Instapaper

Instapaper is a 'read-it-later' application that allows users to save web pages and articles for offline reading. It provides a simplified, distraction-free reading experience across various devices, including mobile and Kindle. Users can organize saved content into folders and highlight text.

Instapaper is primarily a 'read-it-later' service, which allows users to save web pages for offline reading in a simplified, distraction-free format. While it offers a clean reading experience (akin to a rich text editor for saved content) and some organizational features like folders (which can be seen as a form of tagging), it lacks the core publishing and monetization aspects of Medium. It doesn't provide tools for writers to create and publish original content, nor does it have a recommendation engine for new content discovery beyond what a user saves. There's no explicit mention of a membership monetization model for content creators or detailed reader engagement metrics for published articles, as Instapaper's focus is on personal consumption rather than public distribution and interaction.
