You can send custom AI instructions with every request

Small power-user feature in Fud AI that I love as a builder: optional custom AI instructions.

You write a bit of text and it gets sent along with each request. So you can tell the AI things like how you usually portion meals, or to assume metric, or to be blunt with you. It steers the estimates and the Coach without me hardcoding anyone's preferences.

Combined with BYOK and model choice, you basically tune your own assistant.
