证据

Last week I built The Hitchhiker's Guide: an iPad home-screen app with a big friendly DON'T PANIC on it. Tap it, pick a character, chat. Every answer comes from AIs on my own PC: Claude, free cloud AIs, and local models on my one graphics card.

来源

Status strip: CPU and GPU temps, memory, when the last backup finished, and whether the internet is up. It goes red only when something is actually wrong.

来源

PC buttons: exactly four. Back up now. Put the local AIs to sleep (frees the graphics card). Lock the PC. Say something out loud on the PC speakers.

来源

Three Claude helpers, talk-only: a planner, a Linux tutor, and a notes keeper. From the iPad they can talk and read. They can't run commands, edit files or browse.

来源

Keeps the PC awake while I'm using it, so the PC doesn't nod off mid-conversation. The screen still locks.

来源

Security pass: I had it reviewed. The big fix: chat text now goes to Claude through the front door (stdin), never on the command line, so a sneaky message can't pretend to be a setting.
