Which languages are supported?

Currently supports English, Vietnamese, and Japanese for both transcription and translation. More languages coming soon.

How does the Chrome extension work?

The extension captures audio from the active browser tab using Chrome's Tab Capture API, sends it for transcription, and displays translated subtitles as an overlay on the page.

The web app and Chrome extension are free. You only need an API key for the speech recognition service (very affordable at ~$0.12/hour of audio).
