Easy UI for oneoff, isolated, no-history messages?

[amacinho]

A common use case for me is to paste a small code snippet to better understand the pattern used or ask for confirmation for an issue. I don't need to keep history and in the interest of saving on context, I launch a new chat every time I do this. Another way is to edit&resubmit button.

Is there an easier way to "chat" with the LLM, but without retaining any history / context? I would love to have a special chat window that exactly looks like the other chats, but no context is sent to the API when a new message is entered.
