FigEditor is an AI scientific figure generator built to turn research ideas, sketches, references, and existing images into polished, editable visuals for papers, posters, and presentations. Start with a text prompt describing a mechanism, pathway, workflow, experiment, or architecture, upload a rough sketch, or provide a reference image to guide composition, palette, density, and visual hierarchy. FigEditor creates a structured draft with clear labels, arrows, and organized layout, then lets researchers revise text, shapes, colors, connectors, modules, and individual regions without rebuilding the entire figure. Existing PNG or JPG figures can also be vectorized into scalable assets for further editing. Its AI Scientific Illustration workflow uses a multi-step pipeline to generate a draft, detect visual elements, extract clean assets, assemble a structured SVG, and refine the final vector output.
