Ajar makes your Mac respond to what you're doing, not what you remember to press.
Lid Angle Sync — when you lift or lower the lid, your screen brightness, keyboard backlight, and system volume adjust accordingly. Setup is a single draggable anchor on a visual curve: pick the angle where you want everything at a given level, and the rest of the ramp falls into place. External displays can join the sync too, each maintaining its own offset.
Awake — keeps your Mac from sleeping while you're in the middle of something. Built-in rules cover Claude Code, Codex, and Gemini CLI, preventing sleep only while an agent is actively working, not just because the terminal is open. Add your own rules for specific apps, Wi-Fi networks, external drives, power source, or the closed-lid clamshell setup with an external display.
