What makes Substack different
Substack publishes no view or open counts anywhere public, so the only honest measure of a post is its engagement against the subscriber count it had when it went out — and that is exactly what Mysocial snapshots. It is also the one platform where the whole essay is the content: an assistant reads the full text of every free post and Note, not a caption beside a video. Restacks are the distribution signal worth watching; a post that was restacked travelled beyond your own list, and a post that was merely liked did not.
Why Claude
Claude's remote connectors work across web, desktop and mobile, so you can ask about your connected channels from the client that suits you. Claude also supports Skills, so the Mysocial workflows — drafting a next post, researching your market, keeping brand docs current — install alongside the connector rather than being prompts you have to remember.
What to ask Claude once your posts and Notes are connected
- “Which of my posts were restacked most, and what did they have in common?”
- “Compare how my Notes perform against my full newsletter posts over the last 90 days.”
- “Which essays pulled comments rather than just likes?”
- “What have I been writing about in Notes that never became a full post?”
None of these are answerable from a screenshot or a pasted export. They need your whole catalogue, and they need Claude to know what typical looks like for you specifically.
Free versus paid
Free gives your assistant the record. Paid gives it the understanding. The line is provenance, not a quota: what Substack already reports about you is free to read. What Mysocial's own pipeline produced — transcribing, ingesting, analysing — is paid.

Questions
How do I connect Substack to Claude?
Connect your Substack account to Mysocial, then select Add to Claude, review the prefilled details, and approve access. Claude can then read your Substack posts, metrics and comments directly — no exports and no copy-paste.
Is it free to connect Substack to Claude?
Connecting is free, and so is reading what Substack itself reports — your posts and captions, view, like and comment counts, follower history and measured audience demographics. What Mysocial's own pipeline produces is paid: video transcripts, the comment text itself, audience psychographics, Hit DNA and Creator Universe research.
What can Claude actually see?
Only the channels you connect, and only what you approve. Mysocial relays your newsletter posts and Notes with their full text, reaction, comment and restack counts, and subscriber history. It cannot post on your behalf and it cannot see accounts you have not connected.
Does this work with other AI assistants?
Yes. Mysocial is a standard Model Context Protocol server, so the same URL works with Claude, ChatGPT, Claude Code, Codex and any other MCP client.
