gated is a page, a scene, or a level. Books are simply where the rights are cleanest and the partners are willing.

Now

Picture books

Real catalogs from real authors, rebuilt page by page. Licensed, revenue-shared, live today.

Animated video

The same stories as narrated shorts with movement cues on the beat, distributed where kids already watch.

Then

The platforms kids choose themselves

Movement as the unlock mechanic inside the games and video they open on their own. That's where the hours actually are, and that's the layer everything is pointed at.

Every hour a child spends on a screen is an hour that could be asking something of their body. We're building the layer that makes it ask.
