SarvFasal AI: A Smart Farming Assistant in Hindi and English for Farmers in the Field

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass

What I Built

SarvFasal AI is a smart farming website for Indian farmers. It puts the answers a farmer needs in one place: an AI assistant for crop questions, a leaf photo check for spotting plant problems, a Hindi/English language toggle, and a profit calculator that turns land area, yield, price and cost into income and profit or loss.

It is built for the farmer who is standing in the field, not sitting at a desk. Instead of keeping people on a screen, it helps them make quick decisions about water, fertilizer, pests and profit, so they can get back to the crops. The Hindi support means a farmer doesn't need English to use it.

🌾 SarvFasal AI

A smart farming website prototype that helps farmers ask questions, check crop health and calculate profit. Built with plain HTML, CSS and JavaScript.

Status: Early prototype. The AI assistant and leaf check currently give demo responses only. Real AI, live weather and mandi data are planned.

Features

AI Assistant: chat box that answers basic farming questions (water, fertilizer, pests, weather, mandi). Currently keyword-based demo answers.
Leaf Photo Check: upload a photo of a leaf and preview it. Disease detection is not connected yet.
Language Toggle: switch the whole site between English and Hindi.
Profit Calculator: enter land area, yield, price and cost to see income and profit or loss.

How I Built It

I'm a first-year CSE (AI/ML) student, and this is my first full project. The frontend is plain HTML, CSS and JavaScript with no frameworks, and it is hosted free on GitHub Pages.

AI assistant: the current prototype answers common farming questions (water, fertilizer, pests, weather, mandi) with keyword-based replies, in English and Hindi.
Leaf photo check: farmers can upload and preview a leaf photo in the browser.
Profit calculator: pure JavaScript, no server needed.

[TODO before submitting: name the open-source AI model you connect, e.g. an open-weight LLM for the assistant and an open image model for leaf disease detection, and explain how it runs (local inference, hosted open weights, etc.).]

Next on the roadmap: real open-source AI for farming Q&A and crop disease detection, then live weather and mandi price data.

Why Does Open Innovation Matter?

Farming tools often cost money, need fast internet, or only work in English. Open models and open code let a student like me build something for farmers in their own language without paying for a closed API. Anyone can read the code, improve the Hindi, add regional languages or retrain the model on local crops. Open innovation also means a farmers' group or agriculture college can run and adapt SarvFasal AI themselves instead of depending on one company.
