What's great
I'm literally using Flow right now to write this comment — which I think says everything.
The "works everywhere" part is what gets me. I've tried voice dictation tools before but they always required switching to a specific app or window. Flow just… appears wherever I'm typing. That's the difference between a feature and a behavior change.
The AI cleanup is subtle but important. Speaking naturally produces run-on thoughts — Flow smooths that out without making it sound like a different person wrote it. That balance is hard to get right.
As someone who builds tools for video editors, I spend a lot of time thinking about how to reduce friction in creative workflows. Flow nails the principle: the tool should disappear, the work should remain. This is one of the rare ones that actually delivers on that.
