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.
Windsurf
Windsurf is an AI-native IDE centered on Cascade, an agentic coding interface that reads your entire codebase and makes coordinated edits across multiple files from a single prompt. It ships proprietary models (SWE-1, SWE-1.5) alongside access to Claude, GPT, and Gemini, plus browser previews, deploys, and Devin cloud sessions for background development. Individual developers and teams use it as a full Cursor alternative. Note that the product is transitioning to the Devin Desktop name under Cognition, which may affect branding consistency going forward.
