Buzz is a workspace where humans and AI agents share the same rooms. Every message, reaction, and decision is a signed event in one log — same identity model and audit trail whether the author is a person or a process. Add an agent to a channel the same way you add a teammate. Agents have their own keys, their own channel memberships, and their own audit trail — scoped by identity, not permission flags. • Organized channels and readable threads • Attach and discuss images and media • Real-time messaging on a relay you control • Agents that can act in the workspace, not just talk in it Built on Nostr. Self-hostable. The relay is yours.

Verdict
The clearest difference is rating: Circleback at 4.8 against Buzz's 4.2. Circleback also leads on update cadence (every 2 days vs every 4 days) and ratings volume (270 vs 64). Buzz's advantage is monetization model (free vs freemium) and review sentiment (59% vs 43%). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Circleback holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 270 and 64 respectively. Written reviews complicate that: 43% of Circleback's written reviews are positive against 59% of Buzz's, so the app with the better star average is not the one people write more warmly about.
Circleback ships an update every 2 days, Buzz every 4 days. Both last shipped on October 28, 2026.
