What they are
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.
Jasper
Jasper is an AI writing tool aimed at marketing teams and content professionals who need to produce blog posts, ad copy, emails, and social content at scale. It runs on large language models and layers in brand voice controls so output stays consistent across writers. The platform is genuinely capable for structured marketing copy, though the monthly cost makes it harder to justify for solo creators with lighter output needs.
