At first glance, Quicksilver is a launcher for MAC OS. When opened, it will create a catalog of applications and some frequently used folders and documents. Activate it, and you can search for and open anything in its catalog instantly. The search is adaptive, so Quicksilver will recognize which items you are searching for based on previous experience. It also supports abbreviations, so you can type entire words, or just fragments of each. When not in use, Quicksilver vanishes, waiting for the next time you summon it.

Quicksilver’s greatest strength, however, is not search. Any item you are able to find, drag, or otherwise pull into its universe is endowed with many potential uses.
