I Tested Google NotebookLM vs ChatGPT on a 100-Page Endocrinology PDF: Which is Better for Medical Physiology?
Last week, I found myself staring at a 100-page Endocrinology PDF at 2:00 AM. If you are a medical student, you probably know the feeling already. Hormone synthesis pathways, endocrine syndromes, receptor mechanisms, and endless feedback loops compressed into one chaotic lecture deck just days before an integration exam. At that moment, I decided to try something different. Instead of spending hours manually organizing slides, I uploaded the same endocrinology PDF into two AI tools that medical students keep talking about right now: Google NotebookLM and ChatGPT (GPT-4o) . My goal was simple: Which AI actually helps with medical physiology? Which one improves understanding instead of just summarizing? And which one is more useful for difficult mechanistic topics like endocrine feedback loops? After several hours of testing, I realized the two tools solve completely different problems. The Real Problem With Medica...
