Can somebody help me understand how they use these, I feel like I'm missing something or I'm bad at something?

I only spent 10 minutes with Handy, and a similar amount of time with SuperWhisper, so pretty ignorant. I tried it both with composing this comment, and in a programming session with Codex. I was slightly frustrated to not be hands free, instead of typing, my hands were having to press and release a talk button (option-space in handy, right-command in superwhisper), but then I couldn't submit, so I still had to click enter with Codex.

Additionally, for composing this message, I'm using the keyboard a ton because there's no way I can find to correct text I've typed. Do other people get really reliable and don't need backspace anymore? Or.... what text do you not care enough to edit? Notes maybe?

My point of comparison is using Dragon like 15 years ago. TBH, while the recognition is better (much better) on handy/superwhisper, everything else felt MUCH worse. With dragon, you are (were?) totally hands free, you see text as you say it, and you could edit text really easily vocally when it made a mistake (which it did a fair bit, admittedly). And you could press enter and pretty functionally navigate w/o a keyboard too.

Its weird to see all these apps, and they all have the same limitations?
