The library cassette · rebuilt for the web

Press play on the stories you make together.

Photos of their drawings. Their voice on every page. A little music underneath. One link that plays anywhere.

READ ALONG. LISTEN. FEEL.

Remember the magic?

Library books with cassette tapes. Reading along while the narrator guided you page by page. Background music that made every story feel alive.

Now any storybook can read itself — in the voice and mood you choose.

THREE SURFACES · ONE FILE

  • StorySync Reader — plays any tape in any browser. No app, no account.

  • StorySync Creator — pictures, voices, a little music and timing, made together.

  • SSYNC Protocol — the open file between them. Like PDF, for storybooks.

Three steps · one tape

How the magic works

  • 01

    Snap your drawings

    Point the camera at a crayon masterpiece. It lands on the page — resized, straightened, and kept right here on your device.

  • 02

    Record your voice

    One tap per page. Their voice, their pauses, their giggles — recorded to the story and normalized to a format every browser can play.

  • 03

    Share one link

    Grandparents open it in any browser. No app, no account, no install — the tape plays the way you made it, music and all.

The open format

.storysync — like PDF, for story experiences

One file holds the pages, the images, the narration, the music bed and the timing, described by a manifest anyone can read. Published narration is always AAC/M4A, so a tape recorded on an Android phone plays on a grandparent’s iPad.

The spec is open and the player is plain web. Write your own reader if you like — nobody needs our servers to hear a story.
