How to Use AI

Start Here

A short ladder of real tasks. Each rung is something you do in whatever tool you already have open, and each one leaves you a little better at using AI on your own work.

This isn't a course you finish and file away. It's a handful of small wins, done one at a time on the things you already care about: a paper, a job search, a lesson plan, a side project, the admin that eats your evenings. By the time you've climbed a few rungs, using AI well will just be something you do.

Two promises before we start. You can begin completely free, no subscription, no card, not yet. And you're not going to fake your way through this: the first thing we build is real understanding, not button-clicking.

The reframe: read this before anything else

You are not "studying to become an AI expert." That framing makes anyone feel like a fraud. Here's the true version instead: you are using AI on your own real work. That's the whole job right now.

Once it visibly works for you, once the first draft writes itself and the thing you were dreading takes ten minutes instead of an hour, you'll understand these tools better than almost everyone around you. Not because you memorized anything, but because you used them on something that mattered to you.

No calendar, no guilt

Life is unpredictable, so nothing here runs on weeks or deadlines. Every step below ends the same way: you're done when a specific thing exists. Not "by Friday." Not "in three weeks." When the thing exists, you've cleared the rung.

That means a busy month where you touch none of this costs you nothing. The ladder waits. There is no behind to fall.


First: understand how it actually works (free)

Before any setup, spend a little time just understanding what AI is. Not to become technical, but to become the person who knows what these tools are doing instead of poking at them and hoping. That understanding is what turns "I use ChatGPT sometimes" into real, transferable skill.

The good news: the best explanations in the world are free videos, and you can play them in the background while you do something else. No subscription, no notes, no homework. Just let them wash over you a few times. Here's the short list, easiest first.

Watch and listen, free, in this order

Start visual and short (3Blue1Brown). Calm, animated explanations:

Then go deeper (Andrej Karpathy). Longer and plainer-spoken, good background listening:

  • Deep Dive into LLMs, the big one. If you only half-absorb it the first time, that's fine. Play it again another day.
  • How I Use LLMs, practical: how someone fluent works with these tools day to day.

Want a fuller visual series to keep going? This playlist walks through the ideas step by step.

You don't have to finish all of these before starting the hands-on steps below. Do both at once: understanding grows in the background while your hands learn the tools. But don't skip it. The understanding is what makes the skill real.


What's free and what costs money

You can go a long way without paying a cent, so start there and only pay once it's clearly earning its keep.

Free vs. paid: the honest version

Free, start today: all the understanding videos above; ChatGPT, Claude, and Gemini all have a free tier; and Google's NotebookLM is free with a Google account. That's enough for Milestones 0, 1, and 2.

Paid, for later: the paid tier of any of the three (roughly $20/month as of writing) gets you the better models, higher limits, and the coding-agent step in Milestone 3. Don't pay yet. You'll know it's time when the free tools are already saving you real hours. At that point the subscription pays for itself in a week.

The first few rungs are deliberately easy, free, and pressure-free: just "look what you can already do." Start there.

The four rungs of the ladder Four steps rising left to right: a quick win, load your work in, live in it, build a real thing. The first three are free; the last is the paid step. Quick win 0 Load yourwork in 1 Live in it 2 Build areal thing 3 free paid done when it exists
Each rung ends when a specific thing exists, not on a date. The first three are free. Only the last needs a paid plan.

Where this can go next (optional)

Those four rungs are the whole path. Climb them and you're good at this, better than almost everyone who only ever chats. Everything past here is an optional branch, taken only if it pulls you in:

One last thing

Notice how you got here. Not by memorizing jargon, but by understanding the tools and using them, one real task at a time, each one leaving you a little more fluent. That's why it can't be faked: you understand what you're doing because you did it on something that mattered to you.

And if life gets loud and you don't touch this for a month, that's allowed. The ladder is built out of "you're done when," not out of dates. It'll be right here when the next quiet hour shows up.

The one thing to remember

You're not learning AI in the abstract. You're using it on your own real work right now, for free, to start, and every rung you clear leaves a real thing behind. Do the next rung. Nothing more.
