Live translated subtitles for webinars and livestreams

Published October 14, 2026

A webinar reaches people everywhere, and many of them read your language better than they hear it, or don't speak it at all. Meeting apps can show captions, but translated captions often need a higher plan, and every viewer has to find and turn them on. Tapy Live puts the translation into the picture itself, so everyone sees it, in any meeting app or stream.

Two ways to do it

• Share a window: the quickest, and it works in any meeting app.
• OBS: subtitles over your camera or slides, for a polished stream or a virtual camera.

Way 1: share the subtitle window

1. Open Tapy Live in its own browser window, pick the languages, and press the mic.
2. Arrange your screen: slides on top, and a short, wide Tapy Live window below them as a strip.
3. In Zoom, Teams or Google Meet, share your whole screen. In Zoom you can share just the part with the slides and the strip (Share › Advanced › Portion of Screen).

If you only need the subtitles, share the Tapy Live window on its own. In Google Meet, presenting a Chrome tab works too.

Way 2: OBS with a green screen

OBS Studio is free, and it can lay the subtitles over anything: your camera, your slides, or both.

1. In Tapy Live, set Screen to green and choose Subtitles only. Pick a bold font and any text color but green.
2. In OBS, add a source that captures the Tapy Live window (Window Capture, or macOS Screen Capture on a Mac).
3. Right-click the source › Filters › add Chroma Key, with Key Color Type set to Green. The green disappears and only the subtitles stay.
4. Place the subtitles at the bottom of your scene, over the camera or the slides.
5. Stream to YouTube or Facebook Live from OBS, or press Start Virtual Camera and choose OBS Virtual Camera as your camera in Zoom, Teams or Google Meet.

Over a busy picture, keep a box behind the text (Background): it stays after the green is gone, and the words stay readable.

Sound in a webinar

Tapy Live listens to the microphone you pick, so it subtitles you, not the other people on the call. Your meeting app and Tapy Live can usually share one microphone. If Tapy Live says another app is using it, pick another microphone, such as a USB microphone, for one of them.

Before you go live

1. Make a test call with a colleague, and check they can read the subtitles at their window size.
2. Check that your hours cover the whole webinar.
3. Don't minimize the Tapy Live window. A minimized window shows nothing to OBS or to your meeting app.
