About Yasso

Yasso is an AI-powered children's storybook app available on iOS and Android that creates personalized, illustrated, and narrated bedtime stories for children aged 3 to 10. Parents describe a character, theme, or moral lesson, and Yasso generates a complete multi-chapter story with unique AI illustrations in 13 art styles — including Pixar 3D, Watercolor, Anime, and Classic Storybook — and warm AI narration. Unlike generic story library apps, every Yasso story is unique: your child can be the hero, and each story serves a purpose you choose. Yasso is COPPA-compliant with no ads, no tracking, and no data collected from children.

Frequently Asked Questions About Yasso

Everything you need to know about Yasso.

Absolutely. Yasso is COPPA-compliant and built with child safety as the top priority. There are no ads, no tracking, and no data collected from children. All content is AI-generated with safety filters, and the app is managed through parent accounts. Your child's privacy and safety come first.
You provide a short description — a theme, characters, or moral lesson — and Yasso's AI generates a complete multi-chapter story with age-appropriate language, engaging characters, and meaningful lessons. Each sentence is paired with a unique illustration in your chosen art style, and the entire story is narrated with a warm AI voice.
Yes! After Yasso generates your story, you can review and adjust the text, regenerate specific illustrations, and choose different narration voices. You have full creative control to make the story perfect for your child.
Record a short voice sample (about 30 seconds) and Yasso's AI creates a natural-sounding clone of your voice. Your child can then hear their stories narrated by Mom, Dad, Grandma, or any family member. You can add multiple family voices depending on your plan. Voice data is encrypted and stored securely — only your family has access.
Yasso creates stories for children aged 3 to 10. The AI adjusts vocabulary, sentence complexity, and story themes based on the age range you select. Younger children get simpler, shorter stories with vibrant illustrations, while older children get richer narratives with more complex plots.
Story creation requires an internet connection since it uses AI to generate text, illustrations, and narration. However, all your saved stories are available offline. You can read, listen to, and enjoy any previously created story without an internet connection — perfect for road trips and flights.
Subscriptions are managed through the App Store (iOS) or Google Play (Android). You can cancel anytime from your device's subscription settings. There are no cancellation fees, and you'll keep access to Pro features until the end of your current billing period.
Yasso offers 13 beautiful illustration styles: Pixar 3D, Watercolor, Classic Storybook, Soft 3D, Pencil Sketch, Anime, Paper Craft, Comic Book, Flat Vector, Line Art, Japanese Ink, Crayon, and Origami. Every story — including your free first story — has access to all styles. New art styles are added based on parent feedback.
Yes, completely. Yasso does not collect any personal data from children. Accounts are created and managed by parents.
