@useless asked if there was "any way to do this for default filters."

A round-about way to use default filters: pipe it through the standard filter before passing it to your custom filter and pass the original value as a parameter.

For example your Angular expression would look like this:

{{myDate | date: 'mediumDate' | relativeDate: myDate}}

And your filter:

var myApp = angular.module('myApp',[]);
myApp
    .filter('relativeDate', function() {
        return function(formattedDate, dateStr) {
            var returnVal = formattedDate,
                today = new Date(),
                evalDate = new Date(dateStr);
            if (today.getFullYear() == evalDate.getFullYear() &&
                today.getMonth() == evalDate.getMonth() &&
                today.getDate() == evalDate.getDate()) {
                    returnVal = 'Today'
            }
            return returnVal
        }
    })
    .controller('myAppCtrl', ['$scope', function myAppCntrl($scope) {
        $scope.myDate = "2001-01-01T01:01:01";
    });
