As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • list_disagreementsWhere the library argues with itself

    Every sentence in the library where a paper says prior work is wrong, or puts itself beside it to win. Small on purpose — disagreement is rare and concentrated, and the whole set is readable.

  • read_paperRead one paper's citations and assumptions

    Everything Keystone reads out of one arXiv paper: what it adopts, extends, disputes and measures against, and the assumptions it states with a citation, its own evidence, or nothing at all. Works for any paper on arXiv that ships LaTeX source — one outside the library is parsed on demand, which takes a few seconds. Nothing is summarised or inferred; every line is the paper's own.

  • search_librarySearch what Keystone read

    Search 2497 readings taken from 234 arXiv papers' LaTeX source: citation stances (adopts, extends, disputes, measures against) and stated assumptions. Matches on the quoted sentence, the cue phrase that decided it, and the work cited. Returns the sentence verbatim with a link to the exact line.
