Browser research capture extensions

The cluster comprises browser extensions that convert highlighted web content into structured notes, summaries, citations, or direct exports to tools like Notion, primarily serving research and data-entry workflows. Dated entries before the index start are sparse but present: one in 2022-06, one in 2025-08, and three in mid-2026 (one in 06, two in 07), with the sparse pattern making any shape hard to read beyond occasional releases. The traction leader is paper-library-checker with 102 stars, while browserops-capture and context-lens each have zero 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.
