Preserve web content permanently while organizing bookmarks through categories, tags, and custom lists with monitoring that alerts you when saved pages become unavailable. Archive links automatically via Internet Archive upon saving, search and filter bookmarks by multiple properties, switch between light and dark modes based on preferences, access everything through REST API for external integrations, control visibility by keeping archives private or sharing publicly, generate RSS feeds for links, tags, and lists, and save pages instantly with a lightweight bookmarklet instead of bulky extensions.
