The Hypothes.is plugin enables users to synchronize their web article highlights and annotations from the Hypothes.is platform directly into their Obsidian Vault. Highlights are synced on startup or manually triggered, with options to update existing entries when new annotations are added. Users can customize the format of highlights using Nunjucks templates and organize synced files by domain or folder location. Additional features include group management, auto-sync intervals, and manual resyncing of deleted files. This plugin is ideal for integrating web-based annotations into a centralized knowledge management system.
