41 ChatGPT commands

Commands for ChatGPT. The /name is just a memorable label — what ChatGPT understands is the description. Register the custom instructions below once, and from then on typing /truth alone works.

Register the custom instructions once, done

Go to ChatGPT Settings → Custom Instructions and paste the full text below. After that, just type /truth or /no fluff in chat. No name collisions with the image prompt set, so they can live together.

When I type something starting with /, read it as defined below and act immediately. Don't ask what it means; answer ordinary questions normally. If I chain several (/truth /no fluff), apply them in the order written.

4 study commands — in order, they finish a topic

Skim with Cheat Sheet → frame it with Blueprint → memorize with Flashcards → wrap up with Mind Map.

  1. 01

    Cheat sheet

    Compresses one topic onto one page — key concepts, important formulas and term definitions as lists. Use it first when you need a fast sweep, like the night before an exam.

    Cheat Sheet: supervised classification. College freshman level. For Friday's exam

    Add your level (middle school/college freshman) and goal (exam/interview prep) and it meets you at eye level.

  2. 02

    Blueprint

    Takes the topic apart and shows, on one page, what to learn in what order and how the concepts connect — beginner through advanced.

    Blueprint: supervised classification

    Use it after the cheat sheet, and the pieces you just skimmed snap into place.

  3. 03

    Flashcards

    Turns the topic into a deck — question on the front, answer on the back. You pick the count, and you can quiz yourself right after.

    Flashcards: supervised classification, 20 cards

    Once the cards appear, follow with "Quiz me one card at a time. Take my answer first, then grade it" — that's when it actually sticks. Reading alone doesn't.

  4. 04

    Mind map

    Draws a hierarchy branching out from the central topic. The whole picture in one glance — great for wrapping up.

    Mind Map: supervised classification

    After studying, draw it yourself on blank paper and compare — the gaps reveal themselves.
