MarginNote4 now released!
Refined over ten years, inspired by the academic journeys of many extraordinary learners, this all-in-one app is designed to empower everyone to embrace active learning.
How MarginNote defines learning?
Mastery in learning is the fruit of a long, iterative cognitive process.
Accumulate our understanding, spark new ideas, and gradually reshape our knowledge without losing past achievements. Through comparison and contrast, we distill essence from existence.
How MarginNote empowers learning?
MarginNote is designed for metacognitive learning. From highlights, annotations to pen strokes, every interaction is uniquely stamped with moments and contexts. Formerly created note cards are visualized, reorganized, and referenced for future studies.
