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.

Udio

Udio is an AI music generation tool that produces complete songs, including vocals and instrumentation, from a text description. It is used by content creators, podcasters, indie game developers, and musicians looking for quick backing tracks or original compositions. The output quality is impressive for AI-generated audio, though the tool gives you limited fine-grained control over individual stems or arrangement details.
