Live Caption Translate

Overview

Live Caption Translate transcribes the audio playing in any browser tab in real time, translates it into the language you choose, and shows it as a caption overlay right on the page. Lectures, meetings, podcasts, foreign-language videos — add live captions and translation to content that has none. ■ Features - Real-time speech recognition for the audio of any tab - Translation into 20 languages, shown alongside the original - A clean caption overlay at the bottom of the page (fullscreen-aware) - The tab keeps playing its audio normally while captured ■ Speech-to-text — choose one of three - Deepgram: real-time cloud streaming, lowest latency - In-browser Whisper: runs inside the extension, free, no server or key - Local Whisper server: free, processed by a server you run yourself ■ Translation — choose one of two - OpenAI API - A local LLM (Ollama, LM Studio, or any OpenAI-compatible server) ■ Your keys, your data (BYOK) - API keys are stored only in your browser and sent solely to the provider they belong to - With in-browser Whisper + a local LLM, everything runs locally and free, with nothing sent to the cloud ■ How to use 1.
