How to not prompt.

But use the Prompt Maker instead.

You know ChatGPT is as good as the input ( = the prompt).

But why should you care about knowing how to prompt?

Shouldn’t you just… ask ChatGPT to prompt better?

Yes & no. You have two options.

1. Use my free GPT “Prompt Maker” inside ChatGPT.

   1. It has over 700,000+ users to convert bad prompt into good ones.

   2. I will show you in this newsletter exactly how to best use it.

   3. I just updated it today for this newsletter :)

2. Or you will learn prompt engineering yourself.

   1. Chain-of-Thought prompting.

   2. Zero vs. Few-shot prompting.

   3. Role - Ask - Steps - Example(s) - Iteration.

   4. …

If you already subscribed to Ruben Hassid (my Substack), you will eventually master all of the above. But let’s focus today on my free “Prompt Maker”.

How can I use it?

1. Go to ChatGPT > on the left menu > click on “GPTs”.

2. Or click on this: https://chatgpt.com/g/g-hhh4w3eov-prompt-maker.

3. You will see this menu (which is known as a “GPT” or custom ChatGPT):

   

If you click on the top left, you can see people’s reviews on it (click “About”):

Let’s start using it now.

From a bad to a good prompt

Example #1: Linkedin hooks

I prompted: “A prompt to write drastically different hooks for a Linkedin post I share.” Here’s my Prompt Maker’s answer:

Is it the best prompt possible for such task? No.

Is it a fantastic start from a one-liner terrible prompt? The best you could have.

Now you only have to copy it & paste it on a new ChatGPT chat.

I made the Prompt Maker so it always creates a “Copy” button at the top right.

When copying & pasting, be careful with the green text: it says “Insert Linkedin post here” so it’s up to you to insert it the right way. To do so, I write this:

/// what I’m about to share ///

[WHAT I SHARE]

/// what I’m about to share ///

I picked a random Linkedin post, paste it there, and chose the model (top left) o3.

You end up with this monstrous prompt… but it’s actually only 2 steps:

1. From your bad prompt → to the Prompt Maker → to a better prompt to copy.

2. Paste it on a new ChatGPT chat → paste your own Linkedin post → choose the model o3 (at the top left).

That’s it. And that’s the results:

You want a different twist? Select another model to write (GPT-4.5 is also good).

Pro tip: Use Claude-Opus 4 + Extended thinking.

Example #2: Newsletter

I input: “A prompt to read my last 3 newsletters I input to search the web & give me ideas for new topics.”

Copied it & pasted it with the model “o3”:

ChatGPT asked me for my paste newsletters, and I pasted it.

The answer actually blew me away.

It’s so long & detailed & on point I can’t screenshot the whole thing.

Instead, I created a link from my conversation so you can have a look:
