What they are
Gamma
Gamma is an AI presentation and content platform that turns a prompt, outline, or pasted document into a presentation, webpage, or document using a fluid card-based format rather than fixed slides. It targets marketers, educators, consultants, and small business owners who need polished visual content without a designer. Outputs publish directly as web pages or export to PowerPoint, PDF, and Google Slides. The free tier is genuinely usable for testing, but its 400 non-refilling credits mean most regular users will need a paid plan.
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.
