What they are

Leonardo AI

Leonardo AI is a browser-based image generation platform that produces high-quality visuals using a range of fine-tuned models, including its own proprietary ones. It is used by game developers, illustrators, and content creators who need consistent characters, concept art, or marketing assets at scale. The platform offers more model control than most consumer tools, though the credit system can feel restrictive on the free tier.

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.
