NPK Sapien

NPK Sapien is an AI garden planner, mapper, and tracker that helps home gardeners and growers design and manage their growing space. You map your plants by importing a hand-drawn map or using simple drag and draw to place containers and plants, and NPK Sapien turns a hand-drawn plan into a digital replica with one click. As an AI garden planner it builds a digital twin of your growing space, including a sunlight simulation that shows which areas are shaded in the afternoon and how light changes by season, so you can plan placement around real light. It does not limit growing density or restrict you to a fixed plant library, so you can experiment freely. A co-grow assistant provides tailored answers rather than generic wiki-style advice: you set your city and North direction and it automatically factors in sunlight, season, macro and micro climate, and live weather. The assistant keeps a living biography of your plants, soil, and growing style so its guidance reflects your specific space. NPK Sapien runs as a free web app and is also available on Android, with the aim of more dig time and less screen time.

Home gardeners use NPK Sapien to map their growing space, simulate sunlight across seasons, and get climate-aware, personalized growing advice from a co-grow assistant.
