Want to chat with an AI version of Hitesh Choudhary? Or maybe your favorite creator? In this project, I’ll show you how I built a working Hitesh AI Persona using OpenAI, Streamlit, and some thoughtful prompting.

📌 What You’ll Build

An interactive web-based chatbot that mimics the personality, tone, and storytelling style of a real person. In my case — Hitesh Choudhary. You can swap the prompt with any creator, founder, or yourself!

🧰 Tools You’ll Need

• 🧠 OpenAI API – To generate AI responses using GPT models.

• 🌐 Streamlit – For building an interactive web UI quickly.

• 🔐 python-dotenv – To securely load your API keys.

• 💻 Python (>=3.8) – The programming language to glue it all together.

🧱 Step-by-Step Build

1️⃣ Create Virtual Environment

python -m venv venv
source venv/bin/activate  # for Windows: venv\Scripts\activate

2️⃣ Install Dependencies

pip install streamlit openai python-dotenv

3️⃣ Add Your API Key

Create a .env file:

OPENAI_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxx

4️⃣ Prompt Engineering is the 💖

To simulate Hitesh Choudhary:

• Collected transcripts from 2-3 YouTube videos

• Studied his LinkedIn profile & Udemy courses

• Captured his tone: Hinglish, emotional, storytelling

• Created ~40 examples formatted like:

{
  "role": "user",
  "content": "Hitesh bhai, mujhe backend seekhna hai par kahan se start karu?"
},
{
  "role": "assistant",
  "content": "Bilkul, backend seekhna kaafi exciting journey hai. Dekho sabse pehle Node.js ya Python choose karo..."
}

These examples help anchor the AI's style and tone.

5️⃣ Main Streamlit App

Here’s a simplified version of persona.py:

import streamlit as st
from openai import OpenAI
from dotenv import load_dotenv
import os
import json

load_dotenv()
client = OpenAI()

SYSTEM_PROMPT = """
You are an AI version of Hitesh Choudhary.
You speak in Hinglish with storytelling flair, use simple analogies, emotional motivation, and break down tech concepts for learners. You are informal, encouraging, and sound like a relatable mentor.
"""

st.title("🤖 Chat with Hitesh Choudhary (AI)")
query = st.text_input("Aapka sawal?")

if query:
    with open("prompts/hitesh_examples.json", "r") as f:
        examples = json.load(f)

    messages = [{"role": "system", "content": SYSTEM_PROMPT}] + examples + [{"role": "user", "content": query}]

    res = client.chat.completions.create(
        model="gpt-4",
        messages=messages
    )
    st.write(res.choices[0].message.content)

📌 Tip: You can wrap this in a loop or append user history to make multi-turn conversations.

6️⃣ Run the App 🚀

streamlit run persona.py

It’ll open at http://localhost:8501 and boom 💥 — your own Hitesh AI clone.

🧠 Modify It For Yourself

Want to clone your own persona? Just change:

• The SYSTEM_PROMPT with your own style

• Feed 10–50 prompt-response pairs that match your tone

Example:

SYSTEM_PROMPT = "You are AI version of [Your Name]. You use Gen Z slang, emojis, and joke a lot."

🙌 Final Thoughts

You don’t need to train a full model or host LLMs to build a custom AI. Just tweak prompts creatively and let OpenAI + Streamlit do the rest.

If you build your own AI Persona, I'd love to see it! Share your version on X (Twitter) with the hashtag #AIPersona and tag me!

Whether it's your mentor, a favorite creator, or your own clone — the possibilities are endless.

Happy building! 🚀
