Known limitations
Written down because finding them yourself, halfway through a search, is worse.
The searching
200 records by default, not everything PubMed found. The count says how many matched; the app downloads the first slice of them, most recent first. Raise Max records to download in the sidebar if you need more, but a search that returns four thousand results is usually a search worth narrowing instead.
The filters on the results do not go back to PubMed. They narrow what was already downloaded. If a paper was outside the first 200, no filter here will find it.
Blocks are two levels, not a syntax tree. Wordings inside a block, blocks between themselves. (A OR B) AND (C OR (D AND E)) cannot be drawn — write it by hand on one line instead, which the app accepts as it is.
PubMed reads operators left to right. It does not give AND precedence over OR the way a programming language would. Each block gets its own brackets for exactly this reason, but a hand-written line is your own responsibility.
The journals
SJR is not the Journal Impact Factor. The impact factor is Clarivate's, from the JCR, and is not in any file here. SCImago gives SJR — citations weighted by the prestige of the journals making them — and cites/doc (2y), computed like an impact factor but over Scopus. Both are shown and both are labelled.
About one article in ten has no quartile, because its journal is not in SCImago at all: Cureus, medRxiv, most case-report journals. They show nothing rather than a wrong badge.
Matching is by ISSN only, plus an exact title match as a fallback. Fuzzy title matching would raise the hit rate by a percent and would occasionally give an article the quartile of a different journal with a similar name. A wrong quartile is worse than no quartile.
The writing
The article structures and the linter rules are a transcription. They were copied from Radiopaedia's published guidance on 2026-08-04. When theirs change, this is an old copy until someone redoes it.
The linter runs on the draft, not on the published article. It cannot see what their server would say about images, tags or links.
Citations are resolved through radiopaedia.work/cite, which is not ours. If it is down, citations stay unresolved — the draft is unaffected.
The app itself
One person at a time. It serves a page to your own browser on localhost. There is no login and no sharing; two people cannot screen the same archive.
No undo. Deleting a list, a draft or an article is immediate. The backup in the sidebar is the undo.
Articles marked read are purged at startup, and their PMIDs remembered so they do not come back in a later search. An article in a reading list is never purged.
