UMEVO Note Plus is a MagSafe-compatible AI voice recorder that captures both phone calls and in-person meetings through a single device and turns them into transcripts, summaries, and visual notes. A physical switch toggles between a call-recording mode, which uses a vibration-conduction sensor to capture phone conversations, and a note-recording mode, which uses air-conduction microphones for meetings, lectures, and interviews. Recordings are processed through UMEVO's companion platform, which applies a large language model to generate transcripts, translations, speaker-separated dialogue, summary documents, and mind maps across well over 100 languages. The device offers substantial onboard storage and long continuous-recording and standby battery life, and it attaches magnetically to the back of a phone for convenient capture. UMEVO sells several models, including the Note Plus, a lower-cost Note, and a screen-equipped variant, all managed through its app and online platform where users can transcribe, summarize, and ask questions grounded in their recordings. It targets professionals, students, and others who need accurate capture of both calls and live conversations. Pricing varies by plan. Check the official website for current pricing.
