Build a local-first Android notebook optimized for stylus input, PDF^? annotation, folders, and instant search across typed text, handwriting, and imported documents. Store notebooks in an open, exportable format and provide user-controlled synchronization through common file-storage providers. Start with the narrow workflow of importing a course PDF^?, writing without perceptible lag, and finding the resulting page later by subject or recognized text.

Android tablets and high-refresh-rate styluses are increasingly capable study devices, while the reviews show that note software still fails to deliver consistent native performance and data portability. Users explicitly report switching products or withholding payment because of these shortcomings.
