Trisha Prabhu, a 15-year-old high school student from Illinois, has figured out a way to stop cyberbullying before it happens.
Prabhu developed an app called ReThink that basically alerts you if a message you're about to send is potentially offensive.
"In the fall of 2013 (when I was 13 years old), I came home one day from school and read a news story about a 11-year-old girl that had jumped off the town's water tower as a result of repeated cyberbullying," Prabhu said to BuzzFeed.
ReThink is available as a free download from the Google Play store. (It will be available for Apple devices and desktops in the next couple of weeks.)
Once downloaded, the app is fairly easy to install.
The app then asks you to add it as one of your keyboards.
