The workflow gap
Your AI workflow should not stop when you close the lid
Developers start long-running AI coding tasks, the laptop sleeps, the session dies, and progress is interrupted. CloseLid solves this elegantly.
Close the lid and the machine sleeps
A normal laptop power policy can pause the workflow right when the AI agent is making progress.
Return to interrupted context
CloseLid is built to keep the right sessions alive with controlled, safety-aware activation.
