What it does
Diagraw combines freehand shapes, attached arrows, comments, cursors, and version history on an infinite canvas. Its official site describes Mermaid and docker-compose import or export, cloud architecture icons, and PNG, SVG, or PDF exports. The vendor’s indexed Spanish pages describe a free plan for the core canvas and Pro at €6 per month or €60 per year.
Diagraw is oriented toward turning a shared sketch into a usable diagram: shapes keep their attached arrows, multiple people can work on the same canvas, and saved boards can be exported or versioned. The same canvas is marketed for teaching and system-design work. The official English site and Spanish pricing text were available through search excerpts, but direct page retrieval failed during this check, so confirm current availability and localized pricing before publication.
