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.

The platform is called Signs, a teaching platform developed in partnership with Nvidia, the American Society for Deaf Children and the creative agency Hello Monday. It’s an interactive web platform that uses a camera to give AI-enabled feedback and 3D avatar with voice to teach sign language.
