Is there a plugin that can autofill(ajax) during user input?

I haven't done rails in a year, but can someone tell me if there is a
plugin or how much work is it to add an auto fill function like google's
front page?

Would you just use an observer on the form or is there already a built
in class that can do this?

Thanks!
