Add-on [you] Tag

Is there a [you] tag addon, where when a user types

[you] it replaces it with the name of the user viewing that text?


[you] is awesome! would become TruthElixirX is awesome! when I viewed it, but would show up with your username when you viewed it.

I tried looking for it, but it is a bit hard to find a good result when searching for [you].
