Ask HN: Mac app for quick capture notes?

Currently when I want to take a quick note, I normally cmd-tab to chrome, cmd-t to open a new tab, and just type my note as a google search and process it later.

But I'd prefer a standalone app now, so that I'm not putting all my notes into Google's search history.

What's a good mac app for quick note capture, with a global hotkey that I can use to quickly capture a one-line note at any time?
