GPTree: Sustainable AI Chat

GPTree is the mindful, honest way to talk to AI — an assistant that knows when less is enough. Everyday questions run on the lightest model that fits, honest numbers show what that saves, and your restraint grows into a forest you can watch take root. A QUIET PLACE TO THINK Ask anything. Answers arrive in a calm, beautifully typeset chat — no clutter, no feeds, no noise. Dictate with your voice, attach files, and keep bigger work organized in projects. Your chats sync across iPhone, iPad, and the web with Sign in with Apple or Google — and stay yours: never sold, never shared. THE LIGHTEST MODEL THAT FITS Most questions don’t need a frontier model. GPTree balances models behind the scenes, so everyday questions run on light, efficient ones. When you want more depth, Deep mode brings the strongest model — an explicit, labeled choice, never a silent upgrade. YOUR CHATS PLANT TREES As you chat, trees take root in your garden — a living botanical journal drawn as vintage naturalist plates. Twelve species across four rarity tiers, from the common Scots Pine to the legendary Dawn Redwood. Fill your Herbarium and keep a gentle streak — streak savers catch the days life gets in the way. HONEST NUMBERS, ALWAYS ≈ Choosing lighter models saves real energy. GPTree shows those savings as estimates — always prefixed ≈, always framed vs. a typical cloud AI chat, with the open methodology one tap away. Your garden grows in the app, not the ground: no offset claims, no planting promises, no greenwashing. DESIGNED LIKE A FIELD JOURNAL Cream paper, deep forest ink, watercolor botanical plates, and a dark mode of deep warm greens. GPTree is built to feel like a naturalist’s notebook, not another neon chat app. GPTREE PRO GPTree is free to try. GPTree Pro unlocks unlimited chats, Deep mode, and every species in the Herbarium.
