Live captions for Twitch, YouTube and Kick

Twitch

Caption your talk and game audio and composite it into your OBS or Streamlabs scene, so your Twitch chat and viewers see realtime closed captions burned into the stream.

YouTube Live

Add on-screen captions to your YouTube Live broadcast through OBS or vMix. Great for tutorials, IRL and long streams where viewers watch on mute.

Kick

Kick has no built-in captions, so burn them in yourself: caption in LiveSubs, layer it into your scene, and go live with accessible captions.

Works with your setup

OBS, Streamlabs Desktop and vMix all accept the LiveSubs caption layer over NDI or Spout, or the text over OSC.

Captions game and voice

Caption your mic, your game or desktop audio, or a co-host on a call, by picking a system-loopback device.

More watch time

Captioned streams get followed on mute and are easier to clip, which helps retention and discovery.

Cheap for creators

Pay per minute at $0.04/min with no subscription, so an occasional stream costs almost nothing.

How do I add live captions to a Twitch or YouTube stream?

Caption your mic or game audio in LiveSubs, then bring the caption layer into OBS, Streamlabs or vMix as an NDI or Spout source (or drive a text source over OSC) and position it on your scene. Because it is composited into your scene, the captions are burned into the stream your Twitch, YouTube Live or Kick viewers watch.

Does it work with OBS and Streamlabs?

Yes. Both accept an NDI or Spout2 source, which is exactly what LiveSubs outputs. See the dedicated OBS guide for step-by-step setup.

Can it caption my game audio, not just my microphone?

Yes. Pick a system-loopback device as the audio source and LiveSubs captions whatever is playing on the PC, including your game, a video, or a guest on a Discord call.

How much does it cost for a streamer?

A flat $0.04 per minute, prepaid, with no subscription. You only pay for the minutes you actually caption, so a couple of hours of streaming costs a few dollars.
