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

1.6.33 Sept 2026
Bug Fixes and Improvements:
- Fixed the problem that the add page button below the last page could cause undefined behavior when tapped by a finger, and not respond to stylus input at all.
- Fixed the problem that the missing pdf banner could not respond to stylus input, and physically shift during a viewport scroll.
- Fixed the problem that text annotations could be moved with the ObjectSelect tool.
- Fixed the problem that the PDF exporting tab would still show up right after an edgeless document was exported before saving, causing an invalid pdf range error.
