Automated LinkedIn Posts: n8n + Gemini Schedule & Publish

Automatically generate and publish your weekday LinkedIn posts with n8n + Google Gemini

This n8n workflow schedules itself every weekday at 9am, uses Google Gemini to generate a structured LinkedIn post in your defined style, and then publishes it to your LinkedIn profile as a public post—hands-free.

What this workflow does

• Runs automatically on a schedule (weekday cadence at 9am). Review the schedule rule to match your timezone and desired posting timing.
• Prompts an n8n AI agent to select a timely topic for the current date and draft a LinkedIn post using your personal writing style.
• Generates content with Google Gemini (configured model: gemini-3.1-flash-lite) and returns structured fields including topic, post, and engagement_plan.
• Publishes the generated post to LinkedIn with public visibility, targeting your LinkedIn profile via the configured person URN.

Use cases

• For SaaS operators who want consistent thought leadership without manual writing every day.
• For automation engineers building reliable content pipelines on n8n—scheduled, AI-generated, and published.
• For founders who maintain a specific tone and want Gemini to generate LinkedIn posts with a consistent structure and engagement plan.
