READ AND TRANSLATE PDFs • View the original text and its translation side by side. • Scroll both versions together to keep the same passage aligned. • Keep the source visible while you highlight, annotate and handwrite. FOLLOW LECTURES IN TWO LANGUAGES • Record a lecture and see bilingual captions on supported devices. • Review a timestamped bilingual transcript after class. • Jump back to the relevant moment instead of searching the entire recording.
