What is Petri?
Petri turns real trees into digital collectibles (NFTs) that gain value as you take care of them.
Plant a tree in real life → Take photos to prove it's growing → Your tree NFT becomes more valuable and rare.
Think of it like Pokémon GO meets environmental action: collect rare tree species, care for them with help from our AI guide (Groot), and trade them as their health improves. The healthier your tree, the more valuable it becomes—verified by satellite data, not just trust.
🌟 Key Features
📍 Verifiable Tree Health System
- Capture your tree with GPS-pinned photos
- Real-time Tree Health Score (THS) calculated from satellite NDVI data
- Weekly photo uploads cross-checked against vegetation indices
- Transparent, tamper-proof growth tracking
🎨 Dynamic Living NFTs
- Each tree generates a unique NFT card with evolving metadata
- Rarity and value increase with tree health and species population
- Tradeable on public marketplaces with fractional ownership options
- Stewards retain 10% ownership stake permanently
🤖 AI-Powered Care Companion
- Groot: Your personal plant educator delivering species-specific 60-second lessons
- Custom chatbot for each tree (text and voice interaction)
- 1-tap care quests that turn alerts into action
- Smart recommendations based on weather and location data
📊 Forest Profile & Gamification
- Track your entire forest portfolio in one dashboard
- Level up as your forest grows and thrives
- Community mini-forests for collaborative stewardship
- Achievement system that rewards consistent care
Why Petri?
The Problem: People plant trees but rarely maintain them. Without ongoing care and motivation, survival rates plummet and environmental impact is lost.
Our Solution: Financial incentive + gamification + education = long-term tree stewardship. Just as NFTs sparked a digital art renaissance, Petri channels that same energy into environmental preservation.
How It Works
- Plant & Mint: Take a photo of your tree with exact GPS coordinates → Mint your TreeToken NFT
- Care & Verify: Upload weekly photos → System cross-checks with satellite NDVI data at your location
- Grow & Earn: Tree Health Score (THS) increases with real growth → Rarity and value update automatically
- Learn & Trade: Chat with Groot for care tips → Trade or fractionally share your TreeToken

The Vision
We're not just building an app—we're creating a movement. By combining the excitement of NFT collecting with tangible environmental impact, Petri makes tree stewardship financially rewarding, socially engaging, and verifiably transparent.
Every TreeToken is a living asset. Every care action matters. Every forest tells a story.
