Pros
  • Explore constructions built from points, vectors, lines, and polygons
  • Modify construction elements directly with the mouse
  • Create loci and extend functionality with Python-written macros
  • Drag base elements to update dependent parts of a construction.
  • Supports Euclidean, hyperbolic, and elliptic geometries.
  • Includes automatic proving, loci, CindyLab simulations, and CindyScript.
Cons
  • Desktop application for Linux and macOS, not an online classroom service
  • No proof practice or problem practice features
  • No classroom tools
  • Its scope centers on construction and exploration rather than proof practice.
  • Classroom and practice features are less extensive than some alternatives.
  • Documentation references older updates, which may complicate onboarding.
