The Communication Gap is Real

466 million people are deaf or hard-of-hearing. Current tools are slow, robotic, or require human interpreters.

🐌

Slow & Expensive

Interpreters cost $50-150/hr. Not scalable for daily chats.

🤖

Robotic Avatars

Existing avatars are uncanny, lack emotion and smooth signing.

🔒

No Privacy

Cloud-only solutions can't be used in hospitals or schools.
