Figviz

Figviz turns a sentence, a topic, or a PDF into an accurate, labeled diagram for biology, chemistry, physics, and K-12 math — cell diagrams, reaction mechanisms, free-body diagrams, function graphs, and more. Built for STEM teachers and students: generate a clean, labeled figure in seconds and export a print-ready PNG for worksheets, slides, and papers. It also includes 150+ free diagram tools and interactive concept pages (drag-to-explore math, physics, and chemistry). No subscription — start free with 3 credits, then pay-as-you-go. Figviz is built for education first: the diagrams are scientifically accurate and labeled, so they are ready to drop into a worksheet, a lab report, or a slide deck without extra editing. Developers can also generate labeled science and math diagrams from text via the Figviz API, with a free key included.
