Step-by-step live tutorial on building a voice AI assistant (Jarvis) as a React Native mobile app using ElevenLabs conversational agents. Covers creating an ElevenLabs agent, integrating the React Native SDK with LiveKit for WebRTC, setting up Expo Router for navigation, implementing client-side tools (voice navigation, console logging), server-side webhook tools (weather API), connecting MCP servers (CoinGecko for crypto prices), and beginning a secure Google Gmail/Calendar integration using Supabase for authentication and token management.
