What they are
Kajabi
Kajabi is an integrated platform where creators build and sell online courses, memberships, coaching programs, and digital downloads without stitching together separate tools. It combines a website builder, email marketing, payment processing, and community features under one subscription. Coaches, course creators, and consultants make up the core user base. The convenience comes at a premium price that may be hard to justify for creators just starting out.
Substack
Substack is a publishing platform where writers host email newsletters and charge subscribers a recurring fee. Independent journalists, essayists, and niche experts use it to build direct audiences without relying on ad revenue. The platform handles payments, delivery, and a basic website automatically. Substack takes a 10% cut of paid subscription revenue on top of stripe fees, which becomes a real cost as an audience grows.
