Hi, Tree turns the trees you walk past into named places. Spot a tree. Take a photo. Give it a personal name and pin it on a community map of monumental trees. The first person to claim each tree becomes its naturalist — and once it's yours, it's yours. A small, slow collection. Hi, Tree is a naturalist's notebook for the world's trees. Build a personal collection one walk at a time. Open the map and discover the trees other people have already loved — the oak in front of someone's grandmother's house, the cedar on the edge of a park, the tree at the bottom of your street that someone gave a name to before you walked past it. Find a tree no one's named yet. Other trees on the map are still unclaimed — monumental ones that have been mapped but never named, waiting for the first naturalist to show up. The plane tree by your bus stop. The oak in the park down the road. The cedar that's been there longer than your neighbourhood. Open the map, pick one near you, walk over, take its photo, and give it a name. Some have been waiting months for someone to notice them. Tree Chat — your AI naturalist companion. Tap any tree and ask. Hi, Tree uses AI to identify the species from your photo and surface the things a curious naturalist would want to know — likely age, regional history, seasonal behaviour, what to look for next time. AI suggestions are best-effort, not gospel; check anything you'd act on. A living record, written by everyone. Trees in Hi, Tree aren't frozen the moment they're claimed. Add photo updates as the tree changes through the seasons. Leave a comment on a tree someone else claimed, and the owner can reply. Tap a heart to like a tree you love — its naturalist gets a quiet push notification. Check in at the trees you visit on your walks, and see the top naturalists on a community leaderboard. The trees you love become part of a shared, living record — one anyone on earth can walk up to and listen to. Carry your collection with you. Sign in with Apple or Google to keep your trees, claims, check-ins, and likes on every device you use. Or skip it and stay anonymous — the choice is yours, and you can decide later. What you can do with Hi, Tree • Photograph and claim a tree on your walk • Name it, write a field note, and pin it on the map • Build a personal collection of trees that mean something to you • Hunt down unclaimed monumental trees on the map and be the first to name one • Discover trees other naturalists have already claimed near you • Check in at trees you visit and rise up the naturalists' leaderboard • Comment on others' trees and reply to comments on yours • Add fresh photos of any tree as the seasons change • Like trees you love and get push notifications when yours are liked • Ask Tree Chat about species, age, and seasonal changes • Share a beautifully composed specimen card with friends • Sign in with Apple or Google to sync across devices For people who notice trees. Hi, Tree doesn't pretend to do conservation work directly. It's a tool for paying attention. We think attention is upstream of caring, and caring is upstream of action. Free. iPhone-only for now. — About claiming: claiming a tree on Hi, Tree is a personal and community gesture, not a legal one. Nobody owns a tree. Think of it the way you'd think of naming a star — a small ritual of attention. Privacy: we don't sell your data and don't run advertising. Full policy at hitree.app/privacy-policy.
