Your data is never training data.
Every message, every photo, every voice note is processed on our own servers. We never train models on your inputs.
What you can do
Ask anything, on the go.
-
Chat with capable AI
Ask questions, write, brainstorm, translate. Powered by the best open-source models, running on our own measured, energy-optimised infrastructure.
-
Speak instead of type
Dictate long messages on the go and let GreenPT turn them into clean, structured text.
-
Snap a photo, get answers
Point your camera at a document, a menu, a receipt. GreenPT reads it and does what you ask.
-
See what every chat costs
An AI app that shows the energy and CO₂ of every conversation, right in the interface.
Why GreenPT is different
Nothing you type trains a model. Your AI footprint stays visible.
Energy and carbon measured on every request.
GreenPT measures energy from GPU hardware and carbon from live grid data. After every conversation, you see what it consumed. No offsets. Just the real number.
Built by a small team you can actually reach.
No ad model, no data brokering, no venture-scale pressure to squeeze users. Just people who thought the AI you use every day should be something you can trust with the things you care about.
