## What it is
Quiver is a web-based graphical editor for creating commutative and pasting diagrams used in category theory and mathematics. It renders high-quality diagrams and exports them to LaTeX via tikz-cd or Typst via fletcher.

## Use cases
- draw commutative diagrams for a category theory paper
- export a diagram to tikz-cd LaTeX code
- create pullback and pushout diagrams visually
- make pasting diagrams for higher category theory
- convert hand-drawn math diagrams into Typst fletcher code
- quickly sketch adjunction diagrams without writing LaTeX

## When to choose
- you need commutative or pasting diagrams for LaTeX or Typst documents
- writing tikz-cd code by hand is too slow or error-prone
- you want a fast, keyboard-friendly visual diagram editor in the browser

## When to avoid
- you need general-purpose diagramming like flowcharts or UML
- you require offline desktop editing without a browser
- you need diagrams outside the commutative-diagram paradigm

## Facets
- artifact type: application
- maturity: active
- function: editor, graphics, documentation
- domain: mathematics, web-development, education, developer-tools
- platform: browser, cross-platform
