Differ

Differ is an online publishing platform that allows writers to create and share content. It features a rich text editor, community feedback tools like likes and comments, and supports publications. It also has user profiles, a following system, and content categorization through tags and topics. While it explicitly states "no algorithms, no paywalls," it does have a "Personalized" feed based on followed writers and publications, and a "Trending" and "Featured" section, which acts as a form of content distribution and discovery. It also mentions a weekly newsletter from its parent company that features top articles, which can be considered a form of email newsletter integration. The platform is accessible via web browsers on any device, implying mobile access.
