Features are the things your product does. The ways it can be used.
Benefits are the things your product can do for somebody. The results of using it.
This is a fine distinction but it’s a powerful one. Technical folks tend not to think about the difference. When you’re building the thing, you focus on the properties of the thing.
But when you’re selling the thing, you focus on the reasons someone would want the thing. Customers don’t care about the features of your product. They care about the benefits it can bring them.
