Every tool your team uses is multiplayer. Except AI.

Poly is multiplayer AI: a shared room where your team works with one AI agent, together. Everyone sees what was asked, anyone can answer or approve, and the decisions stay with the team.

The problem

You plan together. Then everyone prompts alone.

Your team is all-in on AI. But every session is private, so the work gets faster while the team gets further apart.

The context stays in private chats

What was asked, what was tried, what got rejected. It all builds up in five separate sessions that nobody else can see.

You become the middleman

You paste the output into Slack, explain how you got there, and answer questions about work the agent did.

The reasons disappear

The work gets merged. The understanding doesn't. A month later nobody remembers why the decision was made.

How it works

One room. One agent. The whole team.

Poly is a multiplayer AI coding workspace: your team and one agent, in one place, live.

01

Everyone sees the same thing

Every prompt, every answer and every change lands in one timeline, live. Nobody needs a recap, because nobody was out of the loop.

02

Anyone can answer, approve or steer

When the agent has a question or wants to do something big, it asks the room. Whoever knows the answer gives it. Nothing important happens without a yes.

03

The decisions stay with the team

Every call the team makes is kept with who made it and when. A new teammate reads it in thirty seconds. The agent remembers it next time.

The models

Every frontier lab. One room.

Claude, GPT, Grok, Kimi and Muse, side by side. Each person picks their own. Switch mid-conversation and the room carries the context across.

  • Claude
  • GPT
  • Grok
  • Kimi
  • Muse

One free model from every lab. No API keys.

When to use it

For the moments you'd normally screen-share.

Keep your solo sessions for solo work. Open a room when the work is shared.

PM + engineer

Speccing a feature

Notes go in, a spec comes out, and the engineer pushes back in the same room before anything is built.

Marketing + founder

Planning a launch

Brief, headlines and images in one place, with the founder answering the judgment calls as they come up.

Founder + engineer

Building a prototype

One of you knows the customer, one of you knows the code. Both of you steer, and both of you watch it take shape.

Questions

What is multiplayer AI?

AI a group uses together: everyone works with the same AI agent in one shared place, sees what was asked and what it did, and can steer it, instead of each person prompting alone. That's Poly.

Is it really multiplayer, or just a shared history?

It's live. Everyone in the room sees prompts, answers and changes as they happen, and anyone can answer the agent's questions, approve what it does next, or stop it mid-flight.

Which models can we use?

Claude, GPT, Grok, Meta's Muse and Kimi, in the same room. Each person picks their own model and thinking effort, and nobody needs an API key. Every lab has a free model — Sonnet 5.5, Haiku 5.5, GPT-6 Luna, Muse Spark 1.3, Kimi K2.7 Code and Grok Build; any plan or top-up unlocks the rest — Opus 5.5, Fable 5.1, GPT-6 Astra, GPT-6 Sol, GPT-5.6 Terra, Kimi K3 and Grok 4.7.

Do we have to stop using Claude Code or ChatGPT on our own?

No. Keep your solo sessions for solo work. Poly is for the work you'd do together anyway — the moments you'd normally screen-share.

Does it work with code we already have?

Yes. Connect a GitHub repository to a room and changes go straight into it, attributed to whoever made them. Push to a branch or open a pull request when you're ready. Or start from nothing.

What if the AI breaks something?

Every step is saved with a readable list of exactly what changed, and any step can be undone with the Undo button right under it. You can also require a yes before the agent edits anything at all.

What does it cost?

It's free to start, with no card. You pay only for the AI you run: plans from $20/month and top-ups from $5. Watching, chatting and approving in a room are always free.

Do you have a plan for teams?

Yes, in early access. Poly for Teams adds organizations, a room per team with its own playbook, shared team memory the agent reads on every turn, cross-team rooms, and usage by team. Book a demo or email support@usepoly.co.
