A 15-year old has found a unique way to slow the spread of cyberbullying, reports Scroll.
Trisha Prabhu has come up with an app that searches on phones and computers for words a cyberbully is likely to use.
When it spots such words, it asks if the writer really wants to send out the message.
Prabhu says 95 percent of those who receive the warning decide against sending the message out.
Her app is called Rethink and was a finalist at the 2014 Google Science Fair.
