Content Idea Generator (n8n)

3 post options per topic

Agencies managing social media for several clients spend hours every month coming up with post ideas that fit each client's industry, audience and rules. This workflow reads each client's brief from a Google Sheet, has GPT write three ready-to-edit post options per topic in the client's tone and within their compliance rules, and puts each idea straight onto that client's Trello backlog. The team starts the month editing drafts instead of staring at a blank page.

Feature Highlights

Account managers fill in the brief once; the workflow does the rest

  • Industry, primary service, audience, content goal, USP and call to action
  • Tone, content pillar, platform and content type
  • A compliance layer for regulated industries, such as healthcare or legal

Stack

  • n8n: Loops over clients and topics and formats the output.
  • OpenAI GPT-4o mini: Writes topics and post options from each client's brief.
  • Google Sheets: The client brief database.
  • Trello: Creates a card per idea on each client's backlog.

Use Cases

  • Social media agencies planning monthly content for many clients
  • Healthcare, legal and other regulated brands that need compliant copy
  • In-house marketing teams that want a steady supply of first drafts

How It Works

  1. The team keeps each client's brief in a Google Sheet.
  2. The workflow reads the brief and sends it to GPT with the client's rules.
  3. GPT returns a topic and three post options.
  4. Each idea is added as a card on the client's Trello backlog.
