Paper Banana

Paper Banana is an AI-powered tool for researchers, students, and educators who need publication-quality scientific visuals. Users describe the illustration they need in plain language and the tool generates a figure in seconds, offering several academic styles such as diagram, flowchart, architecture, concept map, and schematic. The page states that outputs are high-resolution and suitable for journal papers, conference posters, and thesis documents. It also lists an image editor for refining results, a Poster Maker that creates academic posters from PDF papers, a Diagram Maker for editable SVG diagrams from templates, and a Studio for editing selected areas of existing figures. The site reports benchmark results on PaperBananaBench (292 test cases from NeurIPS papers) across faithfulness, simplicity, readability, and aesthetics, and describes a five-agent pipeline (Retriever, Planner, Stylist, Visualizer, Critic). Paid plans are listed with monthly and yearly options and per-image cost estimates.
