The live AI note taker. Tap record at the start of your meeting, class, or interview. Superscribe writes a transcript as people talk, names each speaker, and turns the conversation into a summary and outline you can browse. Chat and get answers that link to the key moments. Everything links back to the audio so you can check the app's work: tap any word in the transcript, or outline item to jump to that moment. Every chat answer links back to the relevant moments in the recording — tap any of them to play back and hear it for yourself. - Live transcription: words appear on screen the moment they're spoken. Read along as you record, and never lose your place. - Live speaker identification: Superscribe figures out who's talking from the context of the conversation. Fix any mistakes with a tap — no more "Speaker 1, Speaker 2" guessing games. - Live sync across devices: start recording on your iPhone, watch the transcript come in on your iPad, pick it up on the web later. Everything stays in sync. - Tappable transcripts: tap any word to jump straight to that moment in the recording. - Outlines that link to the audio: a short summary plus a section-by-section outline of what was discussed.
