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 Cursor, Claude Code, or Codex to read your live library. After purchase you paste one message into the agent and it registers the library. The PDF does not need this — its first pages are a prompt you attach with the file.
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.
