Your child pops bubbles. Catball turns them into a story. A new adventure, every day.

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