What they are
Luma Dream Machine

It is used by content creators, social media managers, and motion designers who need quick video assets without traditional production. The output quality is impressive for short clips, but generation time and clip length constraints make it a tool for ideation and social content rather than long-form production.
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.
