Pop

Five bubbles. Five words.

Your child taps floating bubbles, each with a word inside. Those five words become the ingredients for today's story.

Read

A story only they have ever read.

An AI writes a personalized story using their words, their name, and Catball — a round, curious cat who finds everything fascinating and always needs their help. Your child is the hero.

Tap

Tap any word to hear it.

Every word in the story is tappable. Tap to hear it spoken aloud. No shame, no interruption. Just a voice saying the word so they can keep reading.

Learn

Words come back.

Bubblebook remembers what your child is learning and quietly brings those words back in future stories. No flashcards. No drills. Just stories that get smarter.

One story per day.

Not ten. Not unlimited. One. Your child reads it, celebrates how many words they read, and Catball says goodnight. Tomorrow there will be new bubbles, new words, a new adventure.

Five minutes of screen time you feel good about.

A growing library of adventures.

Every story is saved. Over weeks and months, your child builds a personal bookshelf of adventures no one else has ever read. Forty-seven stories. Then a hundred. All theirs.

"I wonder what we'll do tomorrow."

— Catball, at the end of every story

Available in 30 languages. For kids 5–10.
