Collaborative Stories

You write a line, the AI writes the next. Each persona has its own personality, voice, and style — from cheerful to spooky to hilariously weird.

Stories come alive as comic book panels with illustrated backgrounds, emoji characters, and speech bubbles. OpenAI users get real DALL-E illustrated panels.

📖

Book Reader

Flip through your story as a comic book with 3D page-turn animation. Tap any panel to hear it read aloud.

Joke Mode

Pick any persona and get jokes told in their unique style. Sunny tells upbeat jokes, Spooky tells creepy-funny ones, Giggles goes full slapstick.

🎤

Voice Input & Output

Speak your story lines instead of typing — perfect for younger kids. AI responses are read aloud automatically.

🔄

Mid-Story Persona Switch
