Relay
Live captions in your viewers' language — as you speak.
You talk. Relay writes it on your stream — word by word, translated as you go. The viewers who don't speak your language read along in theirs, and nobody misses a callout, a joke, or a clutch play.

How it works
Why streamers run it
Captions in about a second
Words land on stream while you're still saying them — typing out live, then snapping clean when you pause.
Grow past your language
Stream in Português, get read in English — or any pair. Your community stops being capped at one language.
Gets your world right
Teach it your guild names, spells, and slang once — Relay spells them exactly right, every time.
Looks like your stream
A caption card, broadcast TV captions, or a pixel-faithful game chat window — dragged, scaled, and recolored on a real 1080p canvas.
Nothing to babysit
Start it from Loop and go live. It captions the whole session — no push-to-talk, no re-syncing, no mid-stream fiddling.
Free, private, yours
Runs entirely on your PC. No subscriptions, no API keys, no per-minute fees — and your voice never leaves your desk.
