Tafsiri: live meeting translation overlays real-time subtitles by listening to a meeting tab, offering on-device speech-to-text and translation for Google Meet, Microsoft Teams, and Zoom in Chrome. Developed by timmwangi as a Chrome extension, it emphasizes local processing and privacy. Key capabilities include automatic spoken-language detection, a movable subtitle window, and one-click transcript export. It fits professionals and students who join web meetings in languages they do not master and need private, in-browser translation.

How Tafsiri captures and displays translated speech during meetings

Tafsiri captures audio from the meeting tab rather than joining as a bot, then produces speech-to-text and translated subtitles in real time. The extension supports roughly 50 languages, including Swahili, Amharic, Hausa, and Zulu, and shows those translations in a draggable, resizable window that can be popped out. One-click export saves the full meeting transcript to the clipboard for later use, which helps workflows that require meeting records.

How it behaves on typical desktop hardware and when Chrome AI is unavailable

The extension performs processing locally, so on-device AI features require a desktop Chrome build that supports those models (Chrome version 138 or newer). When on-device AI is unavailable, Tafsiri can read native captions from the meeting platform instead, maintaining functionality without server-side processing. Source notes describe the extension as lightweight, which aligns with its design to run in a single browser tab and avoid adding a separate meeting participant.

What privacy choices and platform limits mean for users

Tafsiri keeps all audio and translation data on the user's machine and does not send meeting audio to external servers, a fact the developer disclosed. That design reduces exposure to server-side analytics for sensitive calls. The extension works only with web-based Meet, Teams, and Zoom in Chrome, so users of desktop meeting applications must open the browser versions to use its capabilities.

Best for privacy-minded participants who use browser meetings

Tafsiri suits people who need multilingual support inside a browser session and want translations processed locally. It trades broader desktop-app compatibility for on-device privacy and a non-bot workflow. If you join meetings through Chrome and require subtitle translations for under-represented languages, Tafsiri offers a focused, privacy-first approach; users who rely on native desktop clients must use web versions instead.
