A command bar that previews as you type

I'm building a tool that helps companies find, vet and book creators. I'm really digging this command bar I built in React.

Cmd+K opens it small: actions, recent briefs, places to go.

Type @ and it opens wide on creators, with their recent posts and the briefs they're in. Type # for tags: how many creators carry one, and who.

You can size someone up without leaving the bar.
