Jack Dorsey is taking on Slack with Buzz, a group chat platform for teams and their AI agents

Jack Dorsey announced Buzz, a workplace group chat platform from Block that aims to reduce reliance on Slack and GitHub. The app combines team messaging, AI agents, and GitHub project management in one open-source, model-agnostic workspace.

Buzz reflects a broader shift toward AI-native collaboration tools as companies look to embed autonomous agents directly into daily workflows. Its open-source and decentralized positioning could appeal to technical teams that want more control than traditional enterprise chat platforms provide.
