Links

Rich URL preview cards with automatic metadata fetching.

Link blocks turn URLs into rich preview cards. Paste any URL and Cobloc automatically fetches the page's title, description, image, and favicon to create a visual bookmark.

Create a link block from the block selector (or press L), then paste a URL into the input field. Cobloc fetches the Open Graph metadata from the linked page and displays it as a card.

What's displayed

A link card shows:

  • Title — the page's og:title or <title> tag
  • Description — the page's meta description or Open Graph description
  • Thumbnail — the page's og:image if available
  • Favicon — the site's icon for quick visual identification

Click anywhere on a link card to open the URL in a new browser tab.

Metadata is fetched once when the link is created. If the linked page updates its content, you can refresh the preview from the block menu.
