CLUSTER ACADEMIC-ANOTHER-LANGUAGE · 13 ENTRIES · EARLIEST ENTRY 2026-08-17

PDF translation tools

The cluster consists of tools that translate PDF documents, especially academic papers, into other languages for reading and research. The dated history before the index start is too thin to read a shape from—only one dated entry exists, so the cluster predates the index or its members are undated. Traction leaders by activity signal are OceanPDF (13 stars), PaperLens (5 stars), and oh-my-paper (2 stars).

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.
