This technique will improve your writing, brainstorming and more

Hey Warrior

Today I’ll show you a really useful prompting technique that you can use to fine-tune your AI outputs.

I call it the LEVER technique, and it’s one of my favorite prompts.

Here’s what we’ll cover:

  • Why you should use the lever technique

  • When and how to use it

🤖 Why you should use the lever technique

Very often when you’re using ChatGPT (or any other LLM) you’ll find yourself in a situation where the output doesn’t fully match your expectations.

For example, I recently asked ChatGPT to write me “a short cold email pitching my ‘chatgpt prompt improvement’ service”.

But it gave me an email that sounded too professional:

Now I might follow up with a prompt and say: “Can you make this email sound less professional?”.

But then ChatGPT swings too much in the other direction, making this email sound too casual:

So what do you do in this case?

Here’s where the LEVER technique comes into play.

🧠 How do you use the LEVER technique?

The lever technique is a smart way that allows you to make adjustments to your AI outputs in a more fine-tuned way.

Essentially, it gets ChatGPT (or another LLM) to first evaluate its own output and quantify it.

With the quantified output, you can then adjust it very precisely according to your needs.

Here’s how it works:

  1. You ask ChatGPT to rate its output on a scale of 1-10. You also define the scale, f.e. 1 is very casual, 10 is very professional.

  2. ChatGPT will give you the answer (f.e. a 6/10)

  3. You then adjust it to your desired number (f.e. a 3/10)

Let me show you how to use this on the example from above:

And this instantly gave me an email that sounded a lot more like how I wanted it to.

(Don’t worry, I’ll run through some more examples below).

Here is the LEVER prompt template so you can easily copy and paste it:

"On a scale of 1-10.

If 1 is a ...

And 10 is a ...

How would you rate this ...?"

Ok, so far so good.

But now you might ask, why not just use this technique in the initial prompt? Something like this…

It does help slightly to do it this way, but I’ve noticed that letting the AI first evaluate its own output and then readjusting it, works so much better.

I guess it’s because the AI then has a better point of reference to fulfil your request.

💡 Three examples of the LEVER prompt in action

The lever technique can be used for anything really. Let’s walk through a couple more examples.

  1. Adjusting the writing style ✍️ 

When ChatGPT writes something, it usually uses a very formal tone by default.

Here I told it to write another email:

I then plugged in my lever prompt and told chatGPT to rate its output on the scale:


After this, the email became the perfect amount of casual:


  1. Creativity in brainstorming 🧠 

Here I used the lever technique to make ChatGPT more creative in brainstorming.

I started with a simple prompt and the output was pretty standard:


Then I used the lever technique…

And voila! ChatGPT cranked up creativity and gave me much more unique ideas.

  1. Image generation 🖼️ 

You can use this technique for image generation as well.

In this example, I asked ChatGPT for an image of two dogs fighting. Here’s what it came up with:

Then I used the lever technique…

(For images, ChatGPT protests that it is not ‘human’ enough to rate creativity, but that last line in the prompt will get it to do it anyway.)

I first told it to generate a 2/10, making it an even blander image:

Then I told it to generate a 10/10… here’s what it produced:

I think it’s fair to say that this was more creative.
