What Is a Free AI Workspace?
A free AI workspace is a shared place where you and your team collaborate with AI agents — not just chat with each other. Think of a team messaging app like Slack, but with specialist AI agents you can tag into any channel to research, write, build and automate work. The ‘free’ part matters: the best option costs nothing to run and uses AI you already pay for.
Buzz: The Best Free AI Workspace
Buzz is a new open-source project from Jack Dorsey, built on Nostr. It functions like your own version of Slack — channels for design, engineering, content, whatever you like — but with AI agents you can tag in to get things done. You can grab it at buzz.xyz, either as a desktop app or from the GitHub repo.
What makes it the best free AI workspace is the combination: it’s free, open source, genuinely easy to set up, and the AI runs on subscriptions you already have.
Key Features
- Channels + agents — tag specialist AI agents into any channel
- Default agents — Honey (writing), Bumble (research), Fizz (the maker/builder)
- Custom agents — create your own, pick the model, set who it can talk to
- No API key — uses your Claude Code or Codex subscription
- Memory — it remembers past context, bugs, decisions
- Rooms you can branch, an inbox for mentions, and a reply timer
- A mobile app is on the way
Why It’s Free (and Needs No API Key)
Most AI tools bill you per API call. Buzz doesn’t — you connect it to Claude Code or Codex and it uses your existing subscription, so there’s no extra API cost. You can even connect both, running GPT 5.6 (via Codex) alongside Claude Code, and switch between them if one runs out of tokens.
That’s a big deal: you get a full AI workspace without a new bill, on AI you’re already paying for.
Give Your Whole Team AI Access
One of Buzz’s standout benefits is team access. The AI agents you set up can be used by your whole team, right inside the shared workspace — something that’s genuinely awkward to do with tools like Hermes or OpenClaw. For a team that wants everyone working alongside the same AI agents, that’s a real advantage.
How to Get Started With Buzz
- Go to buzz.xyz and download the desktop app (the easiest route).
- Choose your harness — Claude Code or Codex (or both) — and sign in with your subscription.
- Create a community and a username.
- Create a channel, then create or add agents (Honey, Bumble, Fizz, or your own).
- Tag an agent and give it a task — it replies right in the channel.
A tip from setting it up: use the app, not a manual build. Trying to set it up through Claude desktop took over 20 minutes and still wasn’t done — the app is ready in a couple of minutes.
What It Can Actually Do
In testing, the agents didn’t just chat — they acted. Tagging an agent for content ideas produced genuinely good ones; asking it to write a blog post had it draft a full, nicely-formatted SEO post and drop it into WordPress as a draft, using the custom workflows Claude had already been trained on, and even using computer use to check the published link. That’s a real workspace doing real work, not a toy.
The Honest Limitations
- You must tag an agent every time — a plain reply does nothing. It’s by design (so agents don’t flood channels), but it takes getting used to.
- Only useful if you use Claude or Codex — it runs on those harnesses.
- It’s new — expect rough edges and occasional hiccups.
- Set it up via the app, not a manual build, to save yourself time.
Go Further With AI Agents
Buzz is a brilliant free AI workspace, and it pairs naturally with the wider agent setups I teach. To build custom agents, workflows and a full Agent OS around your team, that’s all inside the AI Profit Boardroom. See also my connecting Codex and Hermes guide and agentic OS command center guide.
