Per-class custom instructions
Give a class standing instructions, like a citation style, a tone, or a rule to never write full essays, and they apply to every chat in that class.
Add instructions
Open the class, go to its Settings tab, and write your instructions. They're prepended to every conversation in that class, so you don't have to repeat yourself.
Tip. Good instructions are specific: "Use IEEE citations" or "Explain like I already know calculus" beats "be helpful."
