What this is actually doing.
This runs a focused automated pass in the browser so you can inspect the result instead of handing the whole job to a larger app.
Smart / Local Tools
Generate a depth map from an image.
Create a grayscale estimate of scene depth for parallax, masking, compositing, reference and 3D-style effects.
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.
Where it stops.
It solves the named job, not every problem around it.
What to inspect.
Automatic results still need a human check around edges, text, faces and small details.
Worth knowing.
Keep the original until the finished result has worked in the place you made it for.
