Costarium
The spatial bookmarking system that cleans itself
Costarium helps you capture links, organize them into star systems, and revisit them with reminders.
Organize articles, tools, videos, and resources in a visual workspace where useful links stay active, forgotten ones fade away, and old clutter cleans itself automatically. Normal bookmarks and read-later apps are passive landfills. Saved links disappear inside bookmarks and become hard to find again. Open tabs pile up because you’re afraid you’ll lose something important. Endless pages of links become messy and impossible to revisit later.
