Dots facts come from OpenAI’s launch post, the getting started help article and the Pro tiers page. OpenAI’s Pro tiers page listed Pro at $100, $200 or $500 a month on 30 Sep 2026. Munder Difflin facts come from the 0.5.3 release source.
Can ChatGPT dots run on my own computer?
No, a dot lives on OpenAI’s cloud computer with its own browser. You can open it at any time to watch or step in. If you turn on local access in the ChatGPT desktop app, the dot can also create local Work or Codex tasks, use local skills and drive your local browser. That access is off by default and you can revoke it.
Munder Difflin flips this. Each agent is a terminal session on your machine, in a folder you pick. Its identity, memory.md, inbox and outbox are files in its workspace. Why local first matters for AI agents goes further.
A dot keeps going while your laptop sleeps. A Munder Difflin office stops when the computer does.
Can I have more than one dot?
Not today. At launch each person gets one primary dot. OpenAI writes that “over time, we envision teams of dots working together” and that you will be able to add more dots in the future.
One dot can still work on several projects at once. In Munder Difflin you hire a team now: a reviewer, a tester, a writer, each with its own name, memory and engine. Michael, the orchestrator, reads the board, hands out tasks and keeps the team unblocked. Agents message each other through their outboxes, and the app routes each message to the right inbox. More in running an office of AI agents.
Which models can each one use?
Dots run on GPT-6 Astra. Munder Difflin 0.5.3 ships presets for Claude Code, Codex, Grok, Kimi Code, Gemini CLI, Antigravity, Qwen, OpenCode, Crush, Pi, Copilot and Cursor, plus a custom slot. Local models run through OpenCode, Crush or Pi, using Ollama or LM Studio, with no API key.
How do the controls and approvals compare?
Dots gate each action with Custom Rules; Munder Difflin gates inbound webhooks and throttles stuck agents. Custom Rules let you set each kind of action to act freely, act if approved in advance, ask first, or hand off to you. Auto review checks actions that touch accounts or share information, and saved passwords are used without showing them to the model.
Munder Difflin’s controls are aimed at a team of coding agents. A request from a webhook waits for your approval unless you loosen the mode. As of 0.5.3 the default is set in src/shared/triggers.ts:
export type TriggerMode = 'strict' | 'allow-all' | 'communication-only';
// ...
export const DEFAULT_TRIGGER_MODE: TriggerMode = 'strict';
When an agent needs a human decision, the card goes to the ASK ME board. A circuit breaker watches each agent for loops, repeated identical tool calls, error storms and spend over a cap you set, and escalates from a steering message to tighter limits. It only stops an agent if you turn on hard stop.
Where dots is better
You can reach your dot from your phone, in Slack or Teams, or call it by voice, and over 4,000 apps plug in. Proactive research brings you things you did not ask for, using read only access.
Where Munder Difflin is better
It is free and open source, with no region list. You keep the engines and subscriptions you already have. You get a team of named agents today, not a roadmap item. Memory is a markdown file you can read, edit or put in git. Files live on your disk; only what an engine reads goes to its provider. A local model keeps prompts on your machine, but agents can still fetch URLs, and anonymous usage stats stay on until you switch them off in Settings.
Is there an open source alternative to ChatGPT dots?
Yes, for work on code and files: Munder Difflin is MIT licensed. It does not try to match dots on personal errands across thousands of apps. Our ChatGPT dots alternatives list covers the others.
