What they are
Bolt.new
Bolt.new is a browser-based AI app builder by StackBlitz that generates, runs, and deploys full-stack web applications from a plain-text prompt, with no local setup required. It uses WebContainers to execute code live in the browser, supports multiple JavaScript frameworks, and integrates with Supabase, GitHub, Figma, Netlify, and Stripe. Pricing runs on a token consumption model, where larger and more complex projects burn through allocations faster than simple prototypes. The free tier is genuinely usable for experiments, but the daily token cap makes it impractical for sustained development work.
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.
