Key Features: - Context-Aware Translation: Understands the connection between paragraphs to prevent translation errors caused by fragmented text. - Smart Layout: Delivers a clean, bilingual reading experience optimized for long articles, research papers, and eBooks. - Native Integration: Designed exclusively for Safari for a fast, seamless, and lightweight browsing experience.
