Every ASL letter, on a hand you can turn around.
A picture of a handshape shows you one angle. This is the real thing: a rigged avatar forming each letter of the American manual alphabet, at the speed you choose, on either hand. Click a key, or just press it on your keyboard.

Tip: press any letter or number key to sign it instantly.
Spell anything
Type a word and watch it spelled letter by letter, with each key lighting up as the hand reaches it. Names, places, and anything with no sign of its own are exactly what fingerspelling is for.
Practice reading it
Reading fingerspelling is the harder half, and it only comes from repetition. The avatar spells something; you type what you read. Your streak is kept on this device.
Fingerspelling is one part of American Sign Language: it spells names, loanwords, and anything with no sign of its own. Words that have signs are signed, and you can watch those, get signed AI chat replies, and sign back with your webcam at /sign-language. The full reference is in the documentation, and the engine behind both pages is published as @three-ws/sign-language.
