Jack Dorsey launches Buzz, a team chat platform for humans and AI agents

Jack Dorsey, the co-founder and former CEO of Twitter, has launched a new group chat platform called Buzz, positioning it as a competitor to Slack. Buzz is designed for workplace communication, but with a distinctive twist: it allows both human team members and their AI agents to participate in the same conversations. The platform aims to integrate artificial intelligence directly into daily team interactions, enabling AI agents to contribute alongside people.

The launch affects businesses and teams that rely on messaging apps for collaboration, particularly those already using or considering AI tools. By putting AI agents in the same chat threads as humans, Buzz could change how teams delegate tasks, share information, and automate workflows. This matters because it represents a shift from traditional chat apps that treat AI as a separate tool or bot, to a model where AI is a native participant in group discussions.

Dorsey announced Buzz on March 4, 2025, though the platform's availability and pricing details have not been disclosed. The move comes as Dorsey continues to explore new technology ventures after stepping down from Twitter (now X) and focusing on Block, his payments company. Buzz enters a market dominated by Slack, which Microsoft acquired in 2021, and other workplace chat tools like Microsoft Teams and Google Chat.

No specific numbers of users or beta testers were provided in the announcement. The next steps for Buzz are unclear, but given Dorsey's track record, the platform may undergo a public beta phase before a wider rollout. The success of Buzz will likely depend on how well it integrates AI agents into real-world team workflows and whether it can differentiate itself from established competitors.
