PaperBanana
AI illustration · Retrieve · Plan · Style · Visualize · Critique

Turn research briefs into publication-ready figures.

PaperBanana is an end-to-end AI pipeline for scientific diagrams, flowcharts, architectures, concept maps, schematics, and data plots — with a built-in critic that keeps iterating until the figure is actually good.

Built for scientists, engineers, and technical writers.

🔍

Six figure families

Diagrams, flowcharts, architectures, concept maps, schematics, scientific visualizations. One engine, many shapes.

🎨

Style presets

Journal-clean, poster-bold, thesis-formal, training-friendly, SOP-workflow. Or build your own palette + typography.

🧪

Code-based plots

When numeric fidelity matters, PaperBanana emits exact Chart.js specs — not pixelated renders.

🧠

Built-in critic

Every figure is scored on faithfulness, simplicity, readability, and aesthetics. Low scores trigger auto-refinement.

🖼️

High-resolution output

Export to HTML, Mermaid source, or PNG. Optimized for paper, poster, and presentation mediums.

🔁

Refinement loop

Tell the Critic what's wrong. It rewrites the Visualizer prompt and tries again — until the figure is acceptable.

The 5-stage illustration pipeline.

1

Retriever

Extracts entities, relationships, and keywords from your brief, image, or dataset.

2

Planner

Designs the layout — top-down, radial, grid — decides sections, items, and annotations.

3

Stylist

Applies your chosen palette and typography to the plan. Journal-ready by default.

4

Visualizer

Emits concrete artifacts — Mermaid for diagrams, Chart.js for plots, SVG for schematics.

5

Critic

Scores the figure on 4 axes. If it falls short, the pipeline refines and tries again.

Style built for your medium.

Journal Clean

Minimal black & white for peer-reviewed journals.

Poster Bold

High-contrast palette for conference posters.

Thesis Formal

Neutral greys, serif typography — dissertation-ready.

Training Friendly

Warm, approachable palette for e-learning decks.

SOP Workflow

Procedural colors for SOPs and workflow diagrams.

Concept Pastel

Soft pastels for concept maps and ideation.
