Figviz

Figviz generates labeled science diagrams from plain-text prompts. Describe a biology, chemistry, or physics concept — "plant cell with labeled organelles", "the water cycle", "a DNA replication fork" — and Figviz produces a clean, accurately labeled diagram ready for lessons, homework, slides, or publications. It is built for teachers, students, and researchers who need publication-style figures without learning a full illustration tool. Diagrams can be exported for documents and slides, and developers can generate figures programmatically through an API and an MCP server that works inside AI assistants. Figviz is freemium: free credits to start, paid plans for higher volume.
