draw-a-ui is an open-source app that uses tldraw and a vision model to generate HTML from a drawn wireframe. Its repository links to Terragon Labs as its spiritual successor.
How SketchMason approaches the job
Draw labelled regions on a canvas, or drop in a photo of a sketch on paper, add a mood board and generate a UI design beside the sketch. Refine the result and develop related screens with the same visual direction. Export the design as HTML or a written brief.
Which workflow fits your next step?
Choose draw-a-ui when you want to explore or adapt an open-source drawing-to-HTML implementation. Choose SketchMason when you want to work in a hosted design canvas, use a mood board and develop related screens.
