Step into history with AI magic!
Dive into an immersive learning experience powered by Generative AI:
-
Learn about Generative AI technologies. If you've wanted to understand Generative AI and the potential for your applications, you're in the right place!
-
Epic Time-Travel Stories. Dive into a fun tale, chatting with icons like Leonardo da Vinci, Ada Lovelace, or Montezuma in every lesson.
-
Companion App. Interact with historical figures using Generative AI technologies (see our Responsible AI disclaimer).
Check the app directory to run the app locally or use GitHub Codespaces to run it online.
-
Accessibility FTW. Read it, hear it—audio tags bring it to life.

Getting started
Throughout this course you'll find many code examples and exercises, so we encourage you to run and experiment with the code in your own copy of this repository:
-
Select the Fork button in the upper right-hand corner of the repository or select this button:
-
Click the Code button in your forked repository, go to the Codespaces tab, and then choose Create codespace.
This will create a preconfigured online environment for you. You'll then be able to use GitHub Models to run the code examples and interact with AI models for free, without any additional setup.
Note
While GitHub Codespaces provides a quick and easy starting point you can also run the code samples locally.
Learn more about GitHub Codespaces and GitHub Models concepts here.
Lesson description
📦 Each lesson includes:
- A written lesson with an assignment and quiz.
- A short video to help further your learning.
- Solutions for each assignment and quiz.
- Characters you can interact with using our companion app, demonstrating Generative AI.
