If you’re one of the millions of people who use Snapchat, you might want to think again

Snapchat is launching a new lens that can help you learn American sign language (ASL). It’s called ASL alphabet lens, and it’s in partnership with signall, a company that has built technology that can translate sign language.

The lens should open in Snapchat if you have the app on your phone. It offers a tool to help you fingerspell words and help you memorize which handshapes are which letter.
