Jack Dorsey Launches Buzz Combining Team Chat AI Agents and Git

Jack Dorsey has launched Buzz, a new platform that combines team chat, AI agents, and Git hosting into a single workspace. Announced via Block (formerly Square), Buzz aims to reimagine how developer teams collaborate by merging real-time communication with AI-powered automation and code management in one unified tool.

The platform integrates AI agents directly into team conversations, allowing developers to trigger code reviews, run automated workflows, and query project context without switching between tools. By bundling Git hosting alongside chat, Buzz competes with Slack, Discord, and GitHub by offering a tighter integration between communication and the development lifecycle.

For founders, Buzz represents an interesting bet on the convergence of productivity tools. If successful, it could signal a shift away from the current best-of-breed approach -- stitching together separate chat, code hosting, and AI tools -- toward unified platforms where AI agents are first-class participants in every team conversation.
