Generate blog drafts: Slack for captions

Runs on a schedule across Slack, Airtable and Google Sheets, runs the text through an AI chain, then reads the feed and keeps only what is new. Built for captions, around a "Read Source Feed" step, in 22 documented nodes.

Generate blog drafts with Airtable and Slack at scale. An original, ready-to-import n8n workflow built around the 'Content Generation' pattern for content creation & media. It runs on a schedule and orchestrates 22 nodes across Slack, Airtable, Google Sheets. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Nothing slips through the cracks.

Key benefits

  • ✓Keeps Slack and Airtable in step for captions, without anyone re-typing a row
  • ✓Safe to re-run: records already in Slack or Airtable are skipped, across all 22 nodes of this captions build
  • ✓A failed Slack or Airtable call is retried rather than dropped, at any of the 22 nodes in this captions build
  • ✓The captions AI step is isolated from Slack, so models swap without touching the other 22 nodes
  • ✓Fans the same result out to Google Sheets in the same run, for captions

Use cases

  • →Teams keeping Slack and Airtable aligned by hand for captions
  • →Captions work where "Read Source Feed" is still a manual step before Slack
  • →Captions work that only reaches Slack on a schedule, when someone remembers to start it

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Production level

Production-grade: idempotency, dead-letter handling, and reconciliation included.

  • •Chaining a writer pass and a separate critic pass for better output
  • •Moving data between Slack, Google Sheets and Airtable in a single run
  • •Adding retries and an explicit error path to external calls

Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.

Common questions

What exactly do I get?

The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.

How do I import it into n8n?

In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.

Do I need anything else for it to work?

You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Slack, Airtable, Google Sheets, HTTP / REST API). No coding is required.

What if it doesn't work for me?

If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.

Can I modify or resell it?

You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
