CLUSTER KNOWLEDGE-NOTES-PERSONAL · 27 ENTRIES · EARLIEST ENTRY 2024-08-07

Personal knowledge management apps

This cluster covers personal knowledge management and note-taking tools that store, organize, and search notes, documents, bookmarks, and other saved materials. The dated history is thin: one entry in 2016‑12, then a gap until 2024‑04, followed by occasional entries through 2026‑03, which is too sparse to infer a clear growth pattern. Traction leaders by activity signal are lore, Capacities – Notes & PKM, and Chrono‑AI, all with zero stars, indicating minimal observed engagement.

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.
