What is Whisper Flow and how does it help with prompting AI tools?

Whisper Flow is a dictation tool where you hold down two keys on your keyboard and talk, and it transcribes what you say — including correct punctuation, bullet lists, and paragraph breaks — without needing to say 'period' or 'exclamation mark' explicitly (though you still can). It's described as much more accurate than built-in options like the iPhone's voice-to-text. The benefit for AI prompting is that you can ramble through a lot of context and detail much faster by talking than by typing, which makes it easier to give Claude the depth of information needed for a good response. It's free, though heavy use can trigger a message to wait for it to refresh.
