CLUSTER SIDE-PLUGIN-READING · 7 ENTRIES · EARLIEST ENTRY 2025-09-15

Zotero bilingual PDF readers

This cluster consists of Zotero plugins that enhance academic PDF reading, primarily through bilingual side-by-side translation with sentence-level highlighting, figure translation, and resume support, plus one plugin that presents documents line-by-line for focused reading. The cluster's dated history is too thin to read a shape from—it predates the index or its members are undated. Among traction leaders, zusia leads with 11 stars, while Zotero_PDF_Bookmarks and zotero-bilingual-reader each have 1 star.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
