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.

Leonardo AI

Leonardo AI is a browser-based image generation platform that produces high-quality visuals using a range of fine-tuned models, including its own proprietary ones. It is used by game developers, illustrators, and content creators who need consistent characters, concept art, or marketing assets at scale. The platform offers more model control than most consumer tools, though the credit system can feel restrictive on the free tier.
