Realtime captions
Deepgram Nova-3 streaming transcription with interim + final results. Broadcast-style roll-up subtitles your audience can actually read.
OSC · NDI · Spout
Push a transparent caption frame to NDI and Spout, and the live text string over OSC - straight into OBS, vMix, Resolume or TouchDesigner.
Any audio source
Caption a microphone or any system-loopback device - a call, a video player, a live feed. Pick the device and go.
