AI that knows when less is enough
Everyday questions go to a light model, hard ones to a strong one. Same answers, a fraction of the energy — and every five messages plants a tree.

The routing
The right model, without picking one
Standard handles the everyday — rewriting a sentence, dinner ideas, one confusing error message. Deep wakes the strongest model for long documents and the genuinely hard problems.
You never choose. You just ask, and GPTree starts light and steps up only when the task earns it.
The receipt
Same answer. A fraction of the energy
A GPTree answer costs roughly 0.1 Wh against about 3 Wh for a frontier model — a saving of ≈ 2.9 Wh, every time.
Messages × 2.9 Wh is the energy saved; × 0.4 g is the CO₂ avoided. Two multiplications, no black box, and the whole method is readable inside the app.
Your impact

Estimates, always marked ≈ and compared with a frontier model. Methodology open in the app.
The everyday kit
A lighter default, not a smaller app
Choosing the greener path shouldn’t cost you anything you actually use.
Projects
Group related chats into a project, and give that project its own memory so you stop re-explaining the context.
Memory
GPTree keeps the details worth keeping — across every chat, or scoped to one project. You can read them and forget any of them.
Web search
When a question needs today's answer, GPTree looks it up and shows you the sources it used. No toggle to remember.
Reads a link
Paste a URL and it reads the page before answering, rather than guessing from the address.
Attachments
Up to five files a message — PDFs, spreadsheets, code, plain text and images, from Files, Photos or the camera.
Voice
Dictate instead of typing. Where your language supports it, your speech becomes text on your device and never leaves it.
Change one
Your lighter chats grow a garden
Every five messages plant a tree. Streaks bring critters. It grows slowly, over months — a quiet record of choosing well.
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.
