Jack Dorsey bets that the future of AI-powered teamwork won't be just another chatbot window.
Block’s CEO is backing Buzz, a new self-hosted collaboration platform that uses Nostr to create a workspace where humans and AI agents can work together. The idea is simple: instead of AI tools being temporary assistants, they become participants within a shared environment.
Buzz combines ideas from Slack, GitHub, project management tools, and AI assistants into one workspace. Behind the scenes, it uses Nostr-style signed events, with messages, reactions, workflow actions, code changes, and approvals stored as part of the event stream itself.
The platform is based on the idea that AI agents should have their own identities. An AI agent will be able to join a channel, participate in discussions, review code, execute workflows, and leave behind an audit trail of what it did.
This is a different approach than the way most AI assistants work today. Many tools are designed around one-on-one conversations where users ask questions and receive answers. Buzz is trying to make AI agents permanent members of a team.
Block describes the concept as “agents are members, not bots.”
This could become increasingly important as companies start to give AI systems more responsibility. If an agent is going to review code, handle bugs, or help manage projects, organizations will likely want to know exactly what it did and why.
Buzz attempts to solve this problem by giving AI agents their own keys and identities. Each action can be linked to a specific AI agent, just like with humans.
Perhaps the biggest idea is to replace the collection of disconnected tools that many teams use today. Developers could discuss a feature on Slack, track issues on Jira, manage code on GitHub, check builds through CI systems, and use separate AI tools for assistance.
Buzz wants all of these activities to happen in the same space.
The platform already supports channels, instant messaging, media, search, audit logs, Git events, and workflows. It also includes a desktop app and command-line tools designed specifically for AI agents.
The Nostr Foundation is what makes Buzz unusual. Instead of relying entirely on a central service, users will be able to run their own “repeater” and control their own workspace. The project is open source under the Apache 2.0 license.
Buzz will likely appeal first to developers, open source communities, and people already interested in decentralized technology. Whether it can reach beyond that audience will depend on how useful the platform is in everyday work.
But the problem Buzz is trying to address is real. As AI agents become more capable, companies will need better ways to manage their identities, actions, and collaboration with humans.
Dorsey’s bet is that Nostr can become part of that foundation. Buzz isn’t just about adding artificial intelligence to a chat app. It’s an attempt to rethink what a workplace might look like when humans and agents work side by side.
Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
