BioSketch.art is a browser-based figure builder for creating publication-ready scientific and medical illustrations. Users can assemble figures with editable vector icons, arrows, connectors, labels, and shapes on a fast canvas workspace, then export high-resolution graphics for papers, slides, posters, and patient education. The platform supports icon search and organized libraries (including personal uploads), grouping and alignment tools, annotation features, Bezier/freehand drawing, and project-based saving. BioSketch.art is built for open science: core tools and a large icon library are free to use, with optional Pro features for AI-assisted generation (e.g., icon/figure generation) and higher-usage workflows.
