Frequently asked

How are credits counted?
Each AI operation (drafting a section, generating an abstract, refining a paragraph) costs credits proportional to the model used and the length of the output. Most users finish a full chapter on a few hundred credits. Unused credits do not roll over to the next month.
Do I own what I write?
Yes — every manuscript, citation, and exported file you produce on Quilpen is yours. We do not claim copyright over your work, and we do not train models on your content.
Can I cancel or change plans anytime?
Yes. Cancel or switch tiers from your account page. Cancellations stop future billing; you keep access until the end of the current paid period. Upgrades take effect immediately and are prorated.
Refunds?
First-time paid subscribers (Starter or Pro) can request a full refund within 14 days. See our refund policy.
Who handles payments?
Payments are processed by Paddle, our Merchant of Record. Paddle handles billing, taxes (VAT, sales tax), and invoicing in 200+ countries.
Discounts for students?
Yes — drop us a note from your university email at support@quilpen.com and we will share the student rate.
