Everything you need for
better comprehension
From live meetings to uploaded voice notes — Buzz handles it all, privately and accurately.
Live Captions
Real-time speech-to-text streamed over WebSocket with sub-second latency. Powered by Deepgram Nova-3, Sarvam, and Gladia.
Live Translation
Translate captions in real time to English, Spanish, French, Japanese, Hindi, Arabic, and more — via DeepL, Sarvam, and Google.
Speaker Diarization
Automatically identify and label multiple speakers. Rename "Speaker 1" to "Alice" — labels persist across your session history.
Voice Note Import
Upload MP3, M4A, OGG, WAV, CAF, and more — up to 50 MB. Transcribe WhatsApp voice messages, iMessage audio, or recordings.
Session History
Every session is saved and searchable. Edit transcript segments, fix names, add corrections — your history, your words.
