Xournal++ is a free and open-source handwriting notetaker, PDF annotator, and sketch application developed by a community of contributors. It combines the ease of use of paper notebooks with the power of digital tools, allowing users to take notes with a stylus, sketch diagrams, and annotate existing PDF documents.

It's primarily built for students, educators, and professionals who frequently work with digital documents and prefer a natural handwriting experience on touch-enabled devices.

Why It’s Useful
Xournal++ offers a superior open-source alternative to proprietary note-taking apps like OneNote or GoodNotes, especially for users who value a fluid handwriting experience and PDF annotation. For the university student, it's invaluable for annotating lecture slides, solving math problems, and diagramming concepts directly on their tablet, enhancing their active learning process without subscription costs. For the engineer or designer, it's perfect for sketching out quick ideas, marking up blueprints, or collaborating on designs in real-time during virtual meetings. Xournal++ is completely free and open-source, maintained by a dedicated community. A hidden gem is its advanced layer management, which allows users to organize complex notes or drawings with different elements on separate layers, enabling easy toggling and reordering. Its niche appeal, mainly among Linux users initially, and less aggressive marketing contribute to its lower popularity, but it has a growing cross-platform community, regular updates, and extensive customization options.
