How to install Nut AI for free

Before you start: A Mac (for iPhone) or any computer with the Android SDK, and a USB cable. Photo scans run on publik API with no key to paste — linking your publik account gives $0.05 of free use once, then the app pays publik's published price per scan, and your own key still works.

Point your camera at a meal — honest calorie ranges, no key to paste. Pick the setup you have and follow the steps. Every command is written out — you do not need to know what any of it means.

We would rather tell you now than halfway through.

Would you rather not do this by hand?

Iris is our free desktop app. Hand it the install and it runs the commands for you in its own terminal, fixes what it can when something fails, and stops to ask before anything it should not do on its own.
