How Vaultmark works, for creators and buyers.

What Vaultmark is

Vaultmark is a marketplace for digital files — print files, 3D models, and PDFs — built around a Preview → Pay → Download flow. Buyers preview a watermarked version freely; the original file is released only after a verified payment.

How the secure flow works

  1. Every product has a public preview and a private master. The master is never given a public URL.
  2. A buyer pays through Stripe Checkout.
  3. Stripe sends a signed webhook to our server, which verifies it and unlocks the order.
  4. The buyer gets a short-lived, capped download link to the master. The link expires and is limited in uses.

See the glossary for the concepts in detail.

For creators

  • Create a product in the studio — the AI can draft your title, summary, tags, and category from a short description.
  • Add files by uploading, generating with AI (photo, video, 3D, PDF), or building an image in the editor.
  • Generate a preview automatically from your master (downscaled + watermarked images, or stamped PDF pages).
  • Publish once a master file is attached. Products can be draft, private, or published.

For buyers

  • Preview any published product before buying.
  • Check out as a guest or signed in; your purchases appear under your orders.
  • Download within the link's window and usage limit.
