piles - citation capture, rethought piles is a citation-capture tool for researchers who read papers in their browser. You highlight a passage, hit one keyboard shortcut, and piles resolves the source (DOI, bibliographic metadata) in the background using public APIs like Crossref. Export to BibTeX for Zotero, Citavi, or any reference manager. It is the capture layer before your library, not a replacement for one. How it works

Open a paper in your browser, where you already read.

Highlight the passage worth keeping.

Hit one shortcut (or right-click and choose "Add to Piles"). No forms, no tagging.
