PinW/whisper-key-local ? reverse-engineered prompt

Build me a small desktop app that lets me press a global hotkey, talk into my microphone, and have the speech transcribed straight into whatever app my cursor is in.

It should work locally on my computer, not send audio to the cloud, and it should support both Windows and macOS. I want it to start recording from anywhere, then stop and paste the text automatically, with an option to also press Enter after pasting. If possible, let me switch between clipboard only and direct typing, and give me a tray or menu bar icon where I can change the model, audio device, and a few basic settings.

I also want a simple voice command mode so I can say trigger phrases like undo or open notepad and have it run a shortcut, insert a snippet, or launch a command. Use current docs online if you need to, and make it feel polished and easy to use.
