Live captions and streaming
You talk. Every viewer reads along in their own language.
Stream a lecture, a talk, a tour or a service. PTT captions it live in whatever language each viewer picks, and reads it aloud in a natural voice for anyone who'd rather listen.
How it works
Go live in three steps.
- 1
Start a stream
Go live from a phone, a webcam or Mentra Live glasses through PTT Bridge.
- 2
Share the player
Send the link, show a QR code on screen, or embed the player on your own website.

Everyone reads along
Each viewer picks a caption language, and can switch to a natural voice if they'd rather listen.
For viewers
The easiest seat in the house.
No account, no download, no squinting at someone else's language.
Pick a language, any language
81 caption languages. Change your mind mid-stream and switch in a tap.
Listen instead of reading
Have the captions read aloud in a natural voice, from 555 to choose from.
Late? Catch up
Every broadcast is recorded with a translated transcript, so latecomers can scroll back.
Watch on anything
Phones, tablets, laptops and big screens. If it has a browser, it has captions.
For hosts
Your stream, on your site, in every language.
Put the player wherever your audience already is, and let PTT handle the languages.
- Embed the player on any web page with one embed code.
- One camera can feed several live players at once.
- Recordings come with a clickable, translated transcript. Click a line and the video jumps there.
- Already recorded? Upload an MP4 or MP3 for captioned, translated playback.

Live captions are produced automatically by AI. They're fast and accurate, and like any automated captioning they can miss a word. When a recording becomes the official record, check what matters.
FAQ
Live caption questions.
Do viewers need an account or an app?
No. Viewers open the page, pick a caption language and watch. They can also have the captions read aloud in a natural voice.

What happens after the stream ends?
Every broadcast is recorded with a clickable, translated transcript. Click a line and the recording jumps to that moment.

Yes. Upload an MP4 or MP3 and PTT turns it into captioned, translated playback.
What can I stream from?
A phone, a computer with a webcam, or Mentra Live smart glasses through PTT Bridge.
