Talk to ForestsUnderstandthe Trees

A living map of trees, grounded in real-world data, tree growth simulations and impact estimates. Assisted by AI, where every tree has a voice.

Meet gAIa

Built for city planners, arborists, schools, agroforesters and tree enthusiasts.

gAIa voices our collective intelligence on trees
Our knowledge of trees is vast—but scattered. Some data sits behind expensive licences. Some is outdated. And for many trees, it simply doesn't exist. This is especially true on private land, which can make up a large share of a city's canopy. For urban greening teams, that creates a blind spot. And when local experts move on, much of their practical knowledge goes with them.
Trees are as essential as roads or bridges. They clean the air, cool our streets, reduce flood risk, and make neighbourhoods healthier and more liveable. They are also living landmarks—hosts to biodiversity and holders of collective memory. Yet because these benefits are hard to see and measure, trees too often appear only as costs.
gAIa is an AI companion for trees, built for everyone—from school children to senior arborists. It helps people learn, contribute observations, and take care actions in both public and private spaces. It also brings together data, local knowledge, and simulations, so users can explore how trees might grow and what benefits they may provide over time.

What gAIa Offers

Learn care. Feel connection. See impact.

Visibility

Impact you can see

Every tree provides essential services: capturing carbon, cooling the city, improving air quality, supporting biodiversity, and reducing water runoff. gAIa makes these impacts visible and explorable through simple questions and clear charts, so anyone can understand nature's real value. Through our modelling platform Green Urban Scenarios (GUS), gAIa shows impact estimates for all trees in a selected area—or an entire city—under different climate and maintenance scenarios.
Good for urban planners, greening initiatives, and municipal officers.

Intelligence

Care with guidance

gAIa turns complex datasets into practical insights and tree-care actions. It highlights which trees need attention and guides species identification, helping users expand their knowledge along the way. Anyone can add a tree to the map and explore how it may grow over time, once planted.
Good for arborists, municipal teams, and citizens who want practical, timely tree-care guidance.

Community

Nature with context

gAIa supports an active connection with nature. In gAIa, trees can have humour, personality, and memory. They can hold stories shared by the community and bring them up in conversation. And sometimes, they ask for help. Through playful prompts—measuring, photographing, or recording observations—each tree becomes more unique and the system becomes smarter. Every contribution, no matter how small, strengthens gAIa as a collective living map and gives citizens a meaningful role in shaping the future of their environment.
Good for citizen science campaigns, participatory education in schools, and preserving the natural heritage of monumental trees and parks.
