Workplace Chat War: Jack Dorsey Drops Buzz to Ditch Slack and GitHub

Jack Dorsey just launched a new workplace chat platform called Buzz. The app aims directly at Slack and GitHub by combining team messaging with built-in artificial intelligence agents inside the exact same channels. Dorsey announced the project on X, describing Buzz as an open source, decentralized, model-agnostic platform built to give teams full control over their workplace tools.

The app comes out of Block, the tech firm behind Square and Cash App. Dorsey wants to reduce how much modern teams depend on proprietary communication silos like Slack. Today, tech workers waste constant energy switching between chat apps, GitHub code repositories, and external AI dashboards. Buzz attempts to collapse those fragmented tools into one unified workspace.

Inside Buzz, human developers and digital agents sit in the same chat rooms. Instead of running external software to query an AI model or check code changes, team members talk directly to digital bots right alongside human coworkers. These agents can handle GitHub project tasks, analyze code updates, and answer technical questions without making users open another browser tab.

Because Block made Buzz fully open source, developers can download the complete codebase from GitHub today. Companies can host their own private servers, customize features, and maintain total ownership of their corporate data. That self-sovereign setup appeals to engineering teams tired of paying monthly seat fees to big cloud providers who lock down platform data behind closed walls.

Dorsey is not the only builder trying to rethink workplace communication around AI. Tech leaders across Silicon Valley are building tools to bring digital workers into daily workflows. For example, Georgios Konstantopoulos, partner and CTO at Paradigm, recently introduced Centaur. That project acts as a virtual employee running inside Slack or through direct API connections.

While tools like Centaur attempt to upgrade existing software by plugging into Slack, Dorsey wants software teams to abandon closed ecosystems altogether. He envisions a future built on open protocols where teams run their own infrastructure and pick whichever AI models best fit their needs.

Buzz is still in its early stages of development. Block released free desktop builds for macOS, Windows, and Linux, alongside the public GitHub repository. Moving a large corporate workforce over to Buzz right now might prove premature while the app matures.

However, the arrival of open tools like Buzz signals a clear shift in software development. As automated agents take over routine coding, documentation, and operational tasks, chat platforms must evolve beyond basic text messaging. Buzz provides a preview of a workplace where humans and AI agents build software together as equal teammates in real time.
