Mission
Built by the people who use it.
SignBridge exists because real-time sign translation should be free, accurate, and shaped by the deaf community. We’re a small team building tools the community owns — not a black-box product that decides for you.
Privacy by design: no video is ever recorded. Only abstract numerical hand position data leaves your device, and only when you choose to contribute.
Help build SignBridge.
Every recorded sign from a new contributor makes the model better at recognizing real-world signing. It takes about a minute to sign one word.
