Show HN: Understudy – Teach a desktop agent by demonstrating a task once

A developer has created 'Understudy', a desktop AI agent that can learn to perform complex tasks across multiple applications (browsers, desktop apps, terminals, messaging) by watching a human demonstrate the task just once. The system records screen video and semantic events, then extracts the underlying intent to create reusable automated skills. The demo shows it learning to perform Google image searches, download photos, and edit them - essentially creating an AI that can replicate human computer workflows after a single demonstration.
