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 creates an online environment for the code examples. Continue with the course setup guide to create a Microsoft Foundry project, deploy a chat model, and configure your endpoint and API key.

[!NOTE]

While GitHub Codespaces provides a quick and easy starting point you can also run the code samples locally.

Both local development and Codespaces require model configuration. The course setup guide covers Microsoft Foundry, the repository-root .env, and a live companion app check.

The packages in the repository root and the companion app require Node.js LTS. Each lesson package has its own requirements.

Lesson description

📦 Each lesson includes:

A written lesson with an assignment and quiz.
Solutions for each assignment and quiz.
Characters you can interact with using our companion app, demonstrating Generative AI.
