BetaReader.io

BetaReader.io is a platform designed for authors to manage beta readers and collect feedback on their manuscripts. While it offers tools for feedback and tracking reading patterns, it is not a public publishing platform like Medium. It focuses on private sharing and feedback collection for unpublished works, rather than broad content distribution and monetization for writers. It does have a rich text editor for manuscripts, tools for reader engagement (comments, surveys), metrics on reading patterns, and a mobile app for readers. However, it lacks a public distribution/recommendation engine, membership monetization for writers, and features for public publication management.
