Designing Notes Like CPU Memory: Why Two-Tier Architecture Beats Unified Storage

Traditional note apps fail to address the conflicting demands of capture and storage—speed and accessibility versus searchability and durability. This framework applies CPU memory hierarchy principles to personal knowledge systems, demonstrating how splitting capture (fast mobile L1) from curation (organized desktop L2) solves problems that no single technology can address. The model offers a paradigm shift for how product designers and users alike should approach productivity tool architecture.
