Finding papers

The search box at the top (or /) matches words in titles, authors, abstracts, venues, tags, notes, citation keys, DOIs and arXiv ids. Every word must match, and title and author matches come first. Filters can be mixed with words:

Filter Finds
author:hinton Papers with that author
year:2019, year:2015-2020 Papers from that year or range
tag:"machine learning" Papers with that tag (quotes for spaces)
in:"Physics/QFT" Papers in that folder and the folders inside it
has:pdf, has:abstract, has:arxiv, has:notes Papers that have one
no:pdf, no:abstract, no:arxiv, no:notes Papers that lack one (no:pdf: no PDF in your storage yet)
is:starred, is:recent, is:trash Starred, recently read, or in the trash

Inside the PDFs

Once a paper's PDF has been read for search, its words are found too, with the page they are on. Papers you open are read on their own. For the rest, the list says how many haven't been read yet and offers Read them now. The text is kept in lightkone/text/ next to the library, so this happens once per paper.

Search by equation

Search by equation (side bar, Discover) finds the papers in your library that use a formula. Type it in LaTeX, for example E = mc^2 or \nabla \cdot B = 0. Lightkone reads the displayed equations from the LaTeX source that arXiv keeps for each paper, so it covers papers with an arXiv id, and it finds an equation however it was spaced, braced or named. Reading the equations of a large library takes a while the first time (arXiv asks to be read gently). It can be stopped and picked up later.

Ask your library

Ask at the top answers a question from your papers, with a Claude key. It picks the passages that bear on the question from your papers' full text and abstracts, and Claude answers citing them as [1], [2]: tap one to open that paper at that page.

New on arXiv

New on arXiv ranks each day's preprints, in the categories your library is in (or the ones you choose), by how close they are to your papers. Keywords you give lift preprints that mention them. Add the good ones with one tap.

The citation map

Citation map shows which of your papers cite which, from OpenAlex. Tap a paper to see what it cites and what cites it. Its Missing from your library tab lists the works several of your papers cite that your library doesn't have yet, most cited first. A paper's details also offer Find related for its neighbours.
