TypeScript AI Dapp tutorial

This tutorial guides developers through building a decentralized AI Assistant using the Internet Computer Protocol (ICP) and integrating it with the OpenAI API.


Learning Objectives

By the end of this tutorial, learners will be able to:

  1. Understand the architecture of a decentralized AI chatbot.
  2. Configure and deploy a chatbot on the Internet Computer Protocol.
  3. Integrate OpenAI API for AI-driven chat functionalities.
  4. Manage and secure sensitive credentials in a decentralized application.

Tech Stack

Here are the technologies we will be using in this tutorial:

  • Internet Computer Protocol (ICP): The core platform for deploying the chatbot, providing a decentralized infrastructure.
  • JavaScript/TypeScript: Used for the development of the chatbot, leveraging modern web development practices.
  • Node.js: The runtime environment for executing the JavaScript code outside of a browser.
  • DFINITY Canister SDK: A toolkit for building and deploying applications on the Internet Computer.
  • Internet Identity: A decentralized identity management system for the Internet Computer.
  • OpenAI API: Utilized for AI functionalities within the chatbot.


  • Basic understanding of JavaScript and TypeScript.
  • Familiarity with Node.js and its ecosystem.
  • Knowledge of decentralized applications (DApps) is beneficial but not necessary.
  • Access to OpenAI API credentials.
