PaperBanana: AI Academic Illustration Generator
Google Cloud AI Research and Peking University · Image · Productivity
PaperBanana is an AI academic illustration generator that turns raw research text into publication-ready diagrams, method figures, and statistical plots. Built by Google Cloud AI Research and Peking University, it runs five specialized agents in sequence to plan, style, and refine each figure until it holds up in a paper. You sign in with Google, describe what you need, and download the result. It targets researchers, graduate students, and anyone tired of redrawing figures in TikZ or Illustrator.
About PaperBanana: AI Academic Illustration Generator
What Is PaperBanana
PaperBanana is an agentic framework for automated academic illustration. You feed it a method description, a raw dataset, or a rough sketch, and it returns a figure that follows the conventions of top-tier venues.
The problem it solves is real. Text tasks have gotten fast for AI scientists, but the figure at the end of the paper still eats hours that could go into the experiments themselves. TikZ and Python-PPTX give you structure but no visual flair. Image generators give you flair but distort your numbers. As a dedicated AI diagram generator, PaperBanana splits the difference by planning the layout first, then rendering, then checking its own work.
Its main limit is scope. PaperBanana is built for scientific illustrations, not general graphic design. Ask it for a logo or a social banner and you're using the wrong tool. It also leans on reference examples from published papers, so unusual or brand-new diagram types may come back less polished than standard method figures.
Getting Started
- Go to the PaperBanana site and sign in with your Google account.
- Paste your research content, method text, or dataset into the prompt box.
- Pick a model, a style guide, an aspect ratio, and a target resolution.
- Hit Generate Images and let the agent pipeline plan, style, and render the figure.
- Review the output, then download it as a high-resolution image or grab the underlying code for further tweaks.

Key features
Five-Agent Pipeline
PaperBanana splits the drawing job across five roles: a Retriever, a Planner, a Stylist, a Visualizer, and a Critic. The Retriever pulls relevant reference examples. The Planner turns your text into a visual blueprint. The Stylist aligns it with academic aesthetics. The Visualizer renders it. The Critic checks the result against your input. That division of labor is what separates it from a single-prompt image generator.
Reference-Driven Generation
The framework retrieves similar figures from published work before it draws anything. Those examples act as strong priors for layout, labels, and annotation style, so a new diagram inherits the visual language of figures that already cleared review at a major venue. Less fiddling with style instructions.
Iterative Self-Critique
The Critic agent inspects each generated image against the source content and sends feedback back through the pipeline. This loop repeats until the figure is judged publication-ready. It's the part that catches a mislabeled box or a missing arrow before you do.
Method Diagrams and Statistical Plots
PaperBanana handles both illustration types researchers actually need. Method diagrams cover architectures, pipelines, and workflows. Statistical plots cover bar charts, line charts, and similar figures, with a code-generation mode that produces executable Python Matplotlib code for accuracy. You can download the figure or the code behind it.
High-Resolution Download
Output arrives at high resolution and is sized for direct insertion into LaTeX or Word. No upscaling. No redrawing in a vector editor before you drop it into a submission.
Free Browser Access
You sign in with Google and generate your first illustration without paying. There's no install, no plugin, and no local GPU requirement.
Pros and cons
Pros
- Cuts down the time spent on figure preparation, especially for standard method diagrams.
- The five-agent design produces better-structured figures than a single text-to-image prompt.
- Code generation for plots keeps chart values tied to your real data instead of a model's guess.
- Free to start through Google sign-in, with no software to install.
- Output resolution fits straight into LaTeX and Word workflows.
Cons
- Pricing for paid tiers isn't published, so you can't budget for heavy use yet.
- Reference-driven generation means unusual diagram types may come back less refined than standard ones.
- It's built for scientific illustration, not general design. The wrong tool for logos or marketing art.
- You still need to verify every label, arrow, and number before submitting, since no automated critic catches every error that a careful reviewer would.
Frequently asked questions
PaperBanana generates academic illustrations from text. You describe a method, a concept, or a dataset, and it produces a diagram or plot ready for a paper, a slide deck, or technical documentation. It's aimed at the figure-drawing step of research, not at general graphic design.

X Ray Interpreter
X-ray Interpreter · ImageX Ray Interpreter is a web-based AI radiology tool that turns X-rays, CT scans, MRI, ultrasound, and PET images into plain-language reports. You upload a scan, get a preliminary X-ray interpretation in moments, then ask follow-up questions if something needs explaining. It works as a second opinion and a learning aid, not as a medical diagnosis.
Aieasypic
AIEasyPic · ImageAIEasyPic is an AI image generator that turns plain text prompts into finished artwork in seconds. You can also train custom models on your own photos, swap faces in existing images, and create short video clips from text, all from a browser. It suits casual creators who want quick visuals and hobbyists who want to build a personal model without touching any code.
Chargen
Chargen · ImageChargen is an AI character generator and worldbuilding toolkit built for Dungeons & Dragons and other tabletop RPGs. It turns a one-line idea into a painted character portrait, spins up NPCs, monsters, maps and encounters from the same session, and keeps every creature's details close at hand. The tabletop RPG art side runs on a credit system called Gold, while the text generators stay free for everyone.
