Two people ask the same assistant the same question and get the same flat answer. One of them then spends ten minutes setting it up properly and never gets a generic answer again. The difference is not a better prompt — it is personalization, and it is a skill with four specific levers.
This course takes personalization apart. You will learn what an assistant actually knows about you (far less than it seems), how to tell it who you are in a way that survives every new chat, how memory and projects and uploaded documents change what it can do, and how to teach it your voice by showing rather than telling.
Then the part almost everyone skips: checking whether any of it worked. You will build a small personal test set, compare answers with and without your setup, and learn to spot the two failure modes personalization creates — stale context that quietly misleads, and an assistant so tuned to you that it stops disagreeing with you.
