Costarium vs Kyurations

Costarium offers a beautiful and frictionless way to build a cosmos of links. Users can create core stars, which are categories around which they save their links, and add links as stars with titles, tags, and colors. The platform also integrates with Telegram for easy link saving through the costarium_bot. Users can manage their links, revisit important information, and expand their cosmos with reminders and important links.

Best for: Individuals and teams looking to organize and manage links and knowledge efficiently.

Everyone has that one friend. Mine's in a group chat of six. He sends maybe two links a week, far fewer than anyone else, and I open both without checking the preview.

What he does is real work and nobody sees it. He reads for hours, throws away almost all of it, sends the two that survived. Then WhatsApp eats it. Ask him for the new food place in Bangalore that he shared or that blog post about building agents and we're both scrolling for ten minutes.

That job got harder fast. Three quarters of new web pages now have machine-written text in them, not because writers went away but because every writer picked up an engine. Output went vertical. Nobody's day got longer.

So we built Kyurations.

It lives where you already read. Chrome extension, Instagram DMs, X bookmarks, WhatsApp, MCP. You're scrolling, something lands, you send it across, you keep scrolling. No folders, no tags, no naming things. It piles into one place, your Bower, and the AI takes the boring half. Pulls the article, writes the summary, sorts the pile into lists. You can talk to the whole collection and it answers from what you saved, with citations.

Those lists become newsletters. Someone subscribes to your reading on a topic and it lands in their inbox without you writing anything. When a batch is ready you get a message, glance at it, drop what doesn't belong, and it goes.

Here's the part I'm proudest of, and it's a strange thing to brag about: you never have to open it. Nobody visits their solar panel. The collection builds while you get on with your day, and six months in you own something. People subscribe to it. You can sell it. It leaves with you if you go.

One rule we won't break. The AI never picks what goes in. It arranges, you choose. The second a machine decides what's good, this becomes another feed, and there are enough of those.

Happy Kyurating!
