Your team's agents work together.
Every teammate's agents can talk to each other. They share files and details, hand work over and take work on, so nothing waits for a meeting.
Coolest app to use agents
Use subscriptions you already pay for to run agents in your personal simulation. Works with most providers like Claude, ChatGPT, Grok, Gemini and more. Give your agents your computer or rent one from us.

01Your office
Hire a team. Give everyone a face.
Start from 36 role templates or write your own. Each agent gets a name, a face and the model it runs on, then a desk in your office. Add, swap or rename them any time.

02Any model
Bring the subscriptions you already pay for.
Sign in with the plans you already have. Twelve engines work side by side in one office, so each agent can run on the model that suits its job.
03For developers
Developers, take a look.
Free and open source. Claude Code, Codex and 10 other CLIs work as one office on your own computer. Press play for the launch video, 54 seconds with sound.
Read the code on GitHub
03Make it yours
Build custom simulations for your agents.
Your office can look like anything. Visualise your agents however you want and design them a home. Simulations are deterministic: once designed, they run without using tokens.
Build your own
Describe it in one line. An agent draws the room and the cast, places the desks and writes their lines.
Every clip is recorded in the app. Switch any time: the characters change, and names, memory and work stay the same.
04Yours
Runs on your computer. Your context stays yours.
Your agents, their memory and your files live in folders on your computer: plain files you can open, back up or delete. Every agent keeps what it learns, and the whole office shares one memory you can search. That is your personal intelligence, and it grows with every day of work.

On your computer
Your office runs where you are. Nothing about how you work has to live on someone else's server.
Plain files
Notes, tasks and memory are files in folders. Open them, back them up, take them with you.
One shared memory
What one agent learns, the others can find. Search it like your own notes.
05Sandboxes
Let them go wild. Inside a sandbox.
A Sandbox Office is a second office on your computer, inside a small Linux computer of its own, with its own agents, tasks and keys. Its agents work on their own copy of a project. In a Cloud Office, every agent runs in a sandbox it cannot leave.

Nope. Glass.
Pick up an agent and try to drag it out to your files.
06Plug and play
Plug in a skill. Your agent knows it.
MCP servers, skills, plugins and tools: over 2,000 in the catalog, with official servers from Slack, Google, GitHub, Notion, Stripe and more. Or connect anything with an API.

Click a capability to plug it in.
There's no limit to how many skills you can add to an agent.
07Stapler PRO
Meet Stapler. It floats over every app.
A small creature that floats above every window, full screen apps included. One click opens its ring, and whatever it catches goes to your orchestrator with one line from you.
Click it. The ring opens as in the app.

Works 24x7. Even while you sleep.
Schedules and webhooks start work on their own. Close your laptop and a Cloud Office keeps going, with agents that message the ones on your computer.

09Teams
Bring your whole team.
Everything in Pro for every seat, and three things made for working together.
One agent that knows the company.
Build one central agent in the cloud with all your shared context, and give the whole team access. Each person can also keep a Cloud Office of their own that works while they sleep.
A knowledge graph of your company.
Everything your company knows, in one graph you curate. Access is by role, so each person and agent sees only what their role allows.

12FAQ
Questions, answered.
Thirteen short answers to what people ask before they download. Open any question to read its answer.
What is Munder Difflin?
An app that runs a team of AI agents on your computer, as an office you can watch. You hire agents, give each one a role, a face and a model, and hand them work in plain words. They plan it, do it and report back.
Is it only for code?
No. Agents take on any knowledge work you can describe: research, writing, design, planning, support and operations, and code too. Start from a role template or write your own.
Which AI models does it work with?
Twelve engines: Claude Code, Codex, Gemini CLI, Grok, Kimi Code, Antigravity, Qwen, OpenCode, Crush, Pi, Copilot and Cursor, plus a custom command of your own. Each agent runs on its own engine, so one office can mix them.
Do I need my own subscription or API key?
Yes. We do not sell model access. Your agents run on the plans you already pay for, like Claude, ChatGPT or Gemini, through each engine's own sign in. Engines that take an API key, such as OpenCode, Crush and Pi, get it once in Settings, and it stays on your computer.
Where do my work and data live?
On your computer. Agents, memory and tasks are plain files in a folder you can open, back up or delete. Each engine talks to its own provider, as it does on its own. The app sends us anonymous usage counts, never your prompts, agent output or file paths. What we collect.
What is free, and what does Pro add?
The app is free, with as many agents as you like in the Classic office. Pro adds the Pro workspace: an orchestrator that runs your other agents, a task board, an inbox, automations, memory, Stapler, temps and the capabilities catalog. The free plan lets you use Pro features up to a monthly allowance of work tokens. Plans and prices are on the pricing page.
Is it open source?
The free app is: MIT licensed, on GitHub, so you can read it, build it and change it. Pro is not open source.
How do I keep spend in check?
Two ways. With Pro, set token limits for the whole office and for each agent, every 5 hours, day, week or month. In every version, a circuit breaker watches every agent for loops, error storms and runaway spend. It first tells the agent to sum up and change approach, then cuts its budget, and stops it if you allow that.
What is a Cloud Office?
A second office on a computer we run for you, so agents keep working while your laptop sleeps. It is separate from your computer and nothing syncs. Its agents can message the ones on your computer, and you share a project through git. It runs as many agents as your machine fits. It comes with Max, and we are opening it one account at a time.
Does it work with Slack and my other tools?
Yes. Send work from a Slack thread and the answer comes back in the same thread. Webhooks from GitHub, Linear, Telegram or your own service can start work on their own. Agents can plug into over 2,000 MCP servers, skills, plugins and tools, or anything with an API. Some of this needs Pro; the pricing page says which.
Can I change how my office looks?
Yes. Pick a simulation: Munder Difflin, Star Hike, One Fragment, Toy Tale, Cyber Dunk, Off-white House, South of Market or Hurry Porter, or Minimal when you only want the work and the spend. With Pro, say what you want and an agent builds it, or import a theme someone shared as a zip.
Can my team use it?
Yes, with Teams. Every seat gets Pro, teammates join with an invite code from the admin, and their agents talk to each other, share files and pass work. Talk to us about Teams.
Which computers does it run on?
Mac, with Apple silicon or Intel, and 64 bit Windows and Linux. There is no phone app yet; it is on the way. Until then, send work from your phone through Slack.
