Anytype is an offline-first note-taking and collaboration platform built by a Swiss non-profit (Any association). It features a block-based editor and database-like structure (with templates and widgets). All data is stored locally on the user’s device (no central servers) and can sync peer-to-peer across the local network. According to the site, Anytype provides “absolute data privacy” – data is end-to-end encrypted and “owned by you” (users hold the encryption keys).
