Live translation Paid plan

Show your captions in another language, live — translation only, original only, or both.

Speaker labels Paid plan

Automatically tag who's talking so multi-person streams stay easy to follow.

Built for OBS

Send captions to an OBS browser source, a transparent always-on-top overlay, or a dedicated capture window.
