FieldWise is an offline first crop-protection assistant for smallholder farmers and the extension workers who support them. When finding damage in Maize or Cassava leaves, the nearest extension officer may be days away and the mobile signal on the farm is inconsistent. A cloud-only AI assistant needs a connection for every question, sends the farmer's words and photos off the phone, and a general-purpose model can state some facts with no sources. This solution puts the answer in the village. One shared machine at a co-op or extension office acts as a hub and lets any phone use the browser over the hub's Wi-Fi, with no mobile data. Glimmer answers from FAO extension guides, cites the page and shows its confidence level. Only low-confidence cases go to Spark in the cloud, after the hub removes personal details. With no signal, it waits in a queue and the farmer gets the hub's answer marked as tentative. SAM 3.1 outlines the leaf in a photo so that off-colour tissue can be marked. Every answer passes a safety check; chemical-related questions carry a protective label and a follow-the-label reminder, and anything the guides don't cover is referred to the local extension officer.
