SetupOne message, once per chat

Tested onThe Art of War, chapter 3

Checked on 15 Oct 2026. Tools change fast, so the official page always wins if it says something different.

Step by step

Paste the setup prompt

Start a new chat and paste this first. ChatGPT replies "Ready" and now knows the codes for this chat.

Setup prompt

In this chat I'll use short codes. When I paste some text and type a code, do this:
/mindmap: a map of the key ideas and how they connect.
/flashcards: question-and-answer cards I can test myself with.
/sketchnotes: a one-page visual summary.
/comic: the hardest idea as a short comic, panel by panel.
Reply "Ready" when you understand.

Paste a chapter

Use text you're allowed to use. We tested it on chapter 3 of The Art of War, a public-domain translation.

Type a code

Start with /mindmap. Then try /flashcards to test yourself. In our test it made 6 flashcards.

/mindmap

Pictures need a login

/sketchnotes and /comic can come back as text: a one-page layout, or a comic script panel by panel. Logged out, ChatGPT asked us to log in before it would draw images.

Make the codes stick

In a logged-out chat the codes only last for that chat. To keep them, save the setup in Settings → Personalization → Custom instructions (you need an account).

The catch

They aren't secret commands. ChatGPT only follows them because you set them up.
Image versions use your image limits on the free plan.
A summary isn't the whole book. Use it to get the key ideas and test yourself, then read the parts that matter.
