How I Built an AI-Powered LinkedIn Post Generator App: Step By Step | 2025

Introduction: The Genesis of an AI-Powered Content Creation Tool

In the rapidly evolving digital landscape, content creation has become both an art and a science. As a freelance web scraper, data analyst, and AI enthusiast, I embarked on a journey to simplify LinkedIn content generation by developing an innovative AI-powered post generator.

The Problem: Content Creation Complexity

Creating engaging LinkedIn posts is challenging. Professionals struggle to:

  • Maintain consistent content quality
  • Generate posts across various topics
  • Adapt to different language styles
  • Produce content efficiently

Technical Architecture: Breaking Down the Solution

Core Technologies

My LinkedIn Post Generator leverages cutting-edge technologies:

Architectural Components

Full Source code:

Here I am just showing the skeleton of the codes and explaining. The full source is in my github

1. Data Collection and Preprocessing

def process_posts(raw_file_path, processed_file_path):
    # Collect posts
    # Extract AI-powered metadata
    # Unify tags
  • Scrape raw LinkedIn posts
  • Extract metadata (line count, language, tags)
  • Unify and standardize tags using AI

2. Few-Shot Learning Approach

The FewShotPosts class implements a sophisticated learning mechanism:

class FewShotPosts:
    def get_filtered_posts(self, length, language, tag):
        # Filter posts based on specific criteria
        return filtered_posts

3. Post Generation Engine

The core generation logic:

def generate_post(length, language, tag):
    # Retrieve contextual examples
    # Generate AI-powered post
    return generated_post

4. Calling LLM

from langchain_groq import ChatGroq
import os
from dotenv import load_dotenv

load_dotenv()
llm = ChatGroq(groq_api_key=os.getenv(“GROQ_API_KEY”), model_name=”llama-3.1-70b-versatile”)


if __name__ == “__main__”:
    response = llm.invoke(“Two most important ingradient in tea are “)
    print(response.content)

5. Customtkinter GUI

class App(ctk.CTk):
    def __init__(self):
        super().__init__()
     
        # Configure appearance
        ctk.set_appearance_mode(“dark”)
        ctk.set_default_color_theme(“green”)
#———————————

app = App()
app.mainloop()
