If you mean a stylus, then all it would do would be to act like your fingertip. There's no active stylus support (like the S Pen on Galaxy Note devices) for Nexus devices (or most other devices, for that matter).
so it works but without active stylus support? dont really know what that is but it will work just like i am using my finger? does any stylus work on it? or do i gotta search for a special one?
Any stylus designed for a capacitative screen will work (so basically any stylus advertised to work with a smartphone). But don't expect it to do anything else besides what your fingertip can already do.
