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.
