CLUSTER KNOWLEDGE-NOTE-TAKING · 10 ENTRIES · EARLIEST ENTRY 2026-08-04

Self-hosted AI note-taking apps

This cluster covers self-hosted, AI-assisted note-taking and personal knowledge-management apps, with features like semantic search, summaries, tasks, chat, cloud sync, realtime collaborative editing, and rich blocks. Its dated pre-index history shows one entry in February 2024, one in May 2024, then a gap before two entries in April 2026, one in May 2026, and one in June 2026. AstralNotes-Android is the traction leader at 6 stars, while obsidian-vault-kit and tachles-open-source each have 1 star.

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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 10 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
