MomCart: Google Gemma4 Challenge

A Telegram bot that lets mom build a grocery list by voice, photo, or text — and ships a live packing checklist to the neighborhood shopkeeper with one-tap status buttons.

What I Built

MomCart: A Telegram bot that turns the daily grocery struggle in Indian households into a 30-second conversation.

The problem is everywhere: my mom spends 2-3 days hand-writing the monthly pantry list on paper, photographs it, and sends it to our neighborhood shopkeeper on WhatsApp. She forgets items, sends correction messages, and the back-and-forth eats 30+ minutes for both of them. Multiply this by every mother and every small kirana shopkeeper in India and you're looking at millions of hours of friction every month friction that exists because the tools built for grocery shopping (BigBasket, Blinkit) ignore them entirely.

MomCart fits the workflow they already use. Mom speaks a Hinglish voice note - "do kilo aata, ek paav haldi" and the bot adds items to a persistent cart that lives across days. She edits with natural language ("no, make it 3 kg potato"), checks the cart anytime with /cart, and only when she says "bhej do" does the order ship to the shopkeeper as a structured Telegram message with ✅ ⚠️ ❌ buttons next to each item.

When the shopkeeper marks something out of stock, the bot proposes substitutes from the same category and remembers the unmet need in a wishlist so the next shopping cycle, MomCart proactively reminds mom about the items she wanted but didn't get. It's not a chatbot. It's a closed-loop agent with memory across weeks.

For mothers who aren't tech-savvy: voice, photo, or text all on Telegram, no app to install. The bot replies in whatever language mix she used (English, Hindi, or Hinglish), automatically.

For small shopkeepers: clean structured orders instead of WhatsApp screenshots, one-tap status updates, and zero workflow change beyond installing Telegram.
