What a useful tool! Right now I scan my documents using VueScan, which can add an OCR layer to PDFs automatically, but that only works if I have a physical document — I am out of luck if I want to add OCR to an existing PDF. This tool looks like it can help.

I have some notary documents from when I bought a house. Searching through it manually is a hell, not only because notaries use obscure language and the document is huge, but also because they format the document in a way that's safe against edits. I have longed for a way to Ctrl-F it.
