Google Squared 4

OK, it's hard to tell what this does from the description, so here goes:

Try typing in a list / category name like "Simpsons Characters" or US Presidents" or "San Francisco Bars."

Google Squared goes through the Google index, and generates a structured list of items that match your search query, including pictures and facts about each items.

In other words....

IT'S THE ULTIMATE WEBLIST BUILDING TOOL.
