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.
Swell AI
Swell AI ingests podcast episodes, YouTube videos, or audio files and generates transcripts, show notes, blog posts, social clips, and newsletters from a single upload. It targets podcasters and video creators who want to repurpose content without hiring a writer. The output quality is solid for first drafts but typically needs editing before publishing. A free tier exists with limited monthly credits.
