## What it is
SpeedyNote is a free, open-source, cross-platform note-taking application built in C++ with Qt, designed for stylus users who need fast PDF annotation and handwriting on low-end hardware. It offers pressure-sensitive inking, multi-layer editing, paged notebooks, and an edgeless infinite canvas across Windows, Linux, macOS, Android, and iPadOS.

## Use cases
- annotate pdfs with a stylus on a cheap laptop
- take handwritten lecture notes on a budget tablet
- replace OneNote for pdf annotation
- use an infinite whiteboard canvas for brainstorming
- run a fast note app on low-end hardware like a Celeron chromebook
- share handwritten notes across devices
- palm rejection and touch gesture note-taking on android tablets

## When to choose
- you need fast PDF annotation on low-end or ARM hardware
- you want a free alternative to GoodNotes or Notability without an iPad
- you need cross-platform handwritten notes including Android and iPadOS
- you want vector strokes, layers, and pressure sensitivity in a native app

## When to avoid
- you need rich text typing, cloud sync, or collaboration features
- you want a plugin ecosystem or deep integration with other productivity tools
- you need OCR or handwriting-to-text conversion
