The gap between people who get real work out of an AI assistant and people who gave up after a fortnight is almost never technical. It is that the second group never decided what they wanted it to do. A ChatGPT course aimed at a specific job — inbox, reports, slide decks, research — closes that gap in an afternoon, while a general introduction usually leaves you back where you started.
So the useful way to shop here is by task rather than by subject.
Anything that opens with a history of large language models can be skipped. The courses that pay for themselves start with a task you recognise from your own week.

Six that each own a different corner of the problem, all in the AI course catalogue.
Deliberately broader than one assistant, which reflects how most people actually work. If your day already runs through several tools and you want them stitched together rather than replaced, start here.
The general-purpose option, built around ordinary office tasks rather than showcase demos. A good first course for someone whose job is mostly writing, summarising and organising other people's information.
Tighter and more focused on habit than breadth. It is the better pick if you have already tried an assistant, found it impressive and then quietly stopped opening it, because the failure there is routine rather than capability.
Squarely aimed at desk work — documents, spreadsheets, correspondence and the reporting cycle. The most directly applicable of the six if you work in an office and want Monday to be measurably shorter.
The craft course. It goes into how prompts are constructed and why one phrasing returns something usable and another returns waffle. Worth taking second, once you know which tasks you are trying to improve.
The most advanced of the set, covering multiple assistants, saved projects and agents that carry out longer tasks. Take this when single prompts have stopped being the bottleneck and repeatability has.
Pick one repeating task and rebuild only that. The people who report the biggest gains did not automate their job; they automated a weekly report and kept everything else the same. Narrow beats ambitious, every time.
Write your prompts down somewhere you will find them again. The single most common waste is rediscovering a phrasing you already worked out last month, and any decent prompt engineering course will push you towards keeping a library rather than starting fresh each time.
Give it your real material rather than a tidy test case. Assistants look impressive on a clean example and reveal their limits on the messy half-finished document you actually have open, which is the only version worth optimising for.
And check the output properly for the first fortnight. Confidence in the tool should be earned on your own material, not assumed from a demo, and the habit of reading before sending is what keeps this useful rather than embarrassing.
Buy for the task, not the topic. An office-productivity course finished and applied to one process will do more than a masterclass watched at double speed, and the advanced material only makes sense once you have something repeatable to advance. Start with the job that annoys you most on a Monday and work backwards from there into the office AI course that addresses it.
Each of these runs on Udemy, and enrolling takes a couple of minutes from the AI productivity course listings.
