The biggest difference is that mine is audio-first - it reads everything out over Android tts by default, and runs a computer-side parakeet + Silero VAD server for transcription (My eyes struggle with small screens, though I use it text only occasionally). It's like a voice assistant but with Claude Code. I also made a custom GUI the with shortcuts and stuff, making saying "end conversation" actually end the conversation etc.

Maybe something similar can be done with tmux still, I'm definitely going to explore it
