I wanted a personal-finance tool for people who didn't want to be accountants: something you could set up in ten minutes and spend less than five minutes a week on. Mint is now that tool.
In the first three years of Mint, from when it was founded to when it was sold, I can honestly say that in a sustainable way, I couldn't have worked any harder on it.
Mint is designed to put your finances on auto-pilot. Whether you log in or not, it will send you a weekly summary of your balances and biggest purchases, and how your investments and budgets are doing, along with sending you alerts on unusual spending and low balances.
