Everyone dreams about making the next cool AI tool and doesn't bother checking if someone has already made the same thing years ago without the word "AI" in the description

In order to get the same behavior with Amphetamine you’ll need to: 1. Install it from the AppStore (no brew, no GitHub) 2. Not forget to enable lock on lid close 3. If you ever connect/disconnect power while the lid is closed without the optional “Power Protect” system, the MacBook will sleep. The system is a script and a configuration file making sudo pmset -a disablesleep passwordless. 4. Add hooks to Claude Code configuration that will use Apple Script to start and stop Amphetamine sessions. For Codex you’ll have to make a script that will watch process activity to know when a turn ends.

It’s not like Amphetamine can’t do the same, it’s that this app is made specifically for AI agents and nothing else.
