NAB is launching a digital advice platform - to be known as NAB Prosper - to 40,000 of its internet banking customers, and along the way has claimed bragging rights as the first major bank to do so.  The bank has said that, "unlike robo advice, this will provide personalised, tailored advice on super and insurance." NAB's longer term plan is to expand into debt, cash flow, investments and estate planning in 2016.NAB Prosper will ask customers specific questions about their financial situation and future goals and provide them with "a tailored, personalised assessment - with the option to seek further advice if they feel it is necessary," the bank said.The underlying strategy is to reach the 80 per cent of Australians who do not have an active relationship with a financial adviser - although a bank spokesman said there was no expectation or push for customers to use NAB advisers.  NAB said the new service was still termed general advice, and was intenended to improve the cost-effectiveness of time spent with advisers, if clients arrived with a clear view of their risk appetite and goals already set out.
