Rango is an AI meeting assistant you invite to your calls by email, just like a human participant. It joins Zoom, Google Meet, or Microsoft Teams meetings without requiring any app installation, completing setup in about 20 seconds. During the call, Rango takes notes, produces a transcript, and can answer questions out loud when addressed. A free tier allows one meeting of up to 30 minutes at no cost, with notes and transcripts retained for one week.
