Chat Bots Help Texans Stop Smoking

Quitxt is a bilingual texting program designed to help people stop smoking.

What if your phone could help you quit smoking or lose weight? That’s the idea behind a new texting service created by San Antonio medical professionals and engineers. It's a new way to use your mobile device to improve your health.

A voice on a video says "quitting smoking is the best and most life-saving decision that you can make." That’s the greeting from a new automated messaging system called Quitxt, a program developed by UT Health San Antonio and University of Texas at San Antonio engineers to help smokers kick the habit.


"The chat bot is quite, let’s say, intelligent to talk to humans. It’s gradually evolving to become sort of human," said UTSA electrical and computer engineer David Akopian, Ph.D.

A chat bot is a computer program that conducts a conversation with you, in this case, by text on your phone. It’s not a real person on the other end. But questions and answers are programmed by health professionals.

The biggest challenge with chat bots, according to post-doctoral student Sahak Kaghyan, is setting up those multi-stage conversations that may go on for months at a time to help someone quit smoking.

"You need to be able to follow up the next question or the next answer," he said.

Quitxt is bilingual, able to ask and answer in English or Spanish.

"We decided why not start with Spanish and later on maybe extend this to other languages: French, German, Russian," Kaghyan added.

It’s a health tool many younger people will embrace, according to engineering doctoral student Devasena Inupakutika. "It’s a cool technology," she commented. "Young people usually go for cool things which are very fast and immediately they’ll get the results."

While the chat bot to help smokers quit is up and running, engineers are working on other health applications for this technology, like one specifically for breast cancer patients. The program answers questions like a virtual nurse.

"If they’re having some issues, instead of going all the way to the clinic or hospital, they can just open up their app and then see if that can help them," explained masters student Chetan Basutkar.

This project was funded by the Cancer Prevention and Research Institute of Texas, part of three billion dollars Texas voters approved in 2007.

Akopian says so far, more than 2000 people have signed up for Quitxt at no cost. "It is free and we are planning to keep it that way," he stated.

The professor believes thousands of Texas’ three million smokers could quit, by using this guided communication. To enroll, all you have to do is text 'Iquit' to 57682.
