Diminishing marginal utility means that each additional unit of something gives you less extra satisfaction. For example, your first slice of pizza when you’re hungry tastes wonderful. The second is good, but by the fifth you’re full. Each extra slice adds less enjoyment.

Can I pick up a previous conversation?
Yes. Each conversation keeps its context, so you can ask follow-up questions, add details, or try another angle. You can also switch to a saved conversation and pick up where you left off.
Where is my chat history stored?
Chat history is stored locally on your device. To answer your questions, relevant messages, images, and tool results may be sent to the model service in use. Web tools also access the corresponding websites.
Can I change the keyboard shortcut?
Yes. The default is Control + Option + Space — your hotkey to summon the AI agent. Change it in settings to avoid conflicts with other apps.
