Known

Known is an open-source social publishing platform designed for individuals and groups to create and share various forms of content, including blog posts, photos, and media. It emphasizes user ownership of content and provides tools for multi-author collaboration, rich text editing, and social interaction.

Known is an open-source social publishing engine that allows individuals and groups to create and share various types of content, similar to Medium's core offering. It explicitly mentions a 'HTML & Rich Text Editor' (rich-text-editor), 'Multi-Author' functionality which aligns with 'Publication Management' (publication-management), and 'Decentralized Indieweb' features that allow sites to 'respond to each other, bookmark each others' content and leave comments on each others' posts' (community-feedback-tools). It also supports 'User Profiles & Following' through its social publishing nature and 'Tags & Topics' via hashtags. Email notifications are mentioned, which can be a form of 'Email Newsletter Integration'. The platform is responsive, implying 'Mobile App Access' through a web interface, and supports 'Social Sharing & Embedding' through syndication to social networks and feeds. While it doesn't explicitly detail a recommendation engine or monetization model like Medium, its focus on content creation, sharing, and community interaction makes it a strong match for many features.
