The moment it clicks
“I was reviewing cardiac pharmacology and normally would have spent hours going back through lecture slides, textbook chapters, and old notes to connect everything. Twinbook compressed that into a personalized high-yield note — broad enough to see the whole pathway, but detailed enough to drill into mechanisms, exceptions, and weak spots. That's when I realized this wasn't just another AI summary. It was a better way to move through complex medical content.”
