In its latest update, Web Captioner gets Chromecast integration, autostart, the ability to export/restore settings, and more.

Highlights of this release:

Cast to a TV with Chromecast

Have a Chromecast? Now you can cast your live captions directly to a TV.

Export/Restore Settings

You can now export settings to a JSON file and restore settings using that file. There's also an option to clear out all of Web Captioner's settings.

Try It


If you want a way to quickly start captioning, you can now visit If you haven’t given Web Captioner permission to use your microphone yet, you’ll have to do that once.

Larger Screen Layout

An option for larger captioning controls makes it easier to start/stop captioning, clear the transcript, and save to a file on a touch screen. This mode also enables certain one-button keyboard shortcuts.

Try It

Webhooks (Preview)

Webhooks allows you to receive real-time HTTP notifications of captioning events in your application. Events are sent client-side from your browser.

This feature's still in progress, so it may change in the future. Let me know how it works for you!
