Key Differentiator: Transync AI’s Dual-Screen Display

Why this matters for “How to translate English to Spanish”:

Traditional real-time translation (JotMe, Kudo):

• ❌ Shows one language at a time
• ❌ Have to switch views to see Spanish/English

• ❌ Miss context from original language

Transync AI’s dual-screen display:

• ✅ See English AND Spanish simultaneously
• ✅ Don’t need to switch views

• ✅ Easy to verify accuracy
• ✅ Better for note-taking
• ✅ Comprehension efficiency 40%+ higher

LEFT SCREEN (Original)          RIGHT SCREEN (Translation)
━━━━━━━━━━━━━━━━━━━━━━━━      ━━━━━━━━━━━━━━━━━━━━━━━━
Sales Rep: "Our CRM        →    Sales Rep: "Nuestro CRM
helps manage 50% more           ayuda a gestionar 50%
customers"                       más clientes"
Prospect: "¿Cuál es         →   Prospect: "What is
el precio?"                     the price?"
[BOTH visible simultaneously]
