Do I need to know how to code?

No. You describe what you want in plain English—something like "scrape the top AI newsletters on Substack weekly and put the results in a Google Sheet"—and Twin builds the agent. No code, no configuration files.

Can my Substack agent run on a schedule?

Agents can be set to run on a recurring schedule—daily, weekly, or at whatever cadence fits your workflow. The "Weekly Digest IA" and "AI Newsletter → X Posts" agents both run this way, pulling fresh Substack data each cycle without manual triggering.

Which Substack publications can Twin access?

Twin reads publicly visible Substack pages through the browser. Any publication whose posts are accessible without a paid subscription can be scraped. Paywalled post content requires an active subscription in the connected browser session.

How does Twin get data out of Substack if there's no API?

Twin drives a real browser, navigating to Substack pages, reading the visible content, and extracting structured fields like titles, dates, and links. The results can be written to Google Sheets, Google Docs, or passed to another step in the workflow.

How it works

Three steps from idea to a running Substack agent.

1

Twin logs in to Substack

Twin opens a private browser session on your behalf and authenticates to Substack just like you would.
2

Describe the workflow

Tell Twin what you want done in Substack in plain English — including any flow that has no public API.
3

Twin runs in your browser session

The agent operates Substack step by step, handling forms, modals, and dashboards exactly as a human would.

Why Twin for Substack

What makes Twin a better fit than a generic automation tool.

No public API to work around

Substack does not expose a structured public API for newsletter discovery or post data. Twin operates the browser directly, reading pages the same way a person would—so you get the data without building custom scrapers.

Manual copying breaks workflows

Pulling post titles, links, and summaries by hand creates stale data and missed follow-ups. Twin runs the same extraction steps on a schedule and writes results directly to Sheets or Docs, keeping records current.

Works across any Substack publication

Because Twin navigates browser pages rather than relying on an authenticated API connection, it can read any publicly visible Substack publication—not just ones you own or follow.
