What they are
ConvertKit
ConvertKit is an email marketing platform aimed at bloggers, podcasters, course creators, and independent writers who need to grow and monetize a subscriber list. It combines email broadcasts, automated sequences, landing pages, and a paid newsletter feature in one place. The interface is simpler than enterprise tools like Mailchimp or ActiveCampaign, which makes onboarding fast but limits advanced design flexibility.
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.
