Sotto
Sotto listens to a room's conversation and puts helpful public facts on your TV as you talk: who that person was, where that place is, what that word means. No one has to stop and type a question.
Say "Hey Virgil, go deeper" for more on what's on screen. Tell Sotto what the room is (a podcast, a Bible study, a book club, game night) and it adjusts what it shows.
Audio never leaves your iPhone, iPad, or Mac. Sotto is in a private beta.
