(2026-07-22) Jack Dorsey Is Taking On Slack With Buzz A Group Chat Platform For Teams And Their Ai Agents Techcrunch

Jack Dorsey is taking on Slack.com with Buzz.xyz, a group chat platform for teams and their AI agents. Twitter and Block co-founder Jack Dorsey announced a new app on Tuesday called Buzz. Positioned as a challenger to Slack and GitHub, Buzz is a group chat platform for the workplace that puts humans and their AI agents in the same conversations.

Dorsey wrote on X that Buzz is “model-agnostic, decentralized, self-sovereign, and open source.” This product seems to be more than just a Dorsey passion project. According to its website, Buzz was built by Dorsey’s company Block, which also operates products like Square, Cash App, Afterpay, and Tidal.

It looks a lot like Slack, but with native AI agents and the ability to manage GitHub projects all from the same window

Dorsey isn’t the only entrepreneur trying to pursue AI-native alternatives or additions to Slack. Paradigm partner and CTO Georgios Konstantopoulos recently unveiled a similar open source product called Centaur.run, which he describes as a “virtual employee” that runs either inside of Slack or via an API.

“There’s a lot of room for improvement for agents that live in Slack and can do more work than just coding for teams. In the enterprise setting, this means that you’ll want to self-host for security and control, and you want people to use it in Slack,” Konstantopoulos wrote on X.

Buzz’s free desktop app is available now for macOS, Windows, and Linux, and the code for the app has been uploaded to GitHub.
