FAQ
Common answers about PaperBanana tools, credits, billing, refunds, and usage rights
Use this page for quick answers. If something is broken right now, start with Troubleshooting.
Start here
Which tool should I use?
Use Scientific Diagram Maker for structured mechanism diagrams, workflows, pathways, and graphical abstracts. Use AI Scientific Illustration for polished image-style illustrations. Use Scientific Poster Maker for conference and lab-meeting posters.
Can I use generated figures in papers or presentations?
Yes, but you are responsible for checking scientific accuracy, labels, rights, and journal or conference requirements before use.
What should I check before academic use?
Check the scientific claim, labels, arrows, scale, legends, author information, and whether the figure matches your source material. See What PaperBanana is not for for product boundaries.
Credits and billing
Why did my credits change?
Credit changes may come from generation usage, AI edits, subscription renewals, credit pack purchases, refunds, subscription credit expiration, or support adjustments. For the full lifecycle, see Credits and Billing.
Do subscription credits expire?
Yes. Subscription credits expire after 30 days. One-time credit packs currently do not expire.
Why are credits missing after a new subscription?
Credits are granted after payment confirmation. If payment succeeded but credits did not arrive after a few minutes, follow Troubleshooting and contact support with your account email and transaction details.
How long do refunds take?
Refunds usually take 5 to 10 business days, depending on the bank or payment provider.
Generation and editing
How do I write a better prompt?
Describe the figure type, panel structure, required labels, relationships, and visual style. Start from the Prompt Cookbook when you want a reusable template.
Can I edit text inside generated diagrams?
If the result is an editable SVG, you can edit text manually in Workspace Editor or use a small AI edit.
How many credits does Workspace AI Edit cost?
It currently costs 5 credits per edit. The button shows the actual cost before submission.
What if an AI edit changes too much?
Use a narrower prompt. Clearly state what must stay unchanged and what should be modified. For example: "Only change the title. Keep all other labels, colors, and layout unchanged."
Files and account
Where can I find previous generations?
Log in with the same account used for generation, then open My Creations.
Why did an upload or download fail?
Use common image formats such as PNG, JPG, or WebP, keep files reasonably small, and retry after refreshing. If the issue continues, follow Troubleshooting.
How do I keep account access stable?
Use the same login method and email each time. If you used a different email for payment or generation, support may need both email addresses to locate the records.
