Imagine having a language tutor who was always on, available anytime to teach you new vocabulary or check up on your progress.

(CNN)– A new AI platform aims to make learning sign language easier. Nvidia has launched the free platform called signs. It features a 3D avatar to demonstrate signs. Users keep their video cameras on while interacting with the platform, and an AI tool provides feedback as users practice.

Nvidia on Thursday launched Signs, a free AI-powered tool that helps teach American Sign Language. Why it matters: Although ASL is the third most commonly used language in the United States, there are far fewer tools available for learning it than for spoken languages.
