The PlantGPT prototype is currently undergoing testing on houseplants as the team works on refining its capabilities.
At Spelman College’s Arthur M. Blank Innovation Lab, Joy Rutledge and Temple Dees are developing an AI program that transforms environmental data from plants into real-time care guidance.
The initiative, known as PlantGPT, integrates plant sensors with artificial intelligence software, analyzing environmental conditions to offer insights into plant health. A dedicated team of Spelman innovators—Rutledge, Dees, Grace Burch, Jessica Obi, and Devyn Washington—contributes to the project throughout its various stages.
“Plant GPT is a means of communicating with your plants,” Rutledge shared in an Instagram video created by Spelman. “When your plant is struggling, it’s essential to know what it needs—whether it’s water, sunlight, or nutrients.”
The system collects readings from its environmental sensors placed near the plant, monitoring factors like soil moisture, humidity, temperature, and light exposure. The gathered data is then sent to an artificial intelligence model that analyzes the information and generates care recommendations.
“We’ve essentially built sensors linked to AI,” Dees stated. “This allows you to receive real-time data from your plant, enabling you to adjust its conditions promptly.”
The concept for this project originated with Grace Burch, a Spelman College biology graduate who began developing the prototype as part of her research within the Innovation Lab.
The initial version of PlantGPT utilized Arduino hardware, with subsequent updates introducing various technical improvements.
“My contribution involved switching the AI model to Tiny Llama, which operates locally without the need for internet access. I also added new features, including written responses, and we’re currently working on a vocal response option,” Dees elaborated.
The prototype is presently being tested on houseplants while the team continues to refine the system’s functionalities.
The project has also garnered attention through entrepreneurship initiatives linked to the college. PlantGPT was awarded $1,000 at the Center for Black Entrepreneurship’s New Venture Competition in 2025, funds which have aided in further development. Additionally, PlantGPT earned top accolades at the AAAS Making & Innovation Competition in Washington, D.C.
