AI Assistant
AI assistant is a mobile application with a voice AI character
MVP of an iOS and Android app with an animated voice AI assistant, speech recognition and voice responses, subscriptions, and a simple interface.
History of the project
The client needed a clear MVP of an AI assistant focused on voice interaction and a lively 2D character that could switch between states: idle, listening, thinking, and responding. The product was designed as an accessible entry point to AI services for a broad audience, including users who find complex interfaces and text-based interactions difficult.
Customer's wishes
Voice-based interaction flow
Animated character
Subscription model
Secure architecture
Customer's pain
The main challenge was to combine several complex processes into one simple user flow: wake word, voice recording, STT, AI model request, response generation, TTS, and animation sync. At the same time, the architecture had to remain scalable, allowing new AI services, characters, subscriptions, and secure user data handling.
Solution
We built an MVP mobile app in Flutter with a backend architecture based on Supabase and Edge Functions. This made it possible to unify authentication, data storage, subscriptions, payments, media, and AI integrations in one system. The voice flow was powered by SaluteSpeech and DeepSeek AI, while an animated character visually guided each dialogue stage and made the experience more natural.
The process of working on a project
Business analysis
Defined the MVP, key user flows, and monetization logic. From the start, we built a foundation for product scaling and future AI expansion.
Design
Designed a simple and friendly interface centered around a live AI character and voice interaction. The UX was built to feel intuitive for a wide audience.
Development
Built a cross-platform Flutter app and backend infrastructure with AI integrations, subscriptions, and secure data storage.
Testing
Tested the stability of the voice flow, AI responses, character animations, and payment logic. Special attention was given to reliability and ease of use.
Preparation for the release
Prepared the app for store launch, finalized the infrastructure, and made the MVP ready for market release.
Application functionality
The app combines a voice-first flow, an animated character, a subscription model, and core user settings within one simple interface. The MVP was designed to be accessible for a wide audience while staying ready for future scaling.
Main functions
User Profile
The profile brings together all key app settings in one place: account management, character selection, theme switching, document access, and support. This approach keeps the MVP simple and intuitive, without extra screens or overloaded navigation.
Subscription and Payments
The app includes a built-in subscription model with plan selection, payment flow, auto-renewal, and payment history. Users can manage their subscription with ease, while the business gets a monetization-ready MVP from day one.
Voice AI Character
The main screen is built around an animated AI character that guides the user through every stage of the dialogue. The assistant changes states — idle, listening, thinking, and responding — making the interaction feel much more natural than a regular text chat.
The goal was to create not just an AI chat, but a clear voice assistant with a lively visual identity. The team proposed a solution that covered the MVP goals while leaving room for further product growth and new AI capabilities.
Customer feedback
Result
As a result, we delivered an MVP mobile AI assistant for iOS and Android with a clear voice interaction flow, an animated character, a subscription model, and a modern backend architecture. The product became a strong foundation for future growth: connecting new AI services, adding more characters, and expanding functionality without rebuilding the system.
