In meetings or livestreams, Cicada gives you live bilingual subtitles and writes structured meeting notes as it listens. When it's your turn to speak, hold the talk key (right `⌥` on Mac, right `Ctrl` on Windows, customizable) and talk—the other side hears your translated voice right in the call. Cicada listens to system audio directly without sending bots into the meeting, so no one else notices a thing. On Apple silicon Macs, all speech recognition runs on device, so audio never leaves your computer.

**Where it works**: Anything that plays sound on your computer—Tencent Meeting, Feishu, DingTalk, WeCom, Zoom, Teams, Google Meet, Webex, Discord, and Telegram voice chats, plus X Spaces, YouTube, Twitch, Bilibili Live, podcasts, and web pages. On phones, the system blocks recording audio from call and meeting apps—put it on speaker and use In person instead.
