I wanted to build a shell. I built a PTY proxy instead.

I spend 8+ hours a day in a terminal. Mostly running Claude Code, reviewing its output, copying bits of it, searching for "that error from 20 minutes ago." The experience is terrible. Scrolling up through 2000 lines of AI output in tmux. Entering copy mode, carefully selecting text with arrow keys, accidentally losing the selection, starting over. Searching scrollback with Ctrl+R and finding the wrong thing. Giving up and re-running the command. In 2026, we have AI writing entire codebases, and I'm still grep-ing scrollback with my eyes like it's a VT100 in 1978.
