A hosted web page that turns text-layer PDFs into Markdown in the browser tab using Mozilla's pdf.js: drop a file, preview, then copy or download the .md. Reverse conversion and a Batch page are also linked. Closed source, free to try, no pricing page. Note before using it: the "nothing is uploaded" claim covers the homepage workspace only, not the linked Batch page, and there is no OCR, so image-only scans come out empty.
