Photograph any jigsaw piece and Piece Finder shows you exactly where it belongs on the box art — matched two ways by classical and deep computer vision, without your photos ever leaving your machine.
These are real pieces from a real puzzle, located by the actual matching pipeline — green is SIFT's projected outline, amber is LoFTR's deep-match region.
No account, no cloud, no training data — the models are pretrained and run on your CPU.
Box art or the finished picture. It's indexed once — thousands of visual landmarks, cached and ready.
On the table, in your hand, any background — a U2-Net segmenter cuts the piece out automatically.
Two independent matchers point at the spot, with confidence scores and a zoomable outline on the picture.
A sky piece and a castle piece are different problems. Piece Finder runs both matchers side by side and shows every candidate.
Rotation- and scale-invariant features with RANSAC verification — a precise, provable outline for textured pieces.
Dense deep matching that still works on sky, water and other low-texture pieces where keypoints starve.
Cuts the piece from any background before matching, so your photo doesn't need a studio setup.
The last stretch of every puzzle is a hunt. Make it a photo instead.
