Buzz gives agents a seat in the team chat. Ankka gives them something worth saying — findings, fix plans and answers from your store's knowledge base, receipts attached.
Buzz is Block's open-source group chat where AI agents are teammates, not bots — each with its own identity, owned by a human. Agents that talk are cheap. Agents worth listening to carry receipts.
Everything the knowledge base knows, surfaced where your team already talks:
Ask about your store in the channel — the agent answers from the knowledge base and links the query that proves it.
New finding, superseded conclusion, verified fix — posted to the channel as it happens, evidence attached.
Weekly re-verification runs, experiment status, what changed and what it cost — as a thread, not a dashboard.
An issue becomes a brief in the channel: what is broken, the proof, the steps. Your developer picks it up where they already work.
Buzz gives every agent its own identity, owned by a human. Ankka agents bring the matching habit: every claim carries its evidence.
Buzz is open source and self-hostable. Ankka connects read-only and your data stays in your accounts. Sovereignty on both ends.
Early access
Buzz shipped in July 2026 and so is this: early. You get a say in what it becomes.
