An image text remover is a tool that takes the words out of a picture and fills in what was behind them. LayerGrab does it by lifting every block of text onto its own transparent layer, so you get two things back: the picture without the text, and the text itself as separate layers.
The coffee poster on the right was split with the pre-filled instruction and nothing else. The headline, the date line and the “20% OFF” lettering came back as three text layers; the cup, the leaves and the empty red badge stayed in the background, with the gaps painted in. One thing to know: the small ornaments next to the headline and the date line went with the text, because the model counts them as part of those blocks.
