Stamp & reveal
Where Embed hides a machine-readable text ID, Stamp hides a visual mark — a logo — that stays invisible until deliberately amplified into view. Think of it as an invisible rubber stamp.
Stamp
- Drop the image to protect into the Stamp panel.
- Provide the logo image to stamp with.
- Download the stamped result — to the eye, it's identical to the original.
Note
Stamping spends 1 gas per image (members: unlimited). Revealing a stamp is free.
Reveal preview
Drop a stamped image into Reveal preview and HILIA amplifies the hidden differences until the stamp shows. The Gain control sets how hard to push — raise it if the stamp is faint, lower it if the preview washes out. The preview is approximate by design: it's a human check, not a forensic measurement.
When to use Stamp vs Embed
| You want to… | Use |
|---|---|
| Prove ownership with a visual mark a human can see on demand | Stamp |
| Tag images with a machine-readable ID (client, order, batch) | Embed |
| Scan images in bulk, or via the API | Embed + Detect |
They compose: you can stamp an image and embed a text ID in it.
