That is a problem for meeting software, where the location of the data matters as much as the quality of the transcript.</p> <h2> How we separated the choices </h2> <p>HyNote records microphone and system audio directly on the Mac, so a bot does not need to join the meeting.</p> <p>For transcription, a supported Mac can process audio on-device after the required model is ready. The first setup can still require a sign-in, an internet connection, and model downloads. On-device transcription describes the processing path; it does not automatically describe where the notebook is stored.</p> <p>Storage is a separate choice. To keep a notebook on the Mac, the user selects <strong>On This Mac</strong> before recording or importing audio. We made that choice visible instead of treating “local” as one broad promise.</p> <p>AI summaries are another layer. Local AI has stricter requirements than recording and transcription: Apple Silicon, macOS 26.4 or later, and Apple Intelligence ready on the device. Online AI remains an optional paid path.</p> <h2> The product lesson </h2> <p>A single “local” badge hides too much. Clearer labels answer concrete questions:</p> <ul> <li> <strong>On-device transcription</strong>: where speech becomes text</li> <li> <strong>On This Mac</strong>: where the notebook is stored</li> <li> <strong>Local AI</strong>: where supported AI processing runs</li> <li> <strong>Online AI</strong>: when a cloud service is used</li> </ul> <p>This also makes limitations easier to explain. HyNote itself supports macOS 14 or later on Intel and Apple Silicon, while some local AI features need a newer Apple Silicon setup. Putting those requirements next to the relevant feature is more useful than a blanket compatibility claim.</p> <h2> What is available now </h2> <p>The Mac app can capture microphone and system audio, show a live transcript, and save the result as a notebook. Core recording and supported on-device transcription are free. System Audio permission is required for capturing meeting audio, and the app does not record the video on the screen.</p> <p>You can see the current Mac build and setup details here: <a href="https://hynote.ai/downloads/mac" rel="noopener noreferrer">HyNote for Mac</a></p> <p>I would especially value feedback on one question: after reading the page, is the difference between on-device processing and on-Mac storage clear within the first minute?</p> showdev ai productivity swift
