What they are
Kling AI
Kling AI is a video generation platform from Kuaishou that turns text prompts or reference images into short video clips up to two minutes long. It targets content creators, marketers, and filmmakers who need generated footage without a production crew. The output quality rivals other top-tier generators, though render times on the free tier can be slow and credits are consumed quickly on longer clips.
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.
