Why Streamlit for the first app

You could spend a week setting up Next.js, Tailwind, and Vercel for your first chat app. Or you could spend 4 hours with Streamlit and have something live tonight. The choice is obvious for beginners.

Streamlit is the IKEA furniture of AI UIs. Not luxurious, but you assemble it in an afternoon and it works.

Streamlit is a Python library that turns scripts into web apps. It auto-handles UI components, reactivity, and hosting. Perfect for AI demos, data apps, and your first chatbot.

For a real production product you would graduate to Next.js or FastAPI + React. For learning and portfolio, Streamlit is unbeatable.

Streamlit hello world:

import streamlit as st
st.title("My first AI app")
name = st.text_input("Your name?")
if name:
    st.write(f"Hello, {name}!")

Run with: streamlit run app.py. A browser tab opens. That is the entire workflow.
