Real-time simultaneous interpretation on your Mac. Movies, meetings, phone calls — sound goes in, captions and a translated voice come out. Just half a breath behind.

Videos, podcasts, online classes, meetings — system audio flows straight into Tingdong, live captions float on screen, read aloud when you want. A zero-chrome big-screen mode projects captions for the whole room.
Route an iPhone call to your Mac over Bluetooth and the Tingdong microphone takes over: what they say arrives in your language, what you say reaches them in theirs. One switch decides who hears what.
A macOS app — built for your Mac. Requires macOS 26 (Tahoe) or later · Universal for Apple Silicon & Intel.
Signed & notarized by Apple. Version 0.13.0.
No tokens to count, no exchange rates. A cup of coffee buys a month of understanding the world.
Every new device comes with 100 free trial credits — install and go, no signup. Credits come with a fair-use policy: normal watching, meetings and calls won’t hit it; bot-style continuous streaming gets rate-limited.
For most real usage, you won’t finish it. All on captions it’s about 16 hours — several movies a week; an hour of cross-language meetings every workday uses about 60% a month. You’re only charged while sound is coming in — silence is free.
Two fixed public rates, never dynamic: live captions 1 credit/min; translated voice 5 credits/min, counted only while someone is actually speaking — in a real call the duty cycle is roughly 30–50%. Your balance is always visible in the app.
Two ways: wait for next month’s 1000 credits, or buy a $4.99 Credits Pack for an instant top-up (valid 90 days, stackable). A session in flight never gets cut — there’s a soft-landing buffer.
Audio only passes through the real-time recognition channel; Tingdong’s cloud never stores your audio. Transcripts live only on your Mac. Metering records seconds used, not content.
60+ languages translated in any direction — English, Chinese, Japanese, Korean, Spanish, French, German and more, with automatic language detection.
Yes. Members can paste their own Soniox API key under Settings → Advanced; usage then bills to your own account and Tingdong stops metering. A niche option most users never need.
