Hey everybody,

It’s not a secret AI is chaging the world. And very fast. Faster than we expect.

Lately, I’ve been fully focused on learning as much as I can about AI, started coding and just for the last months I’ve been fully focused on building agents.

So, I thought I would do this guide to help anyone that is struggling with keeping up and thinks this is too hard or rocket science.

I’m 100% sure anyone can learn these skills and they can be life changing.

This guide is for someone who has never built an agent before and may have little or no programming knowledge. And this is just the beginning.

The goal is simple:

By the end, you should understand:

  • what an agent is,

  • when to use one

  • what pieces it needs

  • how to build a first version

  • how to test it

  • how to improve it into something reliable

BEFORE STARTING: ARE YOU BUILDING AGENTS RIGHT NOW OR YOU’RE INTERESTED IN LEARNING MORE? Reply to this email and tell me what you’re building (I’m cooking something interesting).

Let’s get to work.
