Here is a work-in-progress tool for that: https://npub.pro/import-ghost

You can bring articles from your Ghost site to Nostr and make them accessible for people here to zap/react/comment.

Eventually the tool will let you copy all website settings from Ghost to an npub.pro site. For now - content only.

Ghost is great, but nothing beats adding your cryptographic signature to your article and broadcasting it to an open interoperable network, right?!

P.S. A reminder about a similar tool for Twitter: https://exit.pub
