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.
Writesonic
Writesonic is an AI writing platform that generates blog posts, product descriptions, ads, and social copy using large language models. It targets marketers, agencies, and solo creators who need to produce a high volume of written content quickly. The platform includes a chatbot (Chatsonic), an AI article writer, and brand voice controls. Output quality is solid for drafts but still needs human editing before publication.
