Interesting is one of those familiar adjectives that we reach for so often, it verges on filler. Compelling is a more intense form of interesting that can bring your meaning into focus. When something is compelling, in the sense of having a powerful and irresistible effect, it commands our attention. The adjective comes from the verb compel, which means "to force or drive, especially to a course of action." Compelling cases or compelling arguments force us to consider them. Art can be visually compelling, drawing us in and capturing our attention. Similarly, good books are often described as compelling if we cannot put them down.
