Jack Dorsey, co-founder of Twitter and Block (formerly Square), has launched Buzz, a new group chat platform designed for workplace teams that integrates human users and AI agents into collaborative conversations. Buzz aims to rival Slack and GitHub by providing a unified workspace where teams can manage workflows alongside AI tools. Dorsey describes Buzz as model-agnostic, decentralized, self-sovereign, and open source, adding that its open architecture allows teams to customize their experience and build new features tailored to their unique needs. The platform currently has a free desktop app available for macOS, Windows, and Linux, with the source code publicly hosted on GitHub.

Buzz’s functionality centers on streamlining team collaboration by combining communication and project management with integrated AI agents. These agents can assist with various tasks, including managing GitHub projects directly within the chat interface, aiming to reduce the fragmented nature of current workplace tools. The move reflects a growing trend where AI is embedded into productivity software, helping companies better leverage automation and intelligent assistants for efficiency. Despite its early-stage status, Buzz is positioned as a promising option for startups and teams looking for AI-native communication platforms outside established products like Slack.

Other developers are also exploring AI-centric alternatives in this space. Georgios Konstantopoulos, CTO at Paradigm, recently introduced Centaur, an open source Slack plugin bringing virtual AI employees into team environments, emphasizing self-hosting for security and control. Konstantopoulos sees room for improvement in AI agents that live inside Slack, particularly for enterprise users who prioritize data privacy and customization. Together, these initiatives highlight an emerging ecosystem of AI-driven team collaboration tools offering more flexibility and security than incumbent platforms.

While Buzz and competitors like Centaur offer exciting new possibilities, experts caution that these solutions remain in early development. Teams heavily reliant on Slack and other legacy tools should approach migration cautiously. However, as AI agents become increasingly central to workplace productivity, platforms that seamlessly integrate human and machine collaboration in a customizable, open, and secure environment could shape the future of team communication and project management. Jack Dorsey's Buzz could be a significant player in this evolving market.
