Questions
Does Quiet Assistant only work for English meetings?
No. It captions 60 languages and translates between any two of them, so a meeting in Japanese can be read in Spanish, or one in German in Korean.
Do either of them join the call as a bot?
No. Both run on your computer and listen to the call audio, so nobody else in the meeting sees an extra participant.
