Memory Notch is a recording app for the Mac that does its work without sending the conversation anywhere. It records from the notch at the top of the screen, transcribes while people are still talking, and labels who is speaking, all on the machine itself. The release installer carries the models with it, which is why it runs offline and why it weighs about 1.6 GB before you record anything.
It captures the microphone and the system audio together, so both halves of a call land in one file rather than one side of it. Each recording becomes its own folder in ~/memory holding the audio, the transcript, and a Markdown note, plus the video if screen recording was switched on. Those are ordinary files. They open in anything, they survive the app, and any tool with access to local files can read them — which is the point, because it means a recording can feed whatever comes next without an API, an export step or a format conversion.
The product keeps its job deliberately narrow, and the honest version of that is worth stating. It writes no automatic summaries. Speaker labels are numbers rather than names, and voices that overlap are hard to separate. Library search covers note titles and metadata rather than every spoken word. Each of those is a decision to leave a job to the tools the owner already has, rather than a gap waiting to be filled.
It runs on Apple Silicon Macs on macOS 26 or later. A physical notch is optional: on other displays the app appears as a capsule below the menu bar. The trial records for five minutes at a time and keeps everything captured when it stops; a one-time US$49 licence removes the limit, covers five Macs, and carries a year of updates with no subscription attached.
