Made by creators, for creators.
Ghostly comes from 3MF Labs, a small shop that designs and sells 3D print files.
We wanted a simple way to prove a file is ours and to see which copy got shared, without changing how anything looks or prints. So we built one, and we used it on our own files first.
It started as an internal tool. The more we tested it on real models, the clearer it became that every independent designer should have the same thing: a quiet signature in every file they sell, and a plain answer when they find a copy.
That's Ghostly. It's still small and we're opening it carefully, a few creators at a time.
What we hold ourselves to.
Your files print the same
Every signed copy is checked against your original. If it would print differently, the hidden part is left out.
We say what it does, not how
We're open about what Ghostly can and can't do. The method stays private, because that's what keeps it working.
No overpromising
Ghostly proves a copy is yours. It doesn't stop copying, and we'll never say it does.
Your work stays yours
Your files are used to sign and recognize your designs. They're never shared or sold.
