The short answer

PandasAI (23,688 stars) is a Python library that answers questions about your data in plain English - it translates "what is the average order value by country" into the right pandas code and runs it. Streamlit (45,474 stars, Apache-2.0) turns any Python script into a shareable web app. Together they replace expensive BI tools for most small-team analytics.

10-minute setup

pip install pandasai streamlit

import pandas as pd
from pandasai import SmartDataframe

df = SmartDataframe(pd.read_csv("sales.csv"))
df.chat("Which country has the highest average order value?")

Building the dashboard

import streamlit as st
st.title("Sales Q&A")
uploaded = st.file_uploader("Upload CSV")
if uploaded:
    df = SmartDataframe(pd.read_csv(uploaded))
    q = st.text_input("Ask your data:")
    if q:
        st.write(df.chat(q))

Run with streamlit run app.py - you get a shareable URL instantly.
