CLUSTER END-NOTE-NOTES · 32 ENTRIES · EARLIEST ENTRY 2026-07-06
Encrypted note-taking apps
This cluster comprises privacy-focused note-taking apps that emphasize end-to-end encryption, local-first storage, and cross-device sync. Dated entries span from 2019 to 2026, appearing irregularly with minor concentrations in August 2025 and March 2026, though the overall pattern is thin. Memodo has the highest traction signal (1 star), while Notesnook and Anytype follow with 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.
