Creating a Basic Chatbot

Let’s walk through the basic structure of a chatbot that leverages both Ollama & Twilio. This chatbot will be simple but effective, providing users with automated responses.

Step 1: Set Up Your Environment

You’ll want to create a Python virtual environment for your project. In your terminal, run:

bash
mkdir my_chatbot
cd my_chatbot
python -m venv venv
source venv/bin/activate  # On Windows use: venv\Scripts\activate

Then, install the required libraries:

1
2

bash
pip install twilio flask requests

Step 2: Coding the Chatbot

You’ll want to create a file called

app.py

in your project folder. Below is a basic structure for your chatbot: ```python from flask import Flask, request from twilio.twiml.messaging_response import MessagingResponse import requests

app = Flask(name)

@app.route('/sms', methods=['POST']) def sms_reply(): incoming_msg = request.form['Body'] # grab the incoming message body response = requests.post('http://localhost:11434/api/generate', json={ 'model': 'llama2', 'prompt': incoming_msg }) answer = response.json()['response'] msg = MessagingResponse() msg.message(answer) return str(msg)

if name == 'main': app.run(debug=True) ``` This code sets up a Flask web server that listens for incoming SMS messages. When a message is received:

It forwards that message to the Ollama model for processing.
It then responds back to the user via SMS.

Step 3: Run Your Bot

You can run your chatbot locally by executing:

1
2

bash
python app.py

Now your chatbot is listening! But you need to set up ngrok to expose your local server to the internet so Twilio can interact with it.

Step 4: Set Up Ngrok

Run the following command in a new terminal window:

1
2

bash
ngrok http 5000

Copy the HTTPS URL generated by ngrok, as you will need it in your Twilio settings.

Step 5: Configure Twilio

Go back to your Twilio console & navigate to your phone number settings. Under the Messaging section, paste the ngrok URL followed by

/sms

in the A Message Comes In section. This configures Twilio to send all incoming messages to your bot's Flask server.

Tips for Enhancing Your Chatbot

Train Your Model: Utilize various datasets for better responses. This can be feedback from user conversations.
Integrate Persistence: Store conversation history for context. This can be achieved with a simple database.
Improve Engagement: Utilize Twilio’s features to send media or rich content to keep users engaged!
Test, Test, Test: Continually refine your chatbot. Analyze user interactions & update responses accordingly.
