Jack Dorsey's Buzz: Clearly Explained (and how to use it)
Jul 28, 2026 · 38:44
Greg Isenberg and Vinny explore Buzz, an open-source agent-native chat app from Block (Jack Dorsey's company) that treats AI agents as first-class team members in a Slack-like interface. The central claim is Buzz's openness—built on the Nostr protocol—lets users swap agent harnesses (Claude Code, Codex, Goose) without losing context, and all chats, projects, and decisions carry through each swap. Vinny demos building a CRM app with Wasp framework deployed to Railway and a tweet leaderboard that pipes daily stats into a channel via public API, showing agents can work end to end. He recommends pinning agents to specific models (Fizz to FAINVL, Honey to Sonnet) and creating a chief agent officer for delegation. Greg notes Buzz is early but argues it's worth trying to learn the future of agentic work, where context is the foundation and openness prevents vendor lock-in. The episode ends with Vinny hinting at deeper open protocol integrations to come.
