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

Understudy revolutionizes desktop automation by letting users teach an agent from a single task demonstration, eliminating the need for scripting. In testing, the agent successfully replicated a 47‑step data‑entry workflow after just one human demonstration, a data point that highlights its efficiency. This zero‑code approach is faster than the average automation tool, which typically requires 20‑30 minutes of setup for comparable tasks. By learning from natural cursor and keystroke patterns, Understudy reduces the barrier to automation far below what #9's static BBS photo can offer in terms of active utility.
