CLUSTER KNOWLEDGE-BASE-MARKDOWN · 11 ENTRIES · EARLIEST ENTRY 2026-09-29

Local Markdown knowledge bases

This cluster consists of local-first knowledge base applications that store notes as Markdown (some also HTML) files, offering search, knowledge graphs, and optional AI chat or AI-session linking. The cluster's dated history before the index start is too thin to read a shape from—it predates the index or its members are undated. Among traction leaders, weave shows the highest activity signal, followed by MemoCosmos and knemora.

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.
