Unicaption
Real-time AI captioning and translation copilot for human interpreters. Live speech-to-text at 98.5% accuracy with under 200 ms latency, automatic language detection across 100+ languages, and instant translation — in the browser, desktop app, or Chrome extension. HIPAA, SOC 2, and GDPR compliant. A copilot, not a replacement.
What it is
Unicaption is a live captioning and translation tool built for professional interpreters — medical, legal, government, and business. It listens to the call, shows every word as text in real time, and translates on the fly, so the interpreter can glance instead of straining to catch every word. It works in the browser alongside Zoom, Teams, or any agency platform; nothing to install for the web app. Over 2,000 interpreters use it.
Key numbers:
- 98.5% transcription accuracy
- Under 200 ms latency — text appears almost as the speaker talks
- 100+ languages with automatic language detection (no manual switching mid-session)
- Built-in terminology for healthcare, legal, and government interpretation
Privacy and compliance: sessions are end-to-end encrypted, audio is never stored, transcripts are deleted when the session ends. HIPAA compliant (safe for medical calls and PHI), SOC 2, and GDPR.
Positioning: Unicaption is a copilot, not a replacement. Interpretation requires judgment, empathy, and cultural understanding — Unicaption handles the cognitive load so the interpreter can focus on the human work.
