Build a modern mobile app called AI Walkie — an AI-powered push-to-talk communication app that allows users to communicate instantly through voice channels, similar to a traditional walkie-talkie but enhanced with artificial intelligence. Core Features 1. User Authentication * Sign up and log in with email, phone number, Google, or Apple. * Create a username and profile picture. * Allow users to add friends. 2. Push-to-Talk * Create a large central HOLD TO TALK button. * When the user holds the button, record their voice. * Release the button to send the voice message. * Messages should be transmitted with very low latency. * Show speaking status in real time. * Play incoming messages automatically through the speaker. 3. Channels * Create public and private channels. * Join channels using a channel name or invite code. * Show who is currently online. * Show who is speaking. * Allow channel administrators to remove or mute members. 4. AI Assistant Add an AI voice assistant that can: * Understand spoken commands. * Answer questions by voice. * Summarize conversations. * Convert voice to text. * Translate conversations between languages. * Allow users to say commands such as: * “Translate this to Portuguese.” * “Summarize the last five messages.” * “Send this message to Channel 2.” 5. Voice Translation * Detect the language being spoken. * Translate the speech into the selected language. * Convert the translation back into natural-sounding speech. * Support English, Portuguese, Spanish, French, Yoruba, and additional languages. 6. Voice-to-Text * Display a text transcript below each voice message. * Allow users to copy transcripts. * Store transcripts securely. 7. Emergency Mode * Add an optional emergency channel. * Include a large emergency button. * Allow users to send an urgent voice alert to selected contacts. * Include optional location sharing. 8. User Interface Create a clean, modern interface inspired by professional radio/walkie-talkie devices. Main screens: * Splash screen * Login/Register * Home * Walkie-Talkie channel * Channel creation * Channel members * AI Assistant * Conversation history * Friends * Notifications * Profile * Settings Walkie-Talkie Screen The main screen should contain: Channel Name Online Users Current Speaker Large HOLD TO TALK button Microphone status Recent voice messages AI button Mute/Speaker button Channel settings The interface should feel fast and responsive, with animations showing when someone is speaking. Technical Requirements Use: * Flutter or React Native for the mobile application. * WebRTC for real-time voice communication. * Node.js backend. * PostgreSQL or Supabase database. * Secure authentication. * Push notifications. * WebSocket-based real-time events. * An AI real-time voice API for the AI assistant. * Speech-to-text and text-to-speech services. Design the architecture so that voice communication is handled separately from normal application data to maintain low latency. Security Implement: * Encrypted communication where appropriate. * Secure authentication. * User permissions. * Private channels. * Channel invite codes. * Rate limiting. * Secure storage of user information. * Microphone permission handling. * Location permission handling only when the user enables location sharing. Important Do NOT build this as a simple voice-message chat app. The primary experience should feel like a real-time walkie-talkie: users hold a button, speak, release it, and other connected users hear the message immediately. Build the project with clean, scalable code and a professional UI. Start with an MVP containing authentication, channels, real-time push-to-talk voice communication, and the AI assistant, then structure the project so additional features can easily be added later.
