Produce blog drafts with PostgreSQL & Slack

Runs on a schedule across PostgreSQL and Slack, hands the decision to an AI agent with its own tools, then branches on the check before anything is written. Built for listening, around a "Stamp & Shape Post" step, in 19 documented nodes.

Produce blog drafts with PostgreSQL and Slack without manual work. An original, ready-to-import n8n workflow built around the 'Content Generation' pattern for marketing & advertising. It runs on a schedule and orchestrates 19 nodes across PostgreSQL, Slack. 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 PostgreSQL and Slack in step for listening, without anyone re-typing a row
  • A failed PostgreSQL or Slack call is retried rather than dropped, at any of the 19 nodes in this listening build
  • The listening AI step is isolated from PostgreSQL, so models swap without touching the other 19 nodes
  • Pinned sample data ships with it — run all 19 nodes for listening before wiring PostgreSQL
  • 19 nodes, each with a doc card explaining what it does for listening

Use cases

  • Teams keeping PostgreSQL and Slack aligned by hand for listening
  • Listening work that needs a judgement call per item before it reaches PostgreSQL
  • Listening work where "Stamp & Shape Post" is still a manual step before PostgreSQL
  • Listening work that only reaches PostgreSQL on a schedule, when someone remembers to start it

Agent tools included (3)

An AI Agent is only as capable as the tools wired into it. These are read from the template's own graph — every one is a real node in the file you download.

  • Draft Specialist (Sub-workflow) · Another n8n workflow
  • Research Specialist (Sub-workflow) · Another n8n workflow
  • Review Specialist (Sub-workflow) · Another n8n workflow

This agent runs without conversation memory - each run starts from the incoming request.

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

Advanced level

Adds branching depth and audit logging on top of the core pattern.

  • Chaining a writer pass and a separate critic pass for better output
  • Publishing as a draft so a human stays the final gate
  • Moving data between PostgreSQL and Slack in a single run

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 (PostgreSQL, Slack). 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.
