Tactile Diagram Workbench

Tactile Diagram Workbench is an open-source braille compiler for blind STEM students. A teacher can upload a textbook diagram, photograph a hand-drawn sketch, or type a concept like “draw acetone,” and the workbench turns it into an export-ready tactile sheet: raised-line SVG/PDF for swell paper or tactile-graphics embossers, plus .brf braille labels for standard text embossers. Chemistry diagrams use a verified pipeline with canonical SMILES and deterministic structure checks; other STEM diagrams route into a clearly labeled teacher-review draft lane so teachers can still produce usable tactile materials without pretending they are fully verified. The goal is to move tactile STEM diagrams from a weeks-long procurement workflow into the same class period.
