Break Down Language Barriers in Healthcare Opalite was built by founders who lived this problem. As children of immigrant parents who don't speak English, we watched our families struggle to communicate with doctors. As physicians, we saw firsthand how patients suffer when critical information gets lost in translation. So we built something better. Opalite is an AI medical interpreter that delivers real-time, speech-to-speech translation in over 150 languages. In validation studies with physician-researchers from Johns Hopkins and Stanford, Opalite showed 90% fewer errors than certified human interpreters. Instant access 24/7. No waiting for an interpreter. HIPAA compliant and SOC 2 Type II certified. Integrates directly with Epic and other major EHRs with automated clinical documentation. Works on any device you already have. From emergency rooms to community clinics, Opalite helps providers deliver better care to every patient, no matter what language they speak.
