Mosaic
AI
We partnered with Mosaic to design and build a scalable, production-ready app with polished user flows and growth-focused architecture.
Insight & Execution
We partnered with the Mosaic team to bring their vision to life: an AI-powered mobile app that empowers children aged 3–12 to create personalized, moral-infused bedtime stories. Our discovery phase began with understanding the dual audience—children seeking imaginative adventures and parents wanting safe, educational content for their kids. Through collaborative workshops and market research across the US and India, we identified key challenges: maintaining age-appropriate content safety, balancing creative freedom with parental controls, and designing an interface simple enough for young children yet robust enough for meaningful storytelling. Our research revealed three critical insights that shaped the product strategy. First, children needed instant gratification—waiting too long for story generation would lead to abandonment, so we designed a "while you wait" feature showcasing curated 30-second stories from other users. Second, personalization drove engagement: pre-filling user data from previous sessions while allowing edits reduced friction and encouraged repeat story creation. Third, the freemium model needed careful calibration—offering one free story per day created habit formation while premium subscriptions ($4.99 for 100 stories/month) provided clear value for power users.
We established the product vision: "Foster a love for storytelling and learning through personalized, AI-powered, multi-language bedtime stories available on any mobile device." This became our north star, guiding every design and development decision. The strategic pillars emerged clearly: safety first (COPPA-compliant content moderation and prompt filtering), magical user experience (cute, dreamy aesthetics with animal mascots and vibrant colors), and community-driven discovery (browsing stories created by peers, rating systems, and social sharing). We mapped the entire user journey—from first-time onboarding collecting age and preferences, through the wizard-style story creation flow with character selection and moral lessons, to audio playback with Text-to-Speech narration and AI-generated illustrations, culminating in sharing achievements with friends and family.

Design & Deployment
The design phase centered on creating a cute, dreamy, vibrant aesthetic inspired by the warmth of bedtime rituals. We developed a comprehensive design system featuring rounded sans-serif typography for maximum legibility, a color palette of sky blue, lavender, and sunshine yellow that felt both calming and playful, and charming animal mascots that guided children through the app. Every interaction was designed with young users in mind: large tap targets, high contrast modes for accessibility, voice-over support, and intuitive bottom tab navigation (Home, My Stories, Create, Profile). We built the complete application using Flutter for cross-platform consistency across Android and iOS, ensuring a shared codebase that accelerated development while maintaining native performance. The backend architecture leveraged Node.js with Firebase, providing real-time synchronization, secure authentication via Google Sign-In, and Firestore for scalable story storage. We integrated cutting-edge AI capabilities: OpenAI/Gemini APIs for generating age-appropriate stories with customizable characters and moral lessons, Google Cloud Text-to-Speech for multi-language audio narration (MVP English, with Hindi and Spanish planned), and DALL·E for creating one beautiful illustration per story that brought each tale to vivid life.
Key features we delivered included the intelligent story generation system with a chapter-based structure (2–3 chapters per story, 3–5 minutes total), pre-filled user personas that remembered preferences while allowing edits, and content safety filters ensuring every story was appropriate for children. The audio experience transformed stories into immersive bedtime experiences with professional TTS narration. The community library enabled children to browse, rate (1–5 stars), and draw inspiration from stories created by peers worldwide, fostering creativity and social connection. We implemented a "Suggest a change" feature allowing users to re-prompt and regenerate stories with AI, putting creative control in young hands. Monetization was seamlessly integrated through Stripe payment processing supporting the freemium model: one free story per day with access to public stories, or premium subscriptions unlocking 100 stories per month with unlimited listening and convenient top-ups ($1.99 for 10 stories). We built a robust referral system incentivizing users to share the app on WhatsApp, Instagram, and Facebook in exchange for bonus stories or premium trial access. The user profile and story management system provided complete control—view, regenerate, delete, share, and rate stories—while tracking subscription status and usage analytics. We ensured complete legal compliance and privacy protection with COPPA-compliant Terms and Conditions, age gates, account deletion options, and data consent management. Security features included prompt moderation filters blocking unsafe or violent content, rate-limiting to prevent API abuse, and comprehensive usage logs with abuse reporting. The technical infrastructure supported high scalability with MongoDB database architecture, Firebase Auth for seamless authentication, and cloud-based services ensuring fast global performance. At project completion, we delivered the fully functional Android and iOS applications with simultaneous App Store and Google Play Store deployment, complete with optimized store listings, screenshots, preview videos, and ASO (App Store Optimization) metadata. We provided comprehensive documentation including design system files in Figma with all UI components and style guides, developer handoff materials with API documentation and integration guides, testing protocols covering family & friends beta testing plus manual QA procedures, and analytics dashboards tracking KPIs: Daily Active Users (DAUs), stories created per user, subscription conversion rates, average playback time, rating scores, and content customization percentages. The launch successfully validated the product across US and India markets, establishing Mosaic as a platform where technology meets imagination—transforming bedtime into a creative, educational, and magical experience for children and parents alike. Every story generated represented not just content, but a moment of connection, learning, and wonder.
