You will get an AI voice agent for your Flutter mobile app
Top Rated

Project details
Voice is the next interface. I build AI voice agents directly inside Flutter mobile apps so your users can speak naturally and get intelligent responses, not just commands.
What's included:
• Speech-to-text integration (Whisper / Google Speech)
• LLM processing (OpenAI GPT-4o, Claude, or Gemini)
• Text-to-speech response (ElevenLabs or native TTS)
• Custom AI persona and system prompt tuning
• Conversation memory and context handling
• Clean Flutter UI with voice waveform animation
• Secure API handling keys never exposed client-side
Use cases: AI fitness coach, language learning tutor, voice-controlled productivity app, customer support agent, medical intake assistant.
Send me your app concept and I'll confirm what's buildable in your budget within a few hours.

What I build:
— AI-powered mobile apps (Flutter + OpenAI / Claude / Gemini)
Chat assistants, AI coaching apps, LLM-integrated workflows, real-time AI features inside existing apps
— Enterprise XR & Unity simulations
Training simulations, serious games, AR/VR prototypes for industrial and medical clients, Photon multiplayer, cross-platform deployment
— Flutter apps from MVP to App Store
Full-cycle development: architecture, Firebase backend, payment integration, App Store + Play Store submission
Why clients work with me:
→ I've maintained a $10K+ long-term engagement for a single client — I'm not a one-project developer
→ Production-ready code with clean architecture, not copy-paste tutorials
→ I flag problems before they become blockers, not after
→ Fast response, honest timelines, zero scope surprises

Flutter · Dart · Unity · C# · Firebase · Node.js · OpenAI API · Claude API · Gemini · REST APIs · Photon · AR Foundation · XR Toolkit · .NET · Angular · React · Figma
