Passion.io and Kajabi cater to creators looking to build and monetize online courses, but they have differences in terms of features and pricing. Kajabi is an all-encompassing platform with a focus on course creation, marketing, and sales. Passion.io, however, specializes in mobile app-based course delivery. Creators should assess their specific needs, preferences, and budget constraints to determine whether Kajabi or Passion.io is the better fit for their online course business.
