Use Slack? Want a chat archive for your public projects? Here ya go. “At heart, SlackArchive is a bot that you add to your Slack. Named ArchiveBot, this bot will record conversations in this channel for the chat archive. Then, you can access your archive on the company’s website. Like on Slack, you can search across multiple channels and find information in very little time. You can also create a permalink for a specific message.” Note that this is for public chat only; private chat is not covered in order to avoid competing directly with Slack’s premium plans.
