About

SpeedyNote is a fast, open-source note-taking application designed for stylus users who need iPad-quality annotation on budget hardware. Built with native C++ and Qt, it delivers 360Hz stylus input on hardware as modest as an Intel Celeron N4000 at 1.1GHz — with no Electron bloat.

Annotate PDFs with pressure-sensitive inking tools including pen, marker, and highlighter, all rendered as vector strokes that zoom infinitely without pixelation. Organize your work with multi-layer editing, paged notebooks, or infinite edgeless canvases with lazy-loading tiles.

Key features include:

  • Instant PDF loading with clickable internal links and outline navigation
  • Multi-layer editing with add, delete, reorder, and merge operations
  • Touch gestures: two-finger pan, pinch-to-zoom, and palm rejection
  • Cross-platform note sharing via .snbx notebook packages
  • Powerful command-line interface for batch PDF export and notebook management
  • Multi-tab editing to work on multiple documents simultaneously
  • Auto-save so you never lose work
