AI is built in to help you dive deeper into grammar, vocabulary, and context. CAN I LEARN MORE EFFECTIVELY? Yes! Subix lets you display dual subtitles so you can follow two languages at the same time. This makes it easier to connect meaning and structure while you watch. WHAT ABOUT LONG-TERM LEARNING? We know progress comes with practice. That’s why we’re working on a flashcard system inspired by Anki, so you can review and memorize the phrases you’ve encountered in your movies. WHY SUBIX?
