PaperBanana is an open-source agentic framework designed to automate the creation of publication-ready academic illustrations for researchers. It generates high-quality methodology diagrams and statistical plots from textual descriptions or rough sketches, bridging the gap between research ideas and visual communication.

How does the agentic workflow operate?

PaperBanana employs a multi-agent system with four core stages: Retrieve gathers relevant context, Plan designs the layout, Render produces an initial image using advanced models, and Refine iteratively critiques and improves the output for enhanced faithfulness, conciseness, and aesthetics.

What kind of diagrams can I generate?

The framework is versatile, capable of producing complex methodology diagrams such as model architectures and flowcharts, as well as precise statistical plots. It handles both text-to-image generation and sketch polishing, covering most visual needs for academic papers.

Can I use it to polish my existing sketches?

Yes, PaperBanana's multimodal capabilities allow users to upload rough hand-drawn sketches. The system interprets the visual intent and refines it into a polished, professional diagram while preserving the original layout and ensuring style consistency.

Is this tool suitable for top-tier conferences?

PaperBanana is benchmarked against standards from leading AI conferences like NeurIPS. Its evaluation metrics focus on faithfulness, conciseness, readability, and aesthetics, demonstrating consistent performance that meets the rigorous requirements for publication in prestigious venues.

Is PaperBanana open source?

Yes, PaperBanana is an open-source project. The code, data, and models are publicly available on GitHub, and the research is detailed in an ArXiv paper. This openness encourages community collaboration and innovation in automated scientific illustration.

Do I need to be an expert in design?

No, PaperBanana is specifically designed for researchers without design expertise. Users only need to provide scientific context or sketches; the agentic framework handles layout planning, rendering, and aesthetic refinement to produce professional-quality figures.

How does the credit system work for generating illustrations?

PaperBanana uses a credit-based model where each illustration generation task consumes 29 credits. If the framework completes the task before exhausting all allocated iterations, unused credits are automatically refunded. Detailed pricing structures and credit packages are available on the official Pricing page.

What is PaperBananaBench and why is it important?

PaperBananaBench is a comprehensive benchmark dataset containing 292 curated test cases extracted from NeurIPS 2025 papers. It provides a standardized evaluation suite for automated illustration tools, enabling objective comparisons of faithfulness, conciseness, and aesthetics across different systems.

How does PaperBanana ensure the accuracy of generated diagrams?

Accuracy is ensured through a self-critique mechanism where specialized agents rigorously evaluate outputs against the source context. The iterative refinement process continuously improves faithfulness to the input data and adherence to academic standards, minimizing hallucinations or errors.

Can PaperBanana be applied to non-AI research fields?

While PaperBanana is optimized for AI research and benchmarked on AI conference papers, its core functionality for generating methodology diagrams and statistical plots is adaptable to other scientific disciplines. Effectiveness may vary depending on domain-specific visualization conventions.
