I. The profile

What it aims at

Everything downstream is aimed by your centroid, a single construction of your scientific interests, which exists in high-dimensional space. Curator holds one of these per person. Which papers are considered and recommended is decided by how close they sit to it.

SourcesWhat that construction is built from

Source	Where it comes from
Your pins	Your pins are the core of your feed. What you save, before and after pinning, moves it a little from there; it never moves past your pins. Pin any paper — yours or anyone’s — from the paper menu or Feed calibration.
Your own papers	Publications matched to you, usually via ORCID at sign-up.
Your saves	Your most recent saves, once there are ten or more and they agree with each other. Papers imported from Zotero do not count here, and they do not nudge a pinned anchor either — pinning a paper from your import is how to make it count.
Your topics	The subjects you chose during sign-up, used until either of the above exists.

II. The shortlist

What is eligible

Only papers published in the last 90 days are eligible. Within that window Curator runs six searches separately rather than ranking one big list: flagship journals, established journals, journals it knows little about, preprints, whatever readers are engaging with right now, and a safety net over everything recent. Each contributes its own best matches, so the shortlist has range every time, for everyone.

Each search is held to its own standard, and the standard is deliberately hardest on the least familiar venues. A flagship paper is admitted on a looser match, because you probably want to know either way; a paper from a journal Curator has never heard of has to be a far closer fit to earn its slot.

Never eligible

You handled itSaved, skipped, noted, marked read, commented on, or sent to someone. Any of these retires the paper from your feed permanently.
You wrote itPapers matched to you as an author are excluded. Your feed is not for telling you about your own work.
You muted itA muted journal is removed outright, from every search, and anything from it already waiting in your deck goes with it.

III. The ranking

What wins

Every eligible paper is scored as a match against your profile, adjusted by a handful of signals. Two rules then sit outside the score: no journal takes more than two places in a deck, and two places are reserved for papers readers are engaging with right now.

The signalsWhat the score is made of — named, not weighted

FitMatchHow close the paper sits to your profile, and to the centre of the work you have published yourself.

FreshnessAgeNewer papers rank higher, on a gentle curve across the ninety-day window.

ImpactReaders’ reviewsThe Impact score readers have posted on the paper — the strongest signal in this list. A paper nobody has reviewed is neutral.

VenueJournalHow the journal is rated — plus anything you have boosted by hand.

Your skipsWhat you passed onPapers that resemble ones you skipped in the last month are pushed down — never out.

Community interestReachWhat other readers are doing with a paper right now — commenting, saving, recommending — earns it one of the two reserved places. Citations play no part anywhere.

Q and ITwo scores on every card

Score	The question it answers	Where it comes from
Q — Quality	Do the experiments support the words?	Readers’ Quality reviews, 1 to 10
I — Impact	Should other people read this?	Readers’ Impact reviews, 1 to 10

Until someone has reviewed a paper both read N/A, and the card carries a journal-brand estimate in italics beside the journal name instead — a guess from the journal’s impact factor, which Curator’s own numbers replace as reviews accumulate.

Spatial niches of stem-like CD8⁺ T cells predict checkpoint response

Adeyemi, Bhatt, …, Okonkwo, Zhang

Checkpoint blockade fails in most solid tumors, and no pre-treatment marker reliably separates responders from non-responders. Here we map stem-like TCF1⁺ CD8⁺ T cells across 214 tumor-draining lymph nodes and show that their spatial organization — not their abundance — predicts response…

What each button does

Skip clears it and steers your feed away from papers like it. Note files it under Noted in your Library and clears it, with no effect on ranking. Save keeps it and steers your feed toward more like it. Send puts it in front of a colleague or a group, and appears once you belong to one.
