Import from Substack

Your agent can bring Substack into Curation Space three ways. It can curate the posts you've saved, connect the publications you read so their new posts keep arriving, and, if you write on Substack, gather the links you've shared in your own posts.

How do I import my saved Substack posts?

  1. Connect your agent to Curation Space

    Copy the prompt in How do I connect my agent? into Claude Code, Codex, OpenCode, or another agent that supports MCP, and sign in when it asks.

  2. Let it see your saved posts

    If your agent can use a browser, such as Claude in Chrome, sign in to Substack there. Your saved posts are under Saved at substack.com/inbox/saved.

  3. Ask it to curate them

    Paste a prompt like the one below.

Open my saved posts on Substack and curate them into Curation Space.

Group them into private curations by topic, and give each curation a short, clear title. Before adding anything, show me the curations you'd make and how many posts would go in each, and wait for my go-ahead. Then add them, newest first. Don't write notes; I'll add my own.

How do I bring in the publications I read?

Ask your agent to connect each publication to a curation as an Input Source. From then on, every new post is added within about 15 minutes, without your agent. A curation can have up to 10 Input Sources, so grouping publications by topic lets one curation gather several.

Open my Substack subscriptions at substack.com/inbox and list the publications I read. Suggest private Curation Space curations that group them by topic, at most 10 publications each, and wait for my go-ahead. Then connect each publication's feed to its curation as an input source, quietly importing its latest 20 posts.

Posts the agent quietly imports aren't delivered to anyone as new links. Posts published afterwards are.

How do I gather the links from my own posts?

Export your posts from your publication's settings, attach the download, and ask:

These are my Substack posts. Collect every link I've shared in them into a private Curation Space curation called "Linked from my newsletter", newest post first. Use the sentence each link appears in as its note.

A link you've shared in several posts is added once.

Will my followers be sent every post?

No, as long as the curations are private while your agent adds links, which the prompts ask for. Links added to a private curation never reach your followers as new links, even after you make it public.
