No. As of November 2026, Duolingo does not offer American Sign Language (ASL), British Sign Language (BSL), or any other sign language. Every course in its catalog teaches a spoken or written language. If you want Duolingo-style learning for ASL, with short daily lessons, a path, and streaks, you need an app built for signing.
Why doesn't Duolingo teach ASL?
Duolingo's lessons are built around reading, typing, listening, and speaking. Sign languages are visual: handshape, movement, location, and facial expression all carry meaning at the same time. There is nothing to type, so teaching ASL well takes clear video of real signers and a different kind of lesson.
A Duolingo team member explained in February 2026 that the platform is designed around reading, writing, listening, and typing, and that teaching sign languages well would need high-quality video and feedback on physical signing, which goes beyond its current course format. They also pointed out that there isn't just one sign language: ASL, BSL, Mexican Sign Language, and many others are distinct languages, so launching only one or two would leave many communities out.
Will Duolingo add ASL?
Duolingo hasn't announced a sign language course or a timeline, even though learners have asked for years.
