Summarize documents with PostgreSQL

Fires the moment a webhook arrives across PostgreSQL, Outlook and Slack, summarises long text with an AI chain. Built for social copy, around a "Read Recent from PostgreSQL" step, in 18 documented nodes.

Summarize documents with PostgreSQL and Outlook for your team. An original, ready-to-import n8n workflow built around the 'AI Summarize & Route' pattern for content creation & media. It fires on a webhook and orchestrates 18 nodes across PostgreSQL, Outlook, 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. What used to take a morning now runs on its own.

Key benefits

  • Keeps PostgreSQL and Outlook in step for social copy, without anyone re-typing a row
  • A failed PostgreSQL or Outlook call is retried rather than dropped, at any of the 18 nodes in this social-copy build
  • Every social-copy run leaves an audit row behind, alongside PostgreSQL
  • The social-copy AI step is isolated from PostgreSQL, so models swap without touching the other 18 nodes
  • Fans the same result out to Slack in the same run, for social copy

Use cases

  • Teams keeping PostgreSQL and Outlook aligned by hand for social copy
  • Pushing social-copy events into PostgreSQL and Outlook the moment they land, not on the next poll
  • Social copy work where "Read Recent from PostgreSQL" is still a manual step before PostgreSQL
  • Social copy work that only reaches PostgreSQL when a webhook arrives, 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

Advanced level

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

  • Using a Chain for fixed AI steps instead of paying for an Agent
  • Moving data between PostgreSQL, Outlook and Slack in a single run
  • Normalising timestamps before anything downstream compares them

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, Outlook, 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.
