Is there something you've been meaning to do — but haven't started? NudgeDuck won't help you manage a to-do list or organize a project. It does one thing: take whatever you've been putting off, use AI to break it into one concrete step you can start in 2 minutes, and walk you through a 2-minute countdown.
