LinkedIn Post Generator
Tools: n8n, Claude AI, Serper.dev, Gmail, Google Sheets
Overview
Overview
An AI-powered n8n workflow that automates LinkedIn content creation with full human oversight.
The workflow runs on a configurable schedule, picks up topics from a Google Sheet, researches each topic using live web search, and generates a post using Claude AI. The reviewer receives an email with a review form: approve or reject with feedback. If rejected, Claude rewrites the post incorporating the feedback and sends a new review request. Once approved, the post is delivered by email and the Google Sheet is updated.
Supports any language.
Who this is for: Professionals, consultants, and marketers who want to maintain a consistent LinkedIn presence without spending hours writing posts every week.
Note: LinkedIn has restricted API publishing for personal profiles. This workflow generates posts that are ready to copy and paste directly into LinkedIn.
How It Works
How It Works
1. The workflow runs every 30 minutes (configurable) and checks if the current time matches the posting schedule defined in Google Sheets
2. If it's time, the workflow picks the next pending topic from the Topics sheet
3. The topic is researched on the web via Serper.dev for current, factual grounding
4. Claude AI generates a LinkedIn post in the specified language
5. The reviewer receives an email with the generated post and a link to the review form
6. The reviewer can approve the post or reject it with written feedback
7. If rejected, Claude regenerates the post using the feedback, and a new review email is sent
8. Once approved, the final post is delivered by email (ready to copy-paste into LinkedIn) and the Google Sheet is updated with the post text and generation date
End-to-end workflow architecture: scheduled topic loading, AI generation, human review loop, and final delivery via email and Google Sheets
