Founder story
Why I'm building this.
I’m a hard‑of‑hearing dad who built voice captions so I could finally keep up with my hearing son. After years of gaming and missing callouts, I know how frustrating it is to be left out of the action. I wanted to fully join those fast, chaotic matches—so I built the tool I always needed. Now you can use it too.
Your team is shouting directions and enemy positions, and you’re stuck asking for repeats or guessing.
I built CaptionsRush so I could finally follow my squad in real time. No hacks — just captions that match the pace of the game. If that’s your struggle too, it’s for you.
Three steps
How CaptionsRush works.

What it does
Real-time captions for Discord voice chat.
Per-Speaker + Diarization
Each teammate gets their own stream on Discord — and System Audio mode tags speakers via diarization even when voices overlap, interrupt, or switch rapidly. You always know who said what.
Word-by-Word Streaming
Under 50ms latency. No waiting for pauses or sentence endings — captions land as the callout lands.
125+ Languages
125+ languages on cloud for transcription and diarization. Real-time translation covers 60+ of them.
Optional Auto Start / Stop (Cloud only)
Automatically starts and stops captions when no audio is detected. No more forgetting to turn it on or off.
Real-Time Translation (Cloud only)
Your teammate speaks Spanish, you read English — translated word by word as they talk. Any-to-any across 60+ languages. Included on every cloud plan.
Any Game, Any Audio
Discord, Twitch, YouTube, Zoom, WhatsApp — if it plays audio on your desktop, it gets captions.
Tone Tags — World First (Cloud only)
See how it was meant, not just what was said: [teasing], [frustrated], [sarcastic], [scared], [shouting] and more, next to each speaker as they talk.
Audio Description (Cloud only)
AI detects [Laughter], [Footsteps], [Music] — not just words. Hear the full picture.
Built for Messy Comms
Every word right across accents, numbers, callsigns, and domain-specific terms — even in fast, overlapping, multi-speaker game chat. Funded by community supporters.
Different barrier, same overlay
Your team doesn't speak your language either?
Live translation across 60+ languages — word by word, mid-sentence, any language into any other. Teammates can even switch languages mid-callout.
Captions for everyone. Funded by the community.
