Use the Chrome extension to let ZeroTwo control your Chrome browser. ZeroTwo can read or act on sites where you’re already signed in, such as LinkedIn, Salesforce, Gmail, or internal tools. To let ZeroTwo control its built-in browser instead, use @Browser. The built-in browser supports sign-in and keeps browsing work inside ZeroTwo without using your Chrome profile. ZeroTwo can also switch between tools as a task requires, using plugins when a dedicated integration is available, Chrome when it needs logged-in browser context, and the built-in browser for localhost.

​
Use ZeroTwo from Chrome

Open ZeroTwo beside the page you’re viewing to ask about the page or continue into tasks that can use its context alongside local files and connected apps. ZeroTwo can use context from your open tabs when a task needs it.
  1. Open the page you want to work with.
  2. Select ZeroTwo from the Chrome toolbar or Extensions menu. On macOS, you can also press Cmd+Shift+..
  3. Ask a question about the page or give ZeroTwo a task.

The panel stays with the tab where you opened it. Chats you start in Chrome are available in the ZeroTwo app, and you can open recent ZeroTwo chats in Chrome, so you can continue work in either place.

​
Bring tabs and selected text into a chat

Mention an open Chrome tab in the side chat when you want ZeroTwo to use that page as context. You can also highlight text on a page and bring the selection into your chat to ask about a specific passage without copying the whole page. To start from the page instead, right-click it and select Ask ZeroTwo. The side chat opens with the relevant page context so you can continue the request in Chrome.

​
Ask about a YouTube video

Open a YouTube video, then ask a question about it in the Chrome side chat. When captions are available, ZeroTwo can use the video’s timestamped transcript to explain, summarize, or answer questions about the content. Treat webpage content, selected text, and video transcripts as untrusted context. Review the page and any requested permissions before asking ZeroTwo to use or act on that information.

​
Set up the Chrome extension

In the ZeroTwo desktop app, open the Plugins Directory and install Chrome. Other Chromium-based browsers aren’t currently supported. Follow the setup flow to:
  1. Install the Chrome extension.
  2. Approve Chrome’s permission prompts.
  3. Open Chrome and confirm the ZeroTwo side chat loads.

​
Start a Chrome task from ZeroTwo

After the plugin setup is complete, start a new ZeroTwo Work or ZeroCode chat. ZeroTwo can use Chrome automatically when a task needs a website and you’re already signed in to Chrome. You can also invoke it directly in a prompt:
If Chrome isn’t already open, ZeroTwo can open it. Chrome browser tasks run in Chrome tab groups so the work for a task stays grouped together.

​
Control website access

By default, ZeroTwo asks before it interacts with each new website. ZeroTwo bases the prompt on the website host, such as example.com. When ZeroTwo asks to use a website, you can choose the option that matches the task and your risk tolerance:
  • Allow once to let ZeroTwo use the website one time.
  • Allow for this site so ZeroTwo can use the website again without asking.
  • Allow for all sites so ZeroTwo can use websites without asking.
  • Decline to prevent ZeroTwo from using the website.

​
Manage allowed and blocked websites

In the ZeroTwo desktop app, go to Settings > Computer Use, then select Manage next to Google Chrome to manage an allowlist and blocklist for domains. The allowlist contains domains ZeroTwo can use without asking again. The blocklist contains domains ZeroTwo shouldn’t use. Removing a domain from the allowlist means ZeroTwo asks again before using it. Removing a domain from the blocklist means ZeroTwo can ask again instead of treating the domain as blocked.

​
Allow for all sites ⚠️ Elevated risk

If you select Allow for all sites, ZeroTwo no longer asks for confirmation before using websites. Only choose this option if you trust ZeroTwo to use any website open in Chrome.

​
Browser history ⚠️ Elevated risk

Browser history can include sensitive telemetry, internal URLs, search terms, and activity from Chrome sessions on signed-in devices. If you allow ZeroTwo to access browser history, relevant history entries can become part of the context ZeroTwo uses for the task. Malicious or misleading page content can increase the risk that ZeroTwo copies this data somewhere unintended. ZeroTwo asks when it wants to use browser history. ZeroTwo scopes history access to the request, and history doesn’t have an always-allow option.

​
Data and security

​
Chrome extension permissions

Chrome asks you to accept extension permissions when you install the extension. The permission prompt may include:
  • Access the page debugger
  • Read and change all your data on all websites
  • Read and change your browsing history on all your signed-in devices
  • Display notifications
  • Read and change your bookmarks
  • Manage your downloads
  • Communicate with cooperating native applications
  • View and manage your tab groups
These Chrome permissions make the extension capable of operating browser workflows. ZeroTwo still uses its own confirmations, settings, allowlists, and blocklists before using websites or browser history during a task.

​
Memories

Computer Use follows your Memories setting. If Memories is on, ZeroTwo can use relevant saved memories while working in Chrome. If Memories is off, browser control doesn’t use memories.

​
What ZeroTwo stores from browsing

ZeroTwo doesn’t store a separate complete record of your Chrome actions from the extension. ZeroTwo stores browser activity only when it becomes part of the ZeroTwo context, such as text ZeroTwo reads from a page, screenshots, tool calls, summaries, messages, or other content included in the chat. Your ZeroTwo data controls apply to content processed in context. Avoid sending secrets or highly sensitive data through browser tasks unless they’re required and you are present to review each prompt.

​
Troubleshooting

If ZeroTwo can’t connect to Chrome, first confirm the website ZeroTwo is trying to access isn’t in the blocklist in Settings. If the website isn’t blocked, work through these checks:
  1. Update the ZeroTwo desktop app. If you have more than one ZeroTwo or ZeroCode desktop app installed, update each one or remove copies you no longer use.
  2. Close the ZeroTwo side panel, restart Chrome, then reopen the extension from the Chrome toolbar or Extensions menu. Confirm the side chat loads. If it doesn’t load or mentions a missing native host, remove and re-add the Chrome plugin from Plugins in the ZeroTwo desktop app, then follow the setup flow again.
  3. In the app, select ZeroTwo and turn on Work in the switcher, or select ZeroCode. Open Plugins and confirm that the Chrome plugin is on. If the plugin is off, turn it on and try the task again.
  4. Make sure you are using the same Chrome profile where the extension is installed. If you use more than one Chrome profile, install and enable the extension in the active profile.
  5. Start a new ZeroTwo Work or ZeroCode chat and try the Chrome task again. This can clear chat-specific connection state.
  6. Restart the ZeroTwo desktop app, then try again. If the extension still doesn’t connect, uninstall the Chrome extension, remove and re-add the Chrome plugin from Plugins, and follow the setup flow again.
  7. If the side chat loads but ZeroTwo still can’t use Chrome, run /feedback in the app and include the chat ID when you contact support.

​
Upload files

If a Chrome task needs to upload a file from your computer, allow the Chrome extension to access file URLs in Chrome:
  1. In Chrome, open the extensions icon in the toolbar, then click Manage Extensions.
  2. On the extension card, click Details.
  3. Turn on Allow access to file URLs.
After you change the setting, start the Chrome task again.
