Human-in-the-Loop LinkedIn Post Generator (Telegram + AI)

This n8n template demonstrates how to build a human-in-the-loop AI workflow that helps you create professional LinkedIn posts via Telegram. The agent searches the web, drafts content, asks for your approval, and refines it based on your feedback — ensuring every post sounds polished and on-brand.

Who’s it for

• Content creators and marketers who want to save time drafting LinkedIn posts.
• SaaS founders or solopreneurs who regularly share updates or insights.
• Anyone who wants an AI writing assistant with human control in the loop.

How it works / What it does

1. Trigger: The workflow starts when you send a message to the Telegram bot asking it to write a LinkedIn post (e.g., “Write a LinkedIn post about AI in marketing”).
2. Research: The AI agent uses the Tavily tool to search the web and gather context for your topic.
3. Drafting: An AI model (OpenAI or Gemini) creates a professional LinkedIn post based on the findings.
4. Human-in-the-loop:
   • The bot sends the draft to you in Telegram and asks: “Good to go?”
   • If you approve → The post is saved to a Google Sheet, ready to publish.
   • If you disapprove and give feedback → The feedback is sent to a second AI agent that revises and improves the post.
   • The improved draft is sent back to you again for final approval.
5. Finalization: Once approved, the post is appended to a Google Sheet — your ready-to-post content library.

This workflow combines AI creativity with human oversight to produce polished, authentic LinkedIn content every time.

How to set up

1. Import this template into your n8n account.
2. Connect your Telegram bot (via Telegram Trigger and Send Message nodes).
3. Connect your Google Sheets account to store approved posts.
4. Set up your AI model provider (OpenAI or Gemini) and Tavily API key for web search.
5. Activate the workflow and start chatting with your AI writing assistant on Telegram!

Requirements

• n8n account.
• Telegram bot token.
• OpenAI or Google Gemini account (for text generation).
• Tavily API key (for web search).
• Google Sheets account (for saving approved posts).

How to customize the workflow

• Post Tone: Adjust AI prompts to match your personal voice (professional, storytelling, inspirational, etc.).
• Approval Logic: Modify the approval step to allow multiple revision loops or add a “draft-only” mode.
• Storage Options: Instead of Google Sheets, save approved posts to Notion, Airtable, or your CMS.
• Multi-platform: Extend the same logic for X (Twitter) or Threads by changing the final output destination.
• Branding: Add your brand guidelines or preferred hashtags to the AI prompts for consistent style.

This template helps you write better LinkedIn posts faster — keeping you in full control while AI does the heavy lifting.
