11### Work with more websites
12
13- **Use your browser:** Work in [Edge, Brave, Opera, or Vivaldi](https://learn.chatgpt.com/docs/chrome-extension)
14 as well as Chrome from the ChatGPT desktop app. Bring an open tab into a
15 ChatGPT Work or Codex chat and work with the website where you're already
16 signed in. Opera supports browser control but doesn't have side chat.
17
18- **Use a website's tools:** With [Site tools (WebMCP)](https://learn.chatgpt.com/docs/webmcp), ChatGPT
19 Work and Codex can use actions offered by a website in the desktop app's
20 built-in browser. For example, a document editor can provide tools to find
21 a section or add a comment. Update the desktop app and use GPT-5.6 Sol or
22 GPT-5.6 Terra. Site tools aren't available with GPT-5.6 Luna or in Enterprise
23 or Edu workspaces.
24
25- **Sign in through the cloud browser:** On eligible plans, continue a task
26 that needs a website account in ChatGPT Work on the web, iOS, or Android.
27 Follow the [sign-in request](https://learn.chatgpt.com/docs/browser?surface=web#web-sign-in-to-a-website)
28 and enter your details in the sign-in flow, not in the chat. This doesn't
29 connect your local browser profile. Website sign-in isn't available for
30 Enterprise or Edu workspaces.

48start when a supported event occurs in Gmail, Slack, or GitHub. Use an event
49trigger to triage new email, summarize channel activity, or act on pull request
50feedback without polling on a fixed cadence.
51
52Event-triggered tasks are available in ChatGPT on the web and mobile for
53eligible plans. Connect the relevant app and approve its requested access first. In managed
54workspaces, administrators can control access.
