The Trick

One small digit — inserted at exactly the right place in a Hacker News URL — turns a forgettable blue link into a rich card with a headline, a snippet, and an image. That digit is 1, and that is the whole of it.

For Everyone Else

On Discord, Twitter, Teams, iMessage, Bluesky, or anywhere OpenGraph is honored, simply hand-edit the URL: insert a 1 after ycombinator. That is the entire interface.

For instance, https://news.ycombinator1.com/item?id=30167605 renders as a proper preview where the unmodified link would not.

Privacy, Plumbing & Provenance

The service is hosted on Vercel and powered by the official Hacker News API. Source is on GitHub — modest in size, modest in ambition.

Requests pass through Vercel; logs persist for one hour as part of their free plan. Aggregate metrics — request counts, error codes — are kept longer but contain no personal data we can find.
