Record meetings, interviews, lectures, classes, and conversations on iPhone, iPad and Apple Watch. See the transcript live, translate across languages, identify who said what, and find any moment again later. ■ We offer AI experts that fit your job. We provide fastest AI models for everyday recording, high-accuracy AI models when every word matters, and multilingual AI models for different languages. Switch AI models anytime anywhere with a single click, even with your old recordings. ■ Remember people, not just recordings. Local AI keeps track of speakers across recordings, helping you recognize the same people through meetings, interviews, and special memories. ► So instead of only searching for what was said, you can find who said it. ■ Never lose the original moment. A transcript should always lead you back to the source. Every sentence stays connected to its exact moment in the recording. Tap any line to instantly replay the original audio and hear exactly how it was said. No more scrubbing through an hour-long recording to find one sentence. When something becomes a task, export it directly to Apple Reminders. ■ Record beyond your iPhone. Start a recording from Apple Watch when taking out your phone isn’t convenient. Import existing audio and turn old recordings into searchable transcripts. Your recordings become more useful over time instead of disappearing into a folder you never open again. ■ Privacy when you need it the most. Your audio never leaves your device.
