The genesis of NovaLecture AI came from a simple observation: students are drowning in content. We built this tool to bridge the gap between passive viewing and active recall.

We modeled information density as: $$ I = \sum_{i=1}^{n} \frac{T_i}{V} $$

By leveraging Nova 2 Lite's low-latency reasoning, we can process a 60-minute lecture into an interactive kit in under 20 seconds.
