I actually got MacWhisper originally for speech to text so I could talk to my machine like a crazy person. I realized I didn't like doing that but the actual killer feature for buying it that I really enjoy is the fully local transcription of meetings, with a nice little button to start recording that pops up when you launch zoom, teams, etc. It means I can safely record meetings and encrypt them locally and keep internal notes without handing off all of that to some nebulous cloud platform.

I had previously used Hyprnote to record meetings in this way - and indeed I still use that as a backup, it's a great free option - but the meeting prompting to record and better transcription offered by Macwhisper is a much better experience.
