It provides a modern-ish code completion interface. Take a look at the 
home page. It has a description and a couple of screenshots.

It calls clang to know the possible completions at point, and their 
signatures (it passes the buffer contents through stdin, and the line 
and column of point). No persistent process, so I'd imagine it's not 
very suitable for large projects.

You might want to give company-clang.el a read. It's short enough.

They provide completions using different other sources, in different 
major modes.
