Snap the leaf
One tap opens the camera. Works with a 2 MP phone and no signal — the model runs entirely on device.
Built for the Thar · Works without internet
A pocket agri-scientist for every Rajasthan farmer.
Point your phone at a sick leaf. In seconds, KhetSarthi identifies the disease or pest on bajra, mustard, guar and cumin — and tells you what to do, out loud, in Marwari.

The flow
Four steps between a sick leaf and a saved harvest.
Hear the diagnosis
KhetSarthi speaks the result in Marwari or Hindi: what's wrong, how bad, and what stage of crop.
Get the treatment
Step-by-step spray schedule, dosage per bigha, and cultural practices — no jargon, just what to do this evening.
Reach a real human
One tap dials your nearest Krishi Vigyan Kendra or verified input dealer — with your photo already attached.
What's inside
Built for the constraints of a Marwar field.
Every feature was scoped with farmers in Barmer, Jaisalmer and Nagaur — not from a desk in Bengaluru. If it doesn't work on a ₹4,500 phone with 2G, it doesn't ship.
Offline-first vision model
A 12 MB quantized CNN runs on the phone itself. No data plan, no round-trip — usable in fields with zero bars.
Marwari & Hindi voice
Speak your question, hear the answer. Built for farmers who don't read fluently — every screen has an audio equivalent.
KVK & dealer routing
Diagnosis flows straight to the nearest Krishi Vigyan Kendra or verified input dealer, with the photo pre-attached.
Learns from your fields
Farmers confirm the outcome after treatment. Those labels re-train the model each season — accuracy grows with your village.
Weather-aware advice
Treatment plans adapt to next 48 hrs of forecast — no wasted spray before a dust storm or an unexpected shower.
SMS fallback
No smartphone? A shared village phone gets diagnoses back over SMS in Devanagari script. Nobody left behind.
Trained where you farm
Regionally relevant — not a generic “plant disease” app.
Our dataset started with 42,000 photos captured across 9 districts of Rajasthan. Every label was verified by a KVK agronomist. The model knows what a bajra ergot looks like at 42°C, in the actual light your field has.

The feedback loop
Every farmer who uses it makes it smarter for the next village.
Seven days after diagnosis, KhetSarthi asks one question in Marwari: “Did the treatment work?” Those answers become training data — reviewed by our KVK partners, then folded into the next model release.
