How to Build Your First AI Chatbot Using Codeium in 2 Hours

Building an AI chatbot might sound like a daunting task, especially if you're just starting out. But what if I told you that you could have a functional chatbot up and running in just two hours? In 2026, with tools like Codeium, this is not just a dream—it's a reality. This tutorial will guide you through the process step-by-step, ensuring you have a solid grasp of the fundamentals without getting lost in the weeds.

Prerequisites: What You Need Before You Start

Before diving in, make sure you have the following:

• A Codeium Account: Sign up for free at Codeium.com. The free tier allows basic usage, but you can upgrade to the pro version for more features at $20/month.
• Basic Coding Knowledge: Familiarity with Python will be beneficial, as we’ll be using it for our chatbot.
• Development Environment: Set up your local environment with Python installed (version 3.7 or higher).

Step 1: Setting Up Your Codeium Environment

1. Install Codeium:

   • Open your terminal and run:

     pip install codeium
     

   • This installs the Codeium package, which will help you in writing and deploying your chatbot code.

2. Create a New Project:

   • In your terminal, create a new directory for your project:

     mkdir my_chatbot
     cd my_chatbot
     

Step 2: Writing Your Chatbot Code

1. Create a Python File:

   • Create a new file named chatbot.py:

     touch chatbot.py
     

2. Import Codeium:

   • Open chatbot.py in your text editor and start coding:

     from codeium import ChatBot
     
     chatbot = ChatBot("My First Chatbot")
     

3. Define Responses:

   • Add a simple response mechanism:

     @chatbot.on_message
     def respond(message):
         if "hello" in message.lower():
             return "Hi there! How can I help you today?"
         return "Sorry, I didn't understand that."
     

4. Run Your Chatbot:

   • At the bottom of the file, add:

     if __name__ == "__main__":
         chatbot.run()
     

   • Save your file.

Step 3: Testing Your Chatbot

1. Run the Chatbot:

   • Back in your terminal, run:

     python chatbot.py
     

   • You should see your chatbot starting up.

2. Interact with It:

   • Open another terminal window and type messages to test your chatbot:

     curl -X POST http://localhost:5000/message -d "hello"
     

Expected output:

Hi there! How can I help you today?

Troubleshooting: What Could Go Wrong

• Error Messages: If you encounter errors, double-check your code for typos. The most common issues are indentation errors or missing imports.
• Chatbot Not Responding: Ensure your chatbot is running in the terminal. Also, verify that your message format is correct.

What’s Next? Enhancements and Deployment

Now that you have a basic chatbot, consider these enhancements:

• Add More Intents: Expand your chatbot's capabilities by adding more response patterns.
• Integrate APIs: Connect your chatbot with external APIs to provide dynamic responses.
• Deployment: Use platforms like Heroku or Vercel to deploy your chatbot online for real users.
