Lesson 7 of 8 · about 8 minutes

Making It Yours

The third time you type the same instructions from scratch, you will wish you had saved the first one. So save the first one.

The idea

Anything you ask for more than once should be written down once and reused. That is the whole lesson. The rest of this page is where to put it, and what it costs to keep going.

The recipe card box

You already own this system. Somewhere in your kitchen is a box of cards, and every card is a thing that worked, written down so you never have to work it out again. You do not re-derive the pie crust every Thanksgiving. You pull the card.

Do that with instructions. When a set of instructions produces something good, save it — the whole thing, exactly as you typed it, including the background and the example. The example is the part people leave out, and it is the part doing most of the work.

Two kinds of card are worth keeping.

Where to keep them

  1. A note on your phone. There is nothing wrong with this and no reason to be embarrassed by it. Copy and paste at the start of a conversation. It works with every assistant and needs nothing new from you.
  2. A document on your computer. Same idea, more room, and you can search it.
  3. The assistant’s own memory. Every major assistant has somewhere to keep standing instructions so you do not have to paste them each time. The names differ — you may see custom instructions, personalization, projects, gems, or memory. Look in settings. Paste your standing card in once, and it applies to every conversation afterwards.

Start with the note on your phone. Move to the built-in memory once you know which instructions have earned their place.

What this costs, in plain dollars

Free versions of all four assistants are genuinely useful, and everything in this course was written to work on one. What free usually means in practice: a limit on how much you can send in a day, and a slightly less capable version of the assistant when the service is busy.

Paid personal plans for the well-known assistants have settled at roughly twenty dollars a month, as of August 2026. Prices move and offers change, so check the number on their own site before you sign up rather than trusting this page.

What the money buys, in practice:

When paying is worth it, and when it is not

Worth it if any of these are true:

Not worth it if:

Two practical notes. You do not need more than one paid plan — paying for two assistants at once is a common and avoidable waste. And you can cancel from the same settings page you signed up on, at any time, and carry on with the free version.

Try it now

About nine minutes. Works on a phone.

  1. Open a note on your phone or a document on your computer. Title it “AI cards.”
  2. Write your standing card: who you are, who you write for, how you like things written, and the line “If you need something from me, ask before you guess.”
  3. Go back to your best set of instructions so far — most likely the project from lesson 4 — and paste the whole brief in as your first job card. Give it a name you will recognize in six months.
  4. Open your assistant’s settings and look for custom instructions, personalization, or memory. If you find it, paste your standing card in and save it.
  5. Start a new conversation and ask for something small. See whether what comes back sounds more like you than it did last week.

If it goes sideways: if your assistant has no setting for custom instructions, nothing is lost. Keep the card in your note and paste it at the top of a conversation when you need it. That works in every assistant, and it is all the setting was doing for you anyway.

Plain-English recap

  • Anything you ask for twice should be written down once. Keep a card box.
  • Keep one standing card about you, and one job card per recurring chore.
  • Free is genuinely enough for most people. Paid runs about twenty dollars a month and earns its keep when it saves you an hour.

Next: noticing when your assistant changes — because it will.
