Rythu Mitra — రైతు మిత్ర

Vernacular-first AI business companion for Telugu-speaking farmers.

Chat-native farm management for India's 150M+ Telugu-speaking farmers. Voice to AI to Structured Records. Open source, offline-capable, designed with love.

"WhatsApp is for your life. This is for your livelihood."

What is Rythu Mitra?

Rythu Mitra (రైతు మిత్ర = "Farmer's Friend") is an AI-powered farm management app built specifically for Telugu-speaking farmers in Andhra Pradesh and Telangana. It understands Telugu voice input, tracks expenses and income, shows real-time mandi prices, and provides proactive farming intelligence — all on a Rs 10,000 phone over a 3G connection.

Built for Lakshmi

Our design persona is Lakshmi, 38, a groundnut and cotton farmer from Anantapur district. She manages 4 acres of dryland farming, pays laborers in cash, sells at the local mandi, and tracks everything in her head. Rythu Mitra gives her a digital memory that speaks her language.

Features

Telugu Voice Input — Say "కూలి 1000" and it records Rs 1,000 labor expense
AI Chat (Sarvam 105B) — Conversational interface in Telugu with live database context
Expense and Income Tracking — All money in integer paise, balance never stored (always computed)
Mandi Price Feed — Real-time market prices with MSP comparison across mandis
Crop Diary — Field events: planting, spraying, irrigation, pest observations, harvest
Bill OCR — Photograph dealer bills; AI extracts amounts automatically
Web Search — Agricultural knowledge with Telugu KB + DuckDuckGo + Sarvam fallback
Persistent Memory — AI remembers farmer preferences, patterns, and concerns
30-second Undo — Every financial action is reversible
Government Schemes — PM-KISAN, YSR Rythu Bharosa status tracking

Tech Stack

Layer	Technology
Frontend	Svelte 5, TypeScript, Vite
Database	SpacetimeDB (real-time sync, offline-capable)
AI	Sarvam AI (105B chat, STT, TTS, translation)
Design	Matti Design System (earth palette for farming context)
Intelligence	Ananta engine (digital root classifier, 4 validation gates, pattern detection)

Quick Start

Prerequisites

Node.js 18+
A Sarvam AI API key (free tier available)

Run the client

cd client
npm install
npm run dev

The app connects to the live SpacetimeDB instance on maincloud.spacetimedb.com. Enter your Sarvam API key in Settings to enable AI features.

Run the STDB module (optional — for local development)

cd module/spacetimedb
npm install
npm run build
npm run publish
npm run generate  # regenerate TypeScript bindings

Architecture Principles

Balance is NEVER stored — always computed from money_events (Phase 18 invariant)
All money is integer paise — no floating point, ever (Rs 1 = 100 paise)
Idempotency on financial writes — SHA256-based duplicate prevention
Telugu-first — 70+ keywords, fraction amounts (ఒకటిన్నర = 1.5), verb conjugations
Offline-capable — local fallback data, localStorage persistence, sync when online
AI with guardrails — 4 validation gates (sanity, consistency, duplicate, quality)

Testing

cd client
npm run build        # Production build (zero errors)
npx vitest run       # 358 tests, all passing
npx svelte-check     # Type check (0 errors, 0 warnings)

Contributing

Contributions welcome! This project serves real farmers — please be thoughtful about:

Telugu accuracy — verify keywords with native speakers
Offline behavior — test without network connectivity
Low-end devices — target Rs 10,000 Android phones (2GB RAM, 3G)
Financial correctness — money operations must be exact (integer paise)
