GreenHub is a fully Bangla-language, AI-powered platform built for Bangladeshi farmers and plant lovers, making plant and crop disease diagnosis simple, fast, and completely free. Users simply take one or more photos (up to 4) of an affected leaf, stem, flower, or bud, and our AI accurately identifies fungal, bacterial, viral, pest, or nutrient-deficiency issues within just 30 seconds. Every diagnosis comes with a severity indicator, an eco-friendly organic/natural treatment recommendation, and — when needed — the exact chemical name, dosage, and application method, along with guidance on its environmental impact. No account or registration is required to use the platform, and user photos are never stored — data is automatically deleted immediately after analysis, ensuring complete privacy. From rice paddies, vegetables, and fruit trees to potted plants at home, GreenHub can identify problems across virtually any type of plant, reducing the need to visit agricultural offices in person and helping farmers make timely, informed decisions. With its fully Bangla interface and results, GreenHub has become an accessible tool for everyone — from smallholder farmers in rural Bangladesh to urban gardening enthusiasts in the city.
