Go to Habla.news and check it out! Habla is long-form (editable) blogging over Nostr. So you log in with your nsec (via an extension like Nos2x I’d suggest).
As built it already models most of the functionality of medium - bold, italics, underline, blowout quote, links / code. As it develops I’m sure additional more unique functionality will be added.
Publishing happens over relays that support the long-note NIP.
#[3] is HablaDev so he’s a great person to reference with questions and feedback - though other knowledgeable people will always jump in to help too 😅
