Out of curiosity, why do you use `claude -p` for that over remote control? I use that for similar work.
Maybe something similar can be done with tmux still, I'm definitely going to explore it
I use on-device STT with Claude Code's built-in remote control feature to do what you do without needing claude -p, but I guess I don't use it for large enough quantities of text where on-device STT quality becomes a big issue.
The STT on Gboard is very solid, so if that covers your use case you're good!
