What's the difference between "right" and "you know"?

"Right" and "you know" are often used as gap fillers when speaking, but "right" also has additional usages. It can be used to seek agreement, approval, or confirmation. In this case, the speaker has actually used "right" here to seek agreement or confirm something with the audience (the grammar rule). Ex: It's going to rain today, right? Ex: You already called the taxi, right?
