ConvertKit

Kit (formerly ConvertKit) is an email-first operating system designed for creators to build and monetize their audience. It provides tools for email marketing, audience segmentation, automation, and selling digital products and subscriptions. The platform aims to help creators foster deeper connections with their audience and build sustainable businesses.

ConvertKit, now rebranded as Kit, is primarily an email marketing platform for creators. While it offers tools for content creators to manage subscribers, send newsletters, and monetize their content, it does not provide a rich text editor for long-form articles or a comprehensive distribution and recommendation engine for content discovery in the same vein as Medium. Its focus is on email-first communication and sales rather than a public content publishing and reading platform. It does, however, offer features like membership monetization (paid newsletters/subscriptions), user profiles, tagging, and social sharing, which align with some 'other' features of Medium.
