A one-time purchase of a single digital file, DESIGN.md ("Convergence"). It is delivered electronically immediately after payment is confirmed. There is no account, no subscription, and no recurring charge.
The price is shown at checkout in USD and charged once. Payment is processed by Stripe; GoodAiUX never sees or stores your card details. Applicable taxes, if any, are shown by Stripe before you pay.
After a successful payment you are redirected to a download page and the file downloads automatically. The download link remains valid for 24 hours; your Stripe receipt email also contains a link back to it. If you cannot retrieve the file, email hi@goodaiux.com and we will deliver it directly.
This is a digital product delivered instantly. If the file fails to deliver or is materially not as described, contact hi@goodaiux.com within 14 days and we will make it right.
Your purchase grants you a perpetual licence to use DESIGN.md in your own and your clients' projects. You may not resell or redistribute the file itself as a standalone product. The cited works referenced inside remain the property of their respective authors and publishers.
The file is provided "as is". It is an opinionated synthesis of publicly available UX and CRO research, not professional advice, and is offered without warranty of any kind. GoodAiUX is an independent project, not affiliated with any UX research organisation or design system.
