A local-first AI team workspace that turns your existing ChatGPT, Claude, Gemini, DeepSeek, and Grok web sessions into a multi-agent discussion room.
OpenTeam is a Manifest V3 Chrome extension. It does not require model API keys and does not spend extra OpenAI, Claude, Gemini, DeepSeek, or Grok API tokens. Instead, it reuses the AI accounts you already have open in your browser, sends tasks to those web sessions, and gathers replies from different people and models into one shared team chat.
Use it for learning, research, and personal non-commercial experiments where one answer is not enough: product reviews, technical design reviews, content planning, personal decisions, multi-model comparison, and multi-step work that benefits from several AI roles thinking together.
OpenTeam is a sister project to OpenLink, an earlier browser extension I built around using the browser itself as the working surface. While building OpenLink, I already wanted a companion extension that could reuse signed-in browser sessions to talk with large language models and compare answers across models, but that idea stayed on the shelf while other work got busy.
The idea became concrete after I met Lu (YUANLU007), a news editor. In her writing workflow, she often needs to compare several AI systems, inspect how different models answer the same question, and use multiple perspectives for factual checks. That matched the original OpenLink idea closely, so OpenTeam became its sister project: a local browser workspace for sending one task to multiple AI web sessions and gathering their responses in one discussion room.

- ๐ซ 0 API token workflow: reuse AI website sessions instead of calling model APIs directly.
- ๐งฉ Multi-model discussion: coordinate Gemini, ChatGPT, Claude, DeepSeek, Grok, and other supported web sessions in one chat.
- ๐งโ๐ซ Built-in advisor library: start with 38 expert and thinking-style advisor templates, or create your own people.
- ๐ฃ Mention-based routing: use
@personto ask one member, or@everyoneto dispatch the same task to the whole team. - ๐ Independent and collaborative modes: compare isolated perspectives first, then let members reference, challenge, and build on each other.
- ๐พ Local-first storage: chats, people, messages, notes, highlights, and settings are stored in browser storage.
- ๐ค Agent control CLI: optional
openteamclisupport lets local agents create chats, add roles, post tasks, and wait for replies.
Each OpenTeam member is bound to an AI website session. When you send a message, OpenTeam builds a prompt from the chat mode, member persona, referenced messages, and shared context. The extension then delivers that prompt into the member's iframe-backed AI page and listens for the reply.

-> background service worker
-> AI site iframe
-> content script
-> AI webpage reply
-> OpenTeam message stream
Supported site types:
| Site | Common fit |
|---|---|
| Gemini | Long context, research, multimodal material |
| ChatGPT | General execution, tool-shaped workflows, fast iteration |
| Claude | Long documents, review, structured writing, careful reasoning |
| DeepSeek | Code, reasoning, Chinese-language work, cost-sensitive tasks |
| Grok | Current-events research, alternative phrasing, X/Grok web-session workflows |
These are practical defaults, not rankings. Actual quality depends on model versions, account plans, task type, and input material.
OpenTeam is an unofficial project for learning, research, and personal non-commercial use only. It is not affiliated with, endorsed by, or supported by OpenAI, Anthropic, Google, DeepSeek, xAI, or any supported AI website.
OpenTeam interacts with AI websites through user-authenticated browser sessions and DOM automation. Website changes, account rules, rate limits, anti-abuse systems, or terms of service may affect whether it works. You are responsible for reviewing and complying with the rules, policies, laws, and regulations that apply to your use.
Do not use OpenTeam for commercial products, hosted services, paid workflows, bulk automation, spam, scraping, bypassing access controls, bypassing paid access, or any activity that violates third-party terms or rights.
Use it at your own risk. The maintainers are not responsible for account restrictions, service interruptions, data loss, legal issues, or other consequences arising from your use. This notice is not legal advice.
Most users only need the browser extension:
git clone https://github.com/afumu/openteam.git
cd openteam
npm install
npm run buildAfter the build finishes, open chrome://extensions/, turn on Developer mode, click Load unpacked, select the generated dist/ directory, and then click the OpenTeam extension icon to open the team workspace.
Use this path if you want Codex, Claude Code, or another local agent to control OpenTeam chats. Install the CLI from npm, then install the agent skill:
npm install -g @afumu/openteamcli
npx skills add afumu/openteam --skill openteam-control
openteamcli daemon start
openteamcli doctorThe skills installer will ask which agent, scope, and install method to use. Use the GitHub command above for the public repository; if you are developing from a local checkout or unzipped source package, install the skill from the repository root instead:
npx skills add . --skill openteam-controlAfter installation, open the OpenTeam extension page and enable local agent control in settings. See OpenTeam CLI for more CLI details.
npm install
npm run devBuild the extension and load the generated dist/ directory from chrome://extensions/ with Developer mode enabled.
Useful checks:
npm run typecheck
npm test
npm run build
npm run verifynpm run verify runs type checking, unit tests, and a production build.
OpenTeam is local-first, but it needs browser-extension permissions that are worth reviewing before installation:
storage: save chats, people, notes, settings, and local state.tabs: locate and communicate with extension and AI-site tabs/frames.alarms: schedule runtime maintenance tasks.declarativeNetRequest: adjust response headers so supported AI websites can be embedded in the extension iframe workspace.clipboardRead/clipboardWrite: support copy and clipboard-based interactions.- Host permissions: allow OpenTeam to work with supported AI websites and embedded web sessions.
OpenTeam does not provide cloud sync. Your AI conversations are still processed by the AI websites you use, under their own account rules, usage limits, privacy policies, and terms of service.
- OpenTeam is Chrome / Chromium-first.
- AI-site adapters depend on page DOM structure, so website redesigns can break prompt sending or reply capture.
- The iframe workspace requires response-header changes through
declarativeNetRequest, which makes the permission surface heavier than a normal popup extension. - Built-in famous-person advisor templates are prompt templates inspired by public ideas. They are not real people and should not be presented as real participation.
- Medical, legal, financial, and other high-stakes outputs still require human judgment and qualified professional advice.
