About Costarium
What is Costarium?
Costarium is a visual bookmark manager that organizes saved links as stars within orbital core systems.
What Costarium does
Costarium organizes articles, tools, videos, and resources in a visual workspace where useful links stay active and unused links fade away. It provides revisit reminders, Telegram bot link capture, a black hole to delete stars, and search filters.
Who Costarium is for
For people organizing articles, tools, videos, and resources who want to save links and bookmarks they actually revisit.
How Costarium works
Users add links that appear as stars within cores, or send URLs to @costarium_bot on Telegram. Frequent visits keep stars active, inactive bookmarks collapse automatically, and dragging a star into the black hole removes it.
Key features
- Visual orbital mapping where bookmarks appear as stars organized around cores.
- Automated decay and self-cleaning where frequently used links stay active while unvisited links fade away.
- Revisit reminders that surface saved resources before they are forgotten.
- Telegram bot integration via @costarium_bot for saving links directly into collections.
- Black hole function where dragging any star into the black hole deletes it.
- Color-code and tag links to find them fast with quick search and filters.
