Real pixels.
A little browser magic.

Grounding DINO locates poster, flyer and notice candidates. OpenCV searches for repeated copies, and visual comparison keeps one crop per design. Every remaining box can be edited, removed or supplemented with Add box.

Detection runs in your browser. Its first use downloads about 204 MB of model weights, which are cached. Refine uses the smaller SlimSAM model for optional silhouette editing.

This is a prototype: check the crops. Low-confidence detections are retained for review, and hidden duplicates can be restored. Curved or partly hidden paper may need manual adjustment.

Detection and cutting run on this device. Small poster crops are sent through the local backend to Gemini to read the event; the original photo is not uploaded. This PoC does not publish events or award rarity. Shiny and Gold require a verified collector record; otherwise the finish is an unverified Standard preview. Your deck is saved in this browser only. It is not synced to your account. The original artwork is preserved underneath the finish. Camera preview needs HTTPS or localhost; the take-photo picker is available as a fallback. The demo photo is AI-generated; the other two scenes are synthetic test images.
