Paper Banana

Paper Banana is an AI academic illustration generator built for researchers, PhD students, professors and educators. Describe the diagram you need, from a system architecture or experimental setup to a workflow or concept map, choose a style, and receive a high-resolution figure ready for a paper, poster, thesis or lecture slide. A five-agent pipeline (Retriever, Planner, Stylist, Visualizer, Critic) keeps each figure faithful to your text and easy to read. You can also start from an existing image, refine regions in the editor, and use 40+ specialized makers for PRISMA and CONSORT flow diagrams, forest, volcano and Kaplan-Meier plots, phylogenetic trees and graphical abstracts. Free tools include a journal figure checker and an image format converter.
