FutureTalk 🎙️✨

FutureTalk is a state-of-the-art AI-powered translation app designed to break language barriers effortlessly. Built with React Native (Expo SDK 54) and optimized for speed and context, it leverages OpenAI's latest models for real-time transcription, translation, and summarization.

A modern, premium landing page that guides you through the app's capabilities. Features a sleek design with card-based navigation and a "Coming Soon" section for future-ready features like Offline mode.

Classic two-way voice translation.

• Voice-to-Voice: Select your target language and speak. The app transcribes your voice (Whisper) and translates it (GPT-4o-mini).
• Instant Playback: Automatically reads the translation back using high-quality OpenAI TTS voices.
• Bi-directional: Switch between languages in a tap for fluid conversations.

Need to follow a long lecture or an English video? Listen Mode is built for continuous, background-ready understanding.

• Continuous 15s Recording: Never miss a word. The app captures 15-second audio chunks in a seamless loop.
• Background Processing Agent: A dedicated agent handles transcription and translation while you keep recording the next segment.
• Live German Transcript: Displays the conversation in real-time, translated into German.
• Context Awareness: Each chunk uses the context from the previous sentence for superior sentence flow.
• AI-Powered Summaries: Automatically generates a beautifully formatted, bulleted summary of everything said—updated every 45 seconds or when you stop recording.
