Live Caption Translate

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. Pick your speech-to-text and translation options on the settings page
2. On a tab with audio, click the extension icon and press "Start captions"
3. The original and translated captions appear at the bottom of the page

Note: Browser-internal pages (chrome://, the extension store, etc.) cannot
be captured.
