Video, every frame cut

Drop an MP4, MOV or WebM. Every frame is cut, the text is composited behind the subject on all of them, and an exponential moving average carries the alpha forward so edges stop crawling between frames.

Salient detection

Answers "what is the subject". Right for a portrait or a product shot.

A single concrete house standing alone in fog — one clear subject

Depth mode

Answers "what is near". Everything closer than the cutoff occludes the text.

An aerial construction site with objects scattered at many distances

Paint by hand

Answers neither question. You mark exactly what goes in front — and it needs no download.

A hillside that recedes into fog as one continuous surface
A dark terrain map with labelled markers pinned across it
