Taco Bell announced Wednesday its testing TacoBot, a bot for Slack that allows users to order meals from within the chat application.

That's what trendy workplace chat vendor Slack is doing. The company is announcing an $80 million fund to invest in startups that build software that integrates with Slack.

Slack is rolling out a new AI bot to help users quickly summarize and search through their various chats and channels.

Using the new Concur Slack bot, users will, among other things, be able to submit receipts and enter their basic expenses, while their bosses can use the bot to approve them.
