Cartanza

Cartanza is a strong match for the Medium concept. It explicitly states it's built on Ghost, which is known for its rich text editor and blogging capabilities. The platform offers membership options for content monetization, as seen in the pricing page and the 'Subscribe to Cartanza' section in the demo. While not explicitly detailed, Ghost's core functionality includes community feedback tools (comments), user profiles, tags/topics, and social sharing. The 'Manage' section implies analytics, and the demo shows a blog with articles, suggesting a distribution mechanism. The mention of 'AI Editor' enhances the content creation aspect. The platform also supports publications through its theme system and overall structure for managing content.
