The mask is the product.
Automatic cut-outs estimate which pixels belong to the subject and build a mask around them. The hard part is not the middle of the object, it is the edge.
Smart / Local Tools
Blur a background by depth.
Estimate scene depth locally, choose the distance you want to keep sharp, then soften areas farther from that focus range.
Private by design: your image stays in this browser tab. The open depth model downloads on first use and runs locally on your device.
Useful to know
Four things worth knowing.
Edges are where it fails.
Hair, fur, glass, smoke, shadows, reflections and thin objects are where automatic masks are most likely to guess wrong.
Check light and dark backgrounds.
Automatic results still need a human check around edges, text, faces and small details.
Keep the original layer.
Check the result on both a light and dark background. A halo that disappears on white can be obvious on black.
