A robo-advisor is like a robot that helps you manage your money. Just like real people advisors, robo-advisors will give you advice about which investments to choose, to help you get more money. The difference is that robo-advisors are computers, not people. They can follow instructions quickly and make decisions based on exact equations, rather than just their own opinions. A robo-advisor can save you a lot of time and help you make better decisions when it comes to investing your money.
