An n8n + Groq AI workflow that turns one topic into five platform-ready content pieces — blog post, Instagram caption, LinkedIn post, Twitter/X thread, and email newsletter — then publishes to Notion, logs to Google Sheets, sends via Gmail, and alerts the team on Slack. 20 nodes. 8 apps. One webhook. Zero manual work.

How it works

Trigger

Webhook topic submit

Submit a single topic via webhook — the workflow immediately responds with confirmation and begins processing.

Format

Input normalization

Formatter cleans the topic, strips noise, and structures it for consistent AI prompt injection across all five channels.

AI Generation

5 parallel Groq calls

One topic fans out into five platform-specific content pieces simultaneously — blog, Instagram, LinkedIn, Twitter/X, and newsletter — each tuned to channel voice and length.

Merge & Code

Aggregate & transform

All AI outputs merge into one structured payload. A JavaScript code node reformats and enriches data before downstream delivery.

Publish & Log

Notion + Sheets

Content is published as a new Notion database page for editorial tracking and appended to Google Sheets for audit and reporting.

Deliver & Notify

Gmail + Slack

Newsletter sent via Gmail, team alerted on Slack. A conditional branch triggers a review workflow if human approval is needed.

Proof of build

⬢

20-node n8n workflow with 5 parallel AI branches

Webhook receives topic → responds → formats input → splits into 5 concurrent Groq AI nodes (Blog, Instagram, LinkedIn, Twitter, Newsletter) → merges results → JavaScript transform → publishes to Notion → logs to Google Sheets → sends newsletter via Gmail → alerts team on Slack → conditional review branch.

5 parallel AI content generation calls via Groq — zero wait time between outputs

8 integrated apps: Webhook, Groq, JavaScript, Notion, Google Sheets, Gmail, Slack, If

Review branch: If flagged, routes to Gmail + Slack review queue; otherwise posts skip notification

One webhook trigger → full multi-channel content pipeline → complete in under 30 seconds
