Jack Dorsey is taking on Slack with Buzz, a group chat platform for teams and their AI agents

Jack Dorsey，也就是Twitter和Block的创始人，最近推出了一款名为Buzz的新聊天软件，目标直指Slack和GitHub。这款应用最吸引人的地方在于，它把人类员工和AI助手放在同一个聊天室里，团队不仅能互相沟通，还能直接调用AI代理帮忙干活，所有工作流程都整合在一个窗口里。通俗点说，Buzz长得有点像Slack，但内置了原生AI代理。以前你要在Slack里聊天，再用GitHub管理代码，不同工具来回切换很麻烦。现在Buzz把这些全打通了，你可以在聊天面板里直接和AI说“帮我合并这个代码分支”或者“整理一下会议纪要”，AI会自动完成。而且它是开源的，意思是技术团队可以自己修改代码，想加什么功能就加什么，完全定制。同时Buzz强调去中心化，用户数据自己掌控，不依赖大公司服务器。对普通用户来说，如果你所在的小团队正在大量使用AI代码助手或自动办公工具，Buzz能让你少装几个软件，工作更集中。不过目前它还是早期版本，稳定性有待考验，不建议主力团队立刻迁移。但可以关注它未来如何改变AI与人协作的方式——未来工作中，AI可能不再是后台工具，而是和你一样在聊天室里“说话”的同事。

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. we're launching BUZZ!a new groupchat platform for teams of people and agents of all sizes, built to reduce our dependency on slack and github. model-agnostic, decentralized, self-sovereign, and open source. 🐝https://t.co/8IaMVeTQNo— jack (@jack) July 21, 2026 As startups increasingly rely on AI agents to get work done, it can be challenging for employees to collaborate on various tasks across different platforms. Buzz’s utility is that it merges several different workflows into one workspace. It looks a lot like Slack, but with native AI agents and the ability to manage GitHub projects all from the same window. Since the platform is open source, developers can make their own Buzz instance feel more customized to the needs and workflows of their specific team. If a team needs a new feature, they can build it and deploy it on their own, since they have full access to the source code.

Paradigm partner and CTO Georgios Konstantopoulos recently unveiled a similar open source product called Centaur, 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. Read our blog to get a deep dive on Why Centaur and How It Works.My TL;DR is that Centaur is the best way to AGI pill your team and to 100x your team's productivity.There's a lot of room for improvement for agents that live in Slack and can do more work than just coding for…— Georgios Konstantopoulos (@gakonst) May 21, 2026 For newer startups that are using AI agents and don’t have an established presence on Slack, Buzz (or its competitors) could be worth investigating. But Buzz itself admits that it is in its “early stages,” so it’s probably not a good idea to port your team over just yet. var playerInstance_jwplayer_6a6019b6e698f = jwplayer( "jwplayer_6a6019b6e698f" ); playerInstance_jwplayer_6a6019b6e698f.setup({ playlist: "https://cdn.jwplayer.com/v2/media/DxHIIVx3", }); Buzz’s free desktop app is available now for macOS, Windows, and Linux, and the code for the app has been uploaded to GitHub.
