30 Days Of AI with Streamlit 🎈

Welcome to #30DaysOfAI — a comprehensive 30-day challenge to learn, build, and deploy AI-powered applications using Streamlit and Snowflake Cortex AI.

🎯 What You'll Build

Master AI app development from chatbots to production-ready RAG systems and intelligent agents.

📏 Challenge Rules

1. Access the daily challenge

   • 💻 Code: github.com/streamlit/30daysofai
   • 🕹️ Instructions: 30daysofai.streamlit.app

2. Build the app following daily instructions

3. Share your progress on social media with #30DaysOfAI

4. Complete all 30 days and DM Chanin Nantasenamat or Jessica Smith

5. Get recognized in the Hall of Fame 🏆 (+ possible swags and stickers!)

🚀 Getting Started

Prerequisites

• Python 3.11, 3.12 (3.13 will work if llvmlite, numba are installed)
• Snowflake free trial (120 days of credits)
• Basic Python knowledge
• Enthusiasm for AI! 🧠

Locally

1. Install dependencies

   pip install -r requirements.txt
   # or with uv:
   uv pip install -e .

   requirements.txt:

   streamlit==1.52.0
   snowflake-ml-python==1.20.0
   snowflake-snowpark-python==1.44.0
   

2. Configure Snowflake secrets

   Create .streamlit/secrets.toml in your project root:

   [connections.snowflake]
   account = "your_account_identifier"
   user = "your_username"
   password = "your_password"
   role = "ACCOUNTADMIN"
   warehouse = "COMPUTE_WH"
   database = "your_database"
   schema = "your_schema"

   Important: Add .streamlit/secrets.toml to .gitignore — never commit secrets!

3. Run the app

   cd app
   streamlit run day1.py

In Snowflake

Recommended for production — no secrets setup needed!

1. Navigate to Snowsight → Streamlit
2. Create new Streamlit app
3. Copy code from app/dayX.py
4. Run in Snowflake

Benefits:

• ✅ Automatic authentication
• ✅ Production-ready by default
• ✅ Inherits Snowflake security
