What Buzz is built for
Buzz combines team communication, agents, workflows, and Git activity around a signed event history. Its open source code gives teams the option to operate their own relay. Block's Buzz repository
Where Them AI fits
Start with the company record.
Consider Them AI when your starting point is reusable company knowledge: a decision with its reasoning, an owner who can review it, and a skill another person or agent can use. Mac-only for now. Free during the beta (invite-only).
How Rooms and memory fit togetherWhen to choose Buzz
A different starting point.
Consider Buzz when source access, control over deployment, and developer workflows are priorities. A hosted community is also an option if you do not want to operate a relay yourself.

| What matters | Them AI | Buzz |
|---|---|---|
| The shared record | Company memory is organized into facts, entities, decisions, and processes, with sources, owners, and review status. Rooms hold shared work; human access is organization-wide in the current beta. | Messages, reactions, workflow activity, review approvals, and Git events share a signed event log. The repository documents search and audit logs across that work.Buzz workspace and event model |
| Agent participation | Agents use MCP to search approved memory, retrieve skills, and post to rooms. Their work can draw on a common company reference without making Them AI their execution environment. | Agents have their own identities and access to shared work. Buzz documents a CLI and an ACP harness for Goose, Codex, and Claude Code, plus workflow triggers and Git tools.Buzz agent tools |
| Deployment and access | Them AI is currently a Mac app in an invite-only beta. The waitlist asks for a business email so teams can request access. | Buzz supports Block-hosted communities and independently operated relays. Its desktop app is available for macOS, Windows, and Linux. Each relay keeps its community's content separate.Buzz hosted and independent communities |
A practical evaluation
Keep the lesson after an incident
An incident leaves a trail of messages, fixes, and decisions. The next question is what the company should reuse: the cause, the recovery method, or a change to its process. In a Them AI evaluation, give that lesson an owner, connect its sources, and review the memory and skill your team wants to retain.
Questions worth asking.
Do I have to host Buzz myself?
Does this mean Buzz has no review or governance?
