Learn American Sign Language onGlobalLingo.

ASL isn't on Duolingo. It isn't on Babbel. It's here — an AI tutor that watches your hands on camera, scores every sign phoneme-by-phoneme, and slips into any role you need to rehearse before the moment you actually need it.

Why GlobalLingo, not another app

One tutor. Every language. Hands in ASL included.

GlobalLingo treats ASL as a first-class tongue, not an afterthought. The same engine that scores your Spanish /ɾ/ roll scores the handshape of your “restaurant” sign.

100+ languages in the catalog

ASL sits alongside Spanish, Mandarin, Arabic, and Swahili — no second app to install.

AI tutor with voice + camera

Signs are scored phoneme-by-phoneme against a native curve, the same engine that scores your accent.

Scenario training from lesson one

Practise the moment that matters — meeting a Deaf colleague, ordering at a signing café, a doctor's visit.

Your first lesson

Watch. Read. Sign. Converse.

Every lesson follows the same four beats — designed so the language actually sticks, even when you only have ten minutes between meetings.

The Spanish pilot at /learn/spanish shows the loop in motion. The ASL pilot ships next.

The four skills, ASL-shaped

Reading, signing, watching, mouthing.

The same four-skill scaffold that powers every GlobalLingo module — adapted for a language where the hands, not the voice, do the talking.

Reading fingerspelling
Adaptive drills ramp from two letters a second to native-speed, then layer in vocabulary.
Signing on camera
Handshape, movement, and NMM (non-manual markers) scored on every attempt — no streaks, just clarity.
Watching without sound
Train the eye, not the ear: comprehension drills streamed at the pace a real signing video moves at.
Mouthing English
Simultaneous mouthing is a real ASL skill — our tutor scores it so the mouths you do make sense, too.
