Only for Mac

$9.99 · In‑App Purchases

Mac

Live subtitles for anything your Mac plays, and a two-way interpreter for face-to-face talk. Everything runs on your Mac. Also on iPhone, one purchase. Free for 30 days. Understand foreign-language videos, streams, calls and classes on your Mac, in English or your own language, as it happens. Live Sound Translator listens to the sound your Mac is playing, turns the speech into text, translates it, and shows it as floating subtitles over whatever you are watching. PRIVATE BY DESIGN • Speech recognition runs entirely on your Mac. Your audio is never recorded, stored or sent anywhere. • Translation is on-device by default, using Apple's built-in translation. With the default setup, nothing you listen to leaves your Mac. • No account. No tracking. No analytics. No ads. YOUR CHOICE OF AI, WHEN YOU WANT IT Want more natural translations? Connect an AI provider you trust: • OpenRouter: sign in in your browser, paste one short code, and pick from hundreds of AI models • Claude (Anthropic), with your own API key • Any OpenAI-compatible service • A model running on your own Mac, such as Ollama or LM Studio, to stay fully offline Please note: with a cloud AI provider, the transcribed text (never the audio) is sent directly from your Mac to that provider, which handles it under its own privacy policy. The app asks before it first sends text to a service. TALK FACE TO FACE A Conversation window turns your Mac into a two-way interpreter, the same as the iPhone app: • Click their language and they speak: what they say appears translated, as a conversation • Click your language and speak, or type: when you pause, your reply is translated and read aloud in their language • Every conversation is kept on your Mac, to read again or share as text or subtitles • Works offline once the languages are downloaded; Downloaded Languages manages them in one place MADE FOR WATCHING • Subtitles appear while people are still speaking, then settle into the final sentence • Every line stays up long enough to read, at a reading speed you choose • Conversations: tells up to four speakers apart, on your Mac, with coloured names on the subtitles and a transcript that reads like a dialogue. Rename speakers with a click • See the original text above the translation, or just the translation, each at its own size • Pinyin under Chinese text, on or off • A floating panel that stays above your other windows and never blocks your clicks. Resize it to see more: it shows as many recent messages as fit, like a running conversation • Choose the font, size, colours, background and number of lines • Listen to everything your Mac plays, or pick the apps: search open apps, choose several, or browse for any installed app KEEP WHAT YOU HEARD • A transcript of the current session, with timestamps • Export as plain text or as an .srt subtitle file EVERYTHING IS ADJUSTABLE • Spoken languages: Chinese (Mandarin and Cantonese), English, Japanese, Korean, Spanish, French, German, Italian and Portuguese • On-device translation between about 20 languages, including Vietnamese, Chinese, English, Japanese, Korean, Thai and Indonesian; AI providers can translate into many more • Global keyboard shortcuts to start, stop and show or hide subtitles • The app itself speaks your language: English, 简体中文, 繁體中文, Español, हिन्दी, العربية, Português, Français, Deutsch, 日本語, 한국어, Русский, Italiano, Türkçe, Tiếng Việt, ไทย and Bahasa Indonesia FAIR PRICING Free to use for 30 days with every feature. After that, a single one-time purchase unlocks the app forever, on your Mac and in Live Sound Translator for iPhone. No subscription, and the trial never charges you or renews into anything. GOOD TO KNOW • Requires macOS 26 or later on a Mac with Apple silicon. • macOS asks you to allow System Audio Recording the first time you start listening to your Mac's sound, and Microphone the first time you use the microphone or the Conversation window. • On-device speech models and translation languages are downloaded by macOS the first time you use them. • AI providers bill you directly for the use of your own API key.
