The invention relates to a computer-implemented method for virtually assisting a user with a digital assistant comprising at least one iteration of a step, called an assisting step, comprising receiving a user input, predicting at least one potential action corresponding to the user input, and confirming one of the at least one potential action as a correct action corresponding to the user input. The method includes a prefetching step, the prefetching step including triggering execution of the at least one potential action before the confirmation step, such that, if the at least one potential action corresponds to the correct action, a response time to the user input is shortened.
