- Real-time Captioning — Captures tab audio and generates subtitles word-by-word using AI-powered speech recognition (STT), with smooth typing animation for natural readability.
- Live Translation — Translates recognized speech in real-time using streaming AI translation APIs, displaying results token-by-token alongside the original text.
