About

Terravis by Argentis

Features
Read full description

Terravis is a farm-aware assistant for smallholder farmers across Ghana, Jamaica, and beyond. Take a photo of a leaf, get a disease diagnosis. Open the app each morning, get a briefing on what your day looks like. — DISEASE DETECTION — Point your phone at any crop leaf and Terravis identifies the disease (or confirms healthy) in seconds. The system uses a tiered approach: • Cocoa: a custom EfficientNet model trained on tens of thousands of cocoa disease photos, deployed on dedicated GPU infrastructure. • Jamaica pilot crops (sweet pepper, tomato, onion, cucumber, breadfruit, ackee, apple): a multi-class CNN trained on PlantVillage + iNaturalist images, with 90%+ validation accuracy on every crop. • Other crops: routed through Claude AI with reputable agricultural sources (FAO, CABI, USDA, university extension). Low-confidence scans automatically queue for review by an agronomist. You'll get a notification when your scan has been confirmed or updated. — DAILY MORNING BRIEFING — Each morning before you head to the field, Terravis sends a 60-second briefing covering today's weather, any disease alerts in your region, market price moves on your crop, and one suggested action. — LIVE MARKET PRICES — Local market prices, crowdsourced from farmers in your region. See the 7-day median for your crop, contribute your own sale prices, and watch the network grow stronger over time. Outlier prices are auto-flagged so the median stays honest. — TALK TO YOUR FARM — Ask the chatbot anything — fertilizer timing, pest identification, irrigation strategy. Powered by Claude AI with your farm's context (size, region, crop, recent scans) so the answers are specific to your operation. — OFFLINE-FIRST — Designed for spotty connectivity. Scans queue locally and sync when you have signal. Critical data is cached for offline reading. — BUILT WITH FARMERS — We're piloting with cocoa farmers in Ghana and a 40-60 farmer pilot cohort in St. Elizabeth, Jamaica. Every feature is shaped by direct farmer feedback. — PRIVACY — You can delete your farm and all associated data from inside the app at any time — Settings → Account → Delete Farm. Privacy policy: argentis-fsri-api-production.up.railway.app/legal/terravis/privacy — DISCLAIMERS — Terravis provides agricultural guidance, not pesticide / chemical recommendations. For severe symptoms or chemical-related health concerns, contact a local agronomist or extension officer. Yield and price forecasts are model-based — use them as one input alongside your own knowledge. Need help? support@argentis.company
