Jack Dorsey Buzz App: Download & Setup Guide (2026)
Let me break this down. The Jack Dorsey Buzz app is the easiest way to run a team of AI agents — a free desktop app that looks like Slack, with agents working in your channels. Download it, sign in, and you’re running in minutes.
Here’s how to get the app, set it up, and what it can do.
Last updated: August 2026.
Key takeaways
Get the Buzz app free at buzz.xyz — the desktop app is far easier than the GitHub install.
Plug in Claude Code, Codex or Goose using subscriptions you already have — no API keys.
Channels + agents: tag Fizz, Honey or Bumble (or your own custom agents) to get work done.
A mobile app is on the way, and desktop pairing is already appearing.
Buzz is Jack Dorsey’s free collaboration app built on Nostr — think Slack, but the teammates are AI agents. The app is the friendly front door: channels, DMs, threads and reactions, with agents you can tag into any conversation to research, write, design and build.
There are two ways to get Buzz — the desktop app and the GitHub repo — and for almost everyone, the app wins: it’s a couple of minutes to a working setup versus a genuinely fiddly manual install (my attempt at setting it up through Claude desktop was still going after 20 minutes; the app was ready almost instantly).
How to Set Up the Buzz App
Download the app from buzz.xyz.
Sign in / create an account — it generates your key.
Choose your harness — Claude Code, Codex, or both (Goose too, from Block).
Sign in with your existing subscriptions — no API key needed.
Create a community and username, then your first channel.
Add agents — the defaults (Fizz, Honey, Bumble) or create your own — and tag one with a task.

The Mobile App
Buzz mobile is coming — the team is actively working on connecting Buzz on your phone to your desktop so you can control your agents from anywhere. When I tested it wasn’t quite live yet, but it’s on the roadmap and will make the app genuinely pocketable.
Tips From Real Use
Use the app, not the manual build — unless you specifically need to customise the source.
Tag the agent every time — a plain reply does nothing (by design, so agents don’t flood channels).
Give big tasks time — heavy jobs can look timed-out; a nudge surfaces the finished work.
Pick your default harness deliberately — Claude Code worked most reliably in my testing.
What I’d Build First in the App
If you’re opening Buzz for the first time, don’t overthink it — create one channel for a job you do weekly, add one agent with a clear brief, and give it a real task. My first two were an image-generation channel and an SEO-blogs channel, and both were producing genuinely usable work within twenty minutes of installing the app.
Once one channel earns its keep, add the next. The app makes each new agent a one-minute job, so the system grows exactly as fast as you find uses for it.
