What is paper banana?

PaperBanana (paperbana.com) is a web-based academic illustration generator that turns paper text, figure captions, references and rough sketches into methodology diagrams, statistical plots and other research figures. The site describes itself as an independent, third-party service that provides online access to the open-source PaperBanana framework, and states that it is not affiliated with Google, Peking University or the original project authors. The publisher names PhD students, lab researchers, startup research teams and paper authors as its audience, for figures used in papers, posters and slides.

Users paste a method section or notes, add a short figure caption, and set a maximum number of iterations and an aspect ratio such as 1:1, 4:3, 16:9 or 21:9. The site says the workflow maps stages, blocks and flow before rendering, and that a self-critique loop can revise wording, spacing and composition. Separate tools cover image-to-image generation from sketches and reference images, a text-instruction editor for revising existing figures, an image upscaler, and an Image to Editable SVG converter in beta.

A prompt library lists 66 prompts across 11 categories, with examples such as RAG pipelines, transformer architectures, cell-signaling pathways and benchmark charts. Paid generation uses models listed as GPT Image 2, Nano Banana and Nano Banana Pro. Pricing is credit-based.

A Free Draft mode produces previews with limited detail and a watermark, and sign-in is required before generation. Pro is $24.99 per month for 500 credits and Premium is $59.99 per month for 2,000 credits; yearly billing, one-time credit packs and custom Institution pricing are also listed. The site shows a credit estimate before a job runs and says unused credits may be returned if a task finishes early or fails because of a system issue.

Pricing: Free Draft previews (watermarked); Pro $24.99/month (500 credits); Premium $59.99/month (2,000 credits); yearly plans, one-time credit packs, custom Institution pricing

FAQs

Common questions about paper banana

Is PaperBanana free?
Partly. A Free Draft mode produces previews with limited detail and a watermark, and sign-in is required before generation. Cleaner output uses paid models and credits. Pro is $24.99 per month for 500 credits and Premium is $59.99 per month for 2,000 credits. Yearly billing, one-time credit packs and custom Institution pricing are also listed. The pricing page says starter credits may be offered to new accounts, and the amount can change.
Who runs paperbana.com?
The site calls itself an independent third-party platform that provides online access to the open-source PaperBanana framework. It says it is not affiliated with, endorsed by or officially connected to Google, Peking University or the original project authors. Its terms of service say the service is operated by PaperBanana.
What kinds of figures can it create?
The publisher lists model architecture diagrams, multi-stage pipelines, flowcharts, system overviews and figure panels, along with statistical and benchmark plots, poster panels, graphical abstracts and mechanism pathway figures. Its prompt library also covers engineering systems, life-science mechanisms and academic writing workflows.
Can it clean up a hand-drawn sketch or an existing figure?
Yes. You can upload a rough sketch, old diagram, low-resolution export or figure screenshot as a reference and describe the revision you want. The site says it can keep the rough layout while cleaning up the look, spacing, labels and overall illustration quality. A separate upscaler improves the resolution of exported figures.
How do credits work?
Each generation or refinement job uses credits, and the expected cost is shown before you run it when available. Listed costs include 29 credits for Methodology Diagram Drafting, 15 for Sketch Cleanup and Redraw, and 10 for Image to Editable SVG. Unused credits may be returned if a task finishes early or fails because of a system issue. A first-time customer can request a pro-rated refund within 14 days if unused paid credits remain.
What platforms does it run on?
The terms describe PaperBanana as a set of web-based workflows, and sign-in is required before generation. The publisher does not mention a desktop or mobile app.
