CLUSTER KNOWLEDGE-NOTES-FIRST · 25 ENTRIES · EARLIEST ENTRY 2026-09-02
Local-first Markdown knowledge tools
This cluster comprises local-first Markdown knowledge management tools that share features like wikilinks, backlinks, search, and graph views. The dated history is too thin to read a shape from, as only three dated entries exist before the index start. Orrerium leads on traction with 7 stars, while other members have 0 stars.
Entry timeline
ENTRY TIMELINE
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.
