SpeedyNote is an open-source note-taking application, written in native C++ and Qt, specifically designed for stylus users who require high-quality input and annotation performance on low-cost hardware. It provides a 360 Hz stylus polling rate on processors like the Intel Celeron N4000, allows annotation of PDF files with pressure-sensitive ink tools rendered as vector strokes, and offers organization modes such as paginated notebooks or borderless canvases with lazy loading, all with an interface optimized for tablets and touch.
