## Detailed info

## 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.
