Isara is a Deaf-community platform that includes an open Sign Language (SL) learning app, remote SL interpreter service, and crowdsourced video subtitle making tool. Isara offers fair business model by liberating SL learning so that anyone can easily learn SL at no charge. In return, students with hearing capability can help producing video subtitles. Our vision is to shift the paradigm of SL from a mere communication tool for the disabled into a true language as a part of the human culture.
