Lark, dictation that also transcribes your meetings
The dictation app I use every day, with a meeting recorder built into it. It captures your microphone and the other side of the call as two separate tracks, then hands you a speaker-separated transcript. Everything runs on your own machine.
Source only, and it needs macOS 14.2 or later on Apple silicon. There is no download, because the build is signed with a certificate only I have. You change one line and build it yourself.
