How to Use AI

Pick a Tool

There are three big AI chat tools, they are all very good, and the honest truth is that the one you already use is a fine choice. This page helps you decide without pretending there's a single right answer.

If you came here expecting to be told which tool to buy, here's the part nobody selling you a course wants to say out loud: the three main tools, ChatGPT, Claude, and Gemini, are much closer to each other than the arguments online suggest. They can all write, summarize, explain, brainstorm, read your files, and search the web. Any of them will handle nearly everything in this guide. The gaps between them are real but small, and they close a little more with every update.

So the most useful thing to know first is this: the skills transfer. Everything you learn about grounding, prompting, and building a project works the same way in all three. If you already have a habit, you open ChatGPT without thinking about it, that habit is a good reason to stay put. Switching tools to chase a small advantage usually costs you more in lost familiarity than you get back.

The point of this page

Not to crown a winner, but to give you a fair picture of each tool, a plain comparison table, and a simple rule for choosing, so you can pick one, stop second-guessing, and get on with learning.

1. Three honest character sketches

Think of these as three capable people with slightly different temperaments, not as a ranking.

ChatGPT, made by OpenAI, is the default: the one most people mean when they say "AI." It has the biggest ecosystem, the most add-ons, the most tutorials written about it, and a feature called Custom GPTs, which are little pre-set versions of ChatGPT you (or other people) can build and share for a specific job. It also has strong image generation and a well-regarded voice mode. If you only ever learn one tool, there's nothing wrong with this being it.

Claude, made by Anthropic, is the one people reach for when the thinking has to be careful. It's known for long, patient reasoning and for writing that sounds a little less like a machine, less of the "I'd be delighted to assist" flavour. It has Projects (a saved workspace, covered later in this guide) and a set of coding tools that are among the best around. If you write a lot, or you want an answer worked through slowly rather than fired back fast, Claude tends to suit.

Gemini, made by Google, has one advantage the others structurally can't match: it lives inside Google. If your life is already in Gmail, Google Docs, and Drive, Gemini can reach into them directly. It also comes with a different companion tool called NotebookLM, which you hand a pile of documents, and it answers only from those, citing the exact sentence each answer came from. Nothing ChatGPT or Claude offers is quite like NotebookLM, and it's free.

2. The same tools, side by side

Here is the comparison in one place. Everything below is approximate and moves around, so treat it as the shape of things, not a spec sheet. Prices and model names change; the columns are here so you can see the pattern, not memorize numbers.

Weakest at Settings that shift often; can sound generic Smaller ecosystem; no image generation Uneven polish; features spread across products
One idea, three names

This trips everyone up, so learn it once. A saved workspace (a place where you park your files and instructions so you don't re-explain yourself every time) has a different name in each tool. ChatGPT calls it a Custom GPT (and now also has a Project). Claude calls it a Project. Gemini's closest thing is a Gem, and its companion tool NotebookLM calls it a notebook.

The rest of this site just says "project" and means all of them. When you read "make a project," do it in whichever tool you picked, under whatever that tool calls it.

3. Same room, three front doors

The picture to hold in your head: the tools are three doors into the same room. The room is where the useful work happens: grounding, prompting, checking. Which door you walk through barely matters. What matters is that you go in.

Same ideas, three front doors. The tool is how you get in; the skills are what you do once you're inside, and they're identical.

4. So which should you pick?

No winner is coming, because there isn't one. Instead, a decision rule you can actually follow:

That's it. Pick one, follow its setup page next, and come back to try another once the first feels easy. This guide has a setup walkthrough for each: ChatGPT, Claude, and Gemini. Start with whichever you chose.

Quick check

You already pay for ChatGPT and use it every day. A friend says Claude writes more naturally. What's the sensible move?

Answer: the tool you already pay for and know how to use is almost always the right one to keep using. The differences between the three are small, and everything you learn carries over, so switching to chase a minor edge usually costs more than it gives.

If you're curious about another tool, its free tier is right there. No need to burn your working habit to find out.
