Talking to people? Get the desktop app for Mac or Windows — it translates live calls, meetings and conversations. Watching YouTube? Get the free Chrome extension. They are separate products, installed separately.
Real-time speech translation on your Mac or Windows PC. Hear any call, meeting or video in your language and speak back through a virtual microphone — in 60+ languages, with natural voices.
Translate and AI-dub any YouTube video in your browser — subtitles in 100+ languages, natural voice-over, SRT export and AI summary. Not for calls or meetings.
Each one is a short page about that situation.
