How it works

  1. Show your hand

    Any webcam will do. Face a light and keep your palm toward the camera.

  2. Hold until the ring fills

    A steady handshape locks the letter. Fast is good; clean is better.

  3. Beat your best

    Letters per minute is the only score. Your last run is the one to beat.

Other ways to practiceNo clock, your own words, or one letter at a time.

  • Zen

    Untimed. Your letters per minute come from the time you actually spend; the clock pauses when your hand leaves the frame. Finish (or Esc) ends it.

  • Your words

    Sign your name, or any list. Letters A to Z, 2 to 12 a word. They stay on this page, never saved or sent.

  • One letter

    Open any letter in the alphabet below for its handshape, its look-alikes and “Practice this letter”.

Words · betaWhole signs, one at a time. Tap a sign for its replay.

16 everyday signs, recognized on your device. Trained on Deaf signers’ recordings. It may not know regional or two-handed variants yet — “Couldn’t confirm” doesn’t mean you’re wrong.

10 signs a round, untimed. Keep your head and shoulders in view.

The alphabetAn index of handshapes. Tap one for its cue and look-alikes.

In a test that held out each of 10 signers from one photo dataset, 94.9% of still images were labeled correctly (24 static letters). J and Z use motion tracking. Live webcam accuracy is lower and not yet measured; lighting, angle and handshape all matter.
