Create AI LinkedIn posts with Groq, Tavily, Pollinations, Brevo and Telegram

Description

What This Workflow Does

This workflow automatically creates AI-powered LinkedIn posts on any topic — complete with a matching AI-generated image — and delivers everything via Email and Telegram. Every post is also logged to a Notion database for your records.

How It Works

User submits a topic via an n8n Form
Groq (LLaMA 3.3 70B) + Tavily researches the topic in real time
A second Groq agent writes a professional LinkedIn post
A third Groq agent generates an image prompt based on the post
Pollinations AI generates a free image from that prompt
Brevo HTTP API sends an email with the post text + image link
Telegram bot sends the AI image + post text directly to your phone
Notion automatically logs every post with timestamp
