FAQ

Is this a subscription?
No. Both the PDF and the live library are one-time payments.
What’s the difference between PDF and live library?
The PDF freezes on the day you buy — you get a generated snapshot of every study published at that moment, and that file never gains new studies. The live library is the same evidence as a searchable library for your AI agent, and it keeps growing as new studies are added.
What’s an MCP?
A way for AI tools like Cursor or Claude to call your live library. After purchase you get a URL and access key to paste into your agent. You don’t need to know the protocol to use the PDF.
How do I get the files? Can I get a refund?
Delivery is by email within seconds of payment. If the email doesn’t arrive, reply and we fix it. Digital goods are delivered immediately, so there is no refund after successful delivery.
