The PaperBot is a Slack bot that creates a daily email digest from your #channels. Flagging channels is easy, you simply invite @paperbot to your channels. Every day, the bot will quietly collect links and prepare a "newspaper" delivered by email of channel content posted by you and your team.

Team members can customize their daily digests (hiding channels, etc). This is a 100% free bot with no limitations on channels, users or messages.
