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.
Flux
Flux is a family of text-to-image models from Black Forest Labs, the team behind Stable Diffusion. It generates high-resolution, photorealistic and stylized images from text prompts, with strong prompt adherence and fine detail. Creators, designers, and developers use it via API or third-party platforms. Flux produces genuinely impressive output, but there is no native consumer app, so getting started requires some technical setup or a compatible host.
