Jack Dorsey’s Block takes on Slack with Buzz, a workspace for humans and AI agents

What it does

Block, Jack Dorsey’s fintech company behind Square and Cash App, has launched Buzz, an open-source workspace designed for teams that include both humans and AI agents. Buzz creates channels where people and AI bots collaborate side-by-side. Unique to Buzz, each AI agent operates with its own portable identity, allowing it to move across different workspaces while maintaining consistent credentials and history. This approach blends human communication with automated assistance in a shared environment.

Why it matters

Buzz aims to challenge Slack by embedding AI agents directly into workspace channels rather than relying on add-ons or separate automation tools. For businesses, this means AI can participate as a peer in conversations, handling tasks like information retrieval or decision support more seamlessly. The portable AI identity reduces friction for organizations wanting to integrate and manage these agents consistently across projects. For builders, Buzz signals a push toward native AI collaboration rather than bolt-on AI features, which can improve workflow efficiency but also raises questions about how identities and permissions get managed at scale.

Who it is for

Buzz targets teams and organizations looking for flexible collaboration tools that blend human and machine input in one place. Builders and integrators interested in open-source AI-driven workflows will find value in Buzz’s transparent, portable identity system for AI agents. Businesses that want to experiment with embedding AI helpers directly in communication channels might consider Buzz as an alternative to traditional chat platforms combined with separate AI bots.

The catch

Buzz is still emerging in a space crowded with established players like Slack and Microsoft Teams, which are rapidly integrating AI features themselves. The success of Buzz depends on adoption by teams willing to allow AI agents to participate fully in shared channels. Managing AI identities and security in these environments will require clear operational practices. Since Buzz is open source, organizations may face additional responsibility for setup, maintenance, and governance compared to proprietary platforms.

What to watch next

Look for how Block evolves Buzz’s AI agent capabilities and identity model over time, especially regarding security and ease of integration. Adoption rates among early teams will reveal how practical it is to work with AI agents as peers. Watch if bigger competitors accelerate their native AI collaboration tools, forcing Buzz to differentiate further by features or developer-friendly openness. Block’s fintech background could also influence potential use cases combining payments, finance, and AI automation inside Buzz.
