Felix Zwettler

Felix Zwettler is an independent software publisher dedicated to advancing open-source note-taking and sketching tools through the development of Rnote, a vector-based handwriting application designed for students, educators, designers, and anyone who prefers stylus or finger input over keyboard typing. Built with Rust and GTK4, Rnote provides a cross-platform workspace that behaves like an infinite sheet of digital paper, supporting pressure-sensitive strokes, shape recognition, layered editing, and PDF annotation so lecture slides, journal templates, or design briefs can be imported, marked up, and exported as SVG, PDF, or PNG without losing resolution. Typical workflows include lecture note-taking with synchronized audio, quick UI wireframing, math problem solving that benefits from infinite scroll, and field sketching where offline operation and low latency matter. The interface is intentionally minimal, allowing users to map pen buttons to tools such as eraser, selector, or infinite canvas mover, while a configurable toolbar keeps colors, stroke widths, and vector shapes one tap away. Because the file format is open and compressed, notes remain future-proof and lightweight for Git-based version control or cloud sync. Felix Zwettler’s Rnote is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources like winget, always installing the latest release and supporting batch deployment alongside other applications.
