Live Caption Translate users statistics

Real-time captions and translation for the audio playing in any browser tab.

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.
