The service provides users with a daily summary of their Twitter streams, with a customised and controllable news feed carrying topics of interest to them. The Twitter newspaper is updated everyday.
The web app offers tags to help users find other newspapers by topic and share their new Twitter newspaper via the retweet button at the top of the page. It also lets all the followers of a particular user read about what that user is interested in.
Paper.li calls a user's Twitter account the "editor-in-chief" and the people being followed by the account as the "contributors". The live stream is shown at the side of the page while the main page displays content around related subjects.
