As an avid translator who often faces challenges with different languages when traveling across different countries. To solve my own problem, I wanted to create a simple chatbot that lets me quickly translate text from my preferred language to another, making it so much easier to communicate with other people.
Therefore, I created an AI Language Translator using the WhatsApp Sandbox mode in Twilio Programmable Messaging, Twilio Functions, Appwrite Database and OpenAI's GPT-4o API.
Demo
Watch how it works
Here is a demo video of the app:
Tech Stack
The chatbot uses Twilio Programmable Messaging (WhatsApp Sandbox) and Twilio Functions to communicate with the user.
Appwrite Database is primarily used to store the state of the user through the conversation, and all conversation data is deleted as soon as the translation is sent to the user.
OpenAI's GPT-4o API is used to translate the text to the specified language.
Steps to try
You can try it out by scanning the QR Code in the image or by texting the code join trail-has to the number +14155238886 on WhatsApp.
Once that is done, send the message Hello Twilio to begin using the chatbot.

Appwrite Database is used to store the state of the user through the conversation, and all conversation data is deleted as soon as the translation is sent to the user
OpenAI's GPT-4o API is used to translate the text to the specified language
To create this chatbot, I used OpenAI's GPT-4o API in a Twilio Function. This function consumes the text to translate, and the target language based on the user's input and returns the translated text.

Feedback, Updates, and Testimonials
During the process of developing the Twilio Function, I discovered an issue with the max length of environment variables. The issue has already been acknowledged by the Twilio team.
@anthonyjdella, I do have some product feedback. When trying out Twilio Functions, I noticed that the max length of environment variables is set to 255 characters. I was using Appwrite Databases as a part of my project, and the API keys happened to be 256 characters in length. This made it somewhat challenging to use environment variables for that purpose.
The project is getting real-world usage and positive user feedback publicly!
Are you planning to use twilio functions instead of tunneling via ngrok?
aditya has already given the open source example for a serverless function you can easily migrate it. but if you face any difficulties feel free to reach out.
Make sure to read about:
Twilio functions (Implement very basic ones first), Twilio code exchange has starter examples.
How to use the sandbox environment, and implement webhooks for a 2 way conversation have already listed on my article.
Can't wait to see what you come up with and best of luck with @twilio1 challenge.
Wonderful contribution adi :)
