I have a 2019 Samsung Galaxy device.If she had a Galaxy S23, she could do that. Scanning and text extraction is in the camera app and I think they are rolling it out to older models too. Just need to go to the Galaxy Store app and install updates.
It can do this, too. You open the Camera, aim at a document, it detects it's a document and you tap the scan button. It auto-crops it, and then when you open the scan you just took, it has a little "eye" icon at the top right, which you click to show more details, and one of the options is "text." You can select text right in the app–and of course can share it and all that.
