Built with the Deaf community. Designed for real impact.


How it works
1. Kara Translator
Our AI converts English text into our Kara Notation System (KNS), a structured representation that captures grammar, morphology, phonology, emotions, and sentiment - elements essential for accurate sign language translation.
2. Sign Language Blending Engine
Using our extensive sign language database, the system generates lifelike motions, ensuring smooth, natural signing that aligns with linguistic and cultural nuances.
3. Real-time Rendering
The final translation is rendered into a high-quality sign language video, ready for immediate use.
