From methodology flowcharts to cell signaling pathways — describe your diagram and let PaperBanana's multi-agent AI pipeline generate publication-ready scientific illustrations with fully editable SVG output for NeurIPS, Nature, and beyond.
PaperBanana is an AI-powered academic diagram generator that transforms plain-text descriptions into publication-quality scientific illustrations. Under the hood, a multi-agent pipeline — Planner, Stylist, Critic, and Visualizer — collaborates to produce precise, visually consistent diagrams. It supports 12+ diagram types spanning Computer Science, Biology, Chemistry, Medicine, Business, and Engineering, with 8 visual styles and 9 AI models to choose from.

Six reasons PaperBanana is the go-to AI music video generator for independent artists, content creators, and music producers.
Four specialized AI agents work in sequence: the Planner analyzes your methodology, the Stylist refines aesthetics, the Critic reviews quality, and the Visualizer renders your diagram.
From flowcharts and neural network architectures to cell signaling pathways, chemical synthesis routes, and business model canvases. Each type comes with curated subtemplates.
Choose Academic for clean journal-ready diagrams, Blueprint for technical drawings, Hand-drawn for organic sketches, or 3D Isometric for perspective views.
Upload a rough sketch or existing diagram, describe what to change. Upgrade color schemes, add labels, modernize layouts, or convert hand-drawn sketches into polished illustrations.
Nano Banana 2 for fast previews, Nano Banana Pro for precise text rendering, SeedDream for photorealistic output, GPT-4o for complex instructions, and Midjourney for artistic styles.
Generate up to 10 diagram variations in a single click. Use Edit Region to paint over specific areas and regenerate just that section without redoing the entire figure.
Cell signaling pathways, protein structures, gene regulatory networks, drug mechanism diagrams — biomedical papers demand far more visual complexity than CS figures.
From photosynthesis light reactions and Calvin cycle to root-shoot signaling and phytohormone pathways — clear botanical illustrations for Plant Cell and New Phytologist.
Bacterial quorum sensing networks, viral replication cycles, microbiome community interactions — precise diagrams for Nature Microbiology and mBio.
Everything you need to create publication-quality scientific diagrams — from text description to journal-ready illustration.
Our proprietary four-agent pipeline delivers results no single AI model can match. The Planner analyzes your methodology text and creates a detailed visual specification. The Stylist applies NeurIPS-grade aesthetics. The Critic iteratively reviews for accuracy. The Visualizer renders the final image using state-of-the-art models.
From neural network architectures to cell signaling pathways, chemical synthesis routes to business model canvases — PaperBanana covers every scientific discipline. Each type comes with curated sub-templates pre-filled with domain-specific structure, so you get accurate results even with minimal prompting.
Academic for clean journal figures. Blueprint for technical drawings. Hand-drawn for organic sketches. Isometric for 3D perspectives. Each style is carefully tuned with specific color palettes, typography, and layout conventions that match real-world publication standards.
Already have a rough sketch or an outdated diagram? Upload it and describe what to change. PaperBanana enhances existing diagrams — upgrade color schemes, add labels, modernize layouts, or convert hand-drawn sketches into polished digital illustrations. Reference multiple images using @img1, @img2 tags.
Generate up to 10 diagram variations from a single prompt in one click. All requests run in parallel, so you get results fast. Compare variations side by side, pick the best one, and iterate on specific elements without regenerating everything.
Found a near-perfect diagram but one label is wrong? Paint over that specific area with the blue brush tool and describe what to change. PaperBanana regenerates only the painted region while keeping everything else intact — no need to start from scratch.
Every new user gets 20 free credits with no credit card required. That’s enough to generate several publication-quality diagrams and experience the full multi-agent pipeline before deciding to upgrade.
Every diagram follows strict academic conventions — clean white backgrounds, proper component labeling, consistent sans-serif typography, and soft pastel color palettes used in Nature, NeurIPS, and ICML publications.
What used to take 3-4 hours in Adobe Illustrator or PowerPoint now takes under 60 seconds. Describe your diagram in plain text, select a style, and get a polished result instantly. Iterate as many times as you need.
Computer Science, Biology, Chemistry, Medicine, Business, Engineering — PaperBanana supports 12+ scientific fields with specialized diagram templates and domain-specific visual conventions built into every generation.
“PaperBanana saved me hours of diagram work for my thesis. I described a neural network architecture in plain text and got a publication-ready figure in 30 seconds. My advisor was impressed by the quality — it looks like I hired a professional illustrator.”
PhD Candidate, MIT
“The biology diagram templates blew my mind. I described a cell signaling pathway and it created an accurate, beautifully labeled illustration. The level of detail is remarkable for an AI tool.”
Biomedical Engineer
“The Blueprint and Isometric styles are incredible for system architecture diagrams. I created figures for an entire textbook chapter and each one has a unique, professional look. My students love the visual clarity.”
