1. A computer-implemented method for dynamically customizing a graphical interface, the method comprising: storing, at a computing device, multiple functions for a graphical interface, wherein the stored functions are executable on a remote device, wherein the graphical interface is associated with the remote device, and wherein the graphical interface facilitates communication between the remote device and a third party device; transmitting an initial set of data, wherein the initial set of data is associated with an initial function of the multiple functions, wherein when received at the remote device, the initial set of data causes the remote device to display the graphical interface, wherein the graphical interface includes the initial function, and wherein the initial function facilitates a communication session between the remote device and the third party device; receiving input corresponding to an interaction with the graphical interface, wherein the input is received during the communication session; analyzing the received input, wherein analyzing includes detecting whether the received input satisfies a condition, wherein analyzing includes applying a rule to the received input when the condition is satisfied, and wherein applying includes identifying additional information associated with the received input; selecting an additional set of data, wherein selecting includes using the received input and the additional information, and wherein the additional set of data is associated with an additional function of the multiple functions; and transmitting the additional set of data, wherein when received at the remote device, the additional set of data causes the additional function to be included in the graphical interface, such that the additional function is available for use with the graphical interface for the communication session.
