Optional sharing for this recording session

Both choices are off by default and are separate from the private-training agreement. Changes apply to new submissions in this session.

  • Frame yourself from the waist up with both hands free.
  • Keep a plain background and even lighting on your hands.
  • Sign at a natural pace — start and end with hands at rest.

Signs that need clips most

Each sign trains best with about 20 clips from different people. Pick one of these to have the biggest impact.

Your video stays yours

Recording and landmark extraction run entirely in your browser. Nothing is sent anywhere until you press submit.

Reviewed before it counts

A human reviewer checks labels and recording quality before an approved sample can be used for training. Public display is a separate choice.

Private training by default

Your video and landmarks stay private for review, training and validation. Public display and third-party transfer require separate optional permission.
