This repository is a fork of original author varkor's diagram editor quiver. We're in the process of "wrapping"/modifying it in order to make it more responsive to various screen sizes. On touch screens, we ensure everything works properly. Varkor did an excellent job already - placing objects / arrows works already almost 100% perfectly on your phone.
quiver is a modern, graphical editor for commutative and pasting diagrams, capable of rendering high-quality diagrams for screen viewing, and exporting to LaTeX via tikz-cd. -varkor
Mathematical areas of use include Category Theory, Homological Algebra, Topos Theory, and essentially any heavily arrow-based subject.
Creating and modifying diagrams with quiver is orders of magnitude faster than writing the equivalent LaTeX by hand and, with a little experience, competes with pen-and-paper. -varkor
