Prompt Engineering Guide

A free guide to writing better instructions for AI chatbots, from basics to advanced methods.

What it does

"Prompt engineering" means learning how to word your requests to an AI model so you get better answers. This guide collects lessons, examples, research papers and tools on the topic.

It starts with the basics, such as what a prompt is made of and general tips, then moves on to named techniques like giving examples, asking the AI to reason step by step, and connecting the AI to outside documents. It also covers uses such as generating code or data.

The guide is available as a website in many languages. The same team also sells paid courses, which are separate from this free material.

Who it's for

Anyone who uses AI chatbots and wants better results, plus developers building with AI models.

Can I use it without coding?

Yes. You can read it all on the website. Some notebooks need Python if you want to run the examples. New to this? Start here.
