Preview shared links while writing your post

See a link’s preview image, title, and description inside the post editor, including links to Buildside pages.

What’s changed

• Paste or type a web address to load its preview before publishing. Buildside links and addresses without https:// work too.
• A loading card shows a spinner and Loading preview while metadata is fetched. Replacing or removing a link clears the old preview.
• If a site cannot provide metadata, the link remains available with a domain preview.
