A mindful AI chat for iOS
AI that doesn't cost the earth
Light models for everyday questions, honest numbers, and a garden that grows as you chat — every 5 messages plants a tree.
Difference one
The right model, every time
GPTree balances models behind the scenes — everyday questions go to light, efficient models instead of always burning the biggest one. Each answer uses ≈ a fraction of the energy of a typical AI chat.
Difference two
Honest numbers, always
Every figure you'll see is an estimate, marked with ≈ and compared to a typical cloud AI chat. The methodology is open — if we can't defend a number, we don't show it.
Your impact

Estimates. Methodology open in the app
Difference three
Restraint you can see
Every 5 messages plants a tree in your forest. It grows slowly, over months — a quiet record of choosing the greener way to chat.
The Herbarium
12 species. Four rarities. One quiet collection
Every planting rolls a species — common to legendary. First discoveries press a new stamp into your herbarium, and completing a rarity tier earns a cover embellishment.
Odds at planting: common 70% · uncommon 22% · rare 7% · legendary 1%
Every number in GPTree is an estimate, marked ≈ and compared to a typical cloud AI chat. The methodology is open — if we can't defend a number, we don't show it. No offset promises, no real-world planting claims, no greenwashing.
A quiet place to think
Ask anything. Plant something. GPTree is coming to the App Store for iPhone and iPad.
