About This Site
Free AI diagram generator for STEM science and math visuals. Figviz is a free AI diagram generator specifically built for STEM teachers, students, and researchers. Unlike generic AI image tools that often produce smeared text or scientifically incorrect layouts, Figviz is engineered to turn plain-English text descriptions or uploaded PDF references into accurate, labeled science and math diagrams. It adapts to different academic levels—ranging from K-12 classrooms to university-level research papers—and supports a variety of subjects like physics, biology, chemistry, earth science, and math. Users can easily export high-contrast, projector-ready diagrams as print-ready PNGs or editable SVG vector graphics for software like Adobe Illustrator, Figma, or Inkscape.
