Cassette turns your iPhone into a cassette deck that listens, then writes it all down. Press RECORD for a meeting, a lecture, an interview or a quick voice memo. When you stop, Cassette writes: • A transcript with timestamps and who said what. Tap a line to hear that moment again. • Notes in the shape of the recording: meeting, 1:1, lecture, interview, client call, doctor's visit, brainstorm or voice note • Action items, with owners and due dates only when someone actually said them • Highlights, the lines worth remembering • A follow-up email draft for everyone who was there • Study cards from your lectures WRITTEN AS YOU RECORD On iOS 26 and later the transcript is written while you record, so it's ready the moment you press STOP. GOT A RECORDING ALREADY? Share a voice memo or an audio file to Cassette, or press ADD FILE on the Shelf, and it becomes a tape with a transcript and notes like any other. Cassette reads M4A, MP3, WAV, AAC, FLAC, Opus and the sound in MP4. Your original file isn't changed. ASK YOUR TAPES "What's due this week?" "What did we decide?" Ask across all your tapes and get the answer from what was really said, each line pointing at its moment. PRIVATE BY DESIGN Transcripts come from Apple speech recognition, and your notes are written by Apple's own models, never by an outside AI service. Turn on On-device only and your recordings, transcripts and notes never leave your iPhone. No ads, no tracking. YOUR NOTES, IN YOUR NOTES APP One key sends a tape's notes or transcript to Apple Notes, Microsoft OneNote, Notion, Evernote or Google Keep, organized and ready to use: the summary, decisions, action items with who and when, and key points. Sign in to OneNote once and every tape can go there by itself. The follow-up email is ready when a tape is done, notes save as Markdown in Files, Cassette works with Shortcuts and Siri, and every tape exports at once. A DECK YOU CAN FEEL Piano keys you press, a tape counter, VU meters, side A and B, and a speed knob for playback. Press MARK while recording and that moment shows up in your highlights. ONE TAP TO RECORD Start a tape from a Home Screen or Lock Screen widget, or from Control Center, and follow the recording in the Dynamic Island. ON YOUR WRIST Record with Apple Watch: RECORD, PAUSE and STOP are on your wrist, and when you stop, the tape goes to your iPhone, which writes the transcript and notes. Start a tape from your watch face, from Control Center or with Siri. ON IPAD AND MAC On iPad, your notes open beside the deck. On the Mac, the same deck sits in a small window beside your video call and records the call and your microphone together, with no bot joining the call. FIND ANYTHING Search your shelf by title, by person or by any word that was said. Copy a whole tab, or save it as a PDF or Word document. YOUR TAPES, BACKED UP Use Cassette without an account. Sign in with Apple, Google or email, and with Premium your recordings, transcripts and notes are backed up and come back on a new device. Delete a tape, or your account, at any time. FREE AND PREMIUM Recording is free and unlimited, with no minute meter. Transcripts and notes are free for a few tapes each month. Cassette Premium transcribes and writes up every tape and backs up your shelf: weekly, monthly, or annual with a 7-day free trial, or pay once with Lifetime. One Premium covers Cassette on iPhone, iPad and Mac. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period. Terms: https://onelifeco.app/termsofservice Notes by Apple Intelligence need a compatible iPhone. On other iPhones, Cassette writes simpler notes on the device.
