Do Chrome Extensions Work in ChatGPT Atlas? Full Guide

Looking for a Chrome extension for ChatGPT Atlas? OpenAI retired its AI-native browser on August 9, 2026, but it has a replacement for its AI-powered browsing features.

The good news is that you don't need a separate browser to use ChatGPT while browsing. OpenAI now offers a ChatGPT Chrome extension for working with webpages, alongside ChatGPT Work for more complex tasks.

In this guide, we'll cover:

• What happened to ChatGPT Atlas and what replaced it
• What the ChatGPT Chrome extension can do
• How to install the extension and use ChatGPT Work
• How to connect meeting transcripts to ChatGPT with Tactiq

If you're looking for meeting-related AI workflows, Tactiq lets you bring meeting transcripts into ChatGPT through its MCP connector. We'll cover how to set this up later.

What Happened to ChatGPT Atlas?

OpenAI launched ChatGPT Atlas in October 2025 as an AI-powered web browser with ChatGPT built directly into the browsing experience.

It included a ChatGPT sidebar for asking questions about webpages and an AI agent mode for completing multi-step tasks.

Since its retirement, Atlas no longer receives updates, including security updates. OpenAI has shifted its browser-based AI capabilities into ChatGPT and Codex.

For users who relied on Atlas's agent mode, OpenAI now recommends ChatGPT's desktop app and its Work capabilities.

💡 Pro tip: ChatGPT's browser tools can help you work with webpages, but they don't transcribe live meetings. Tactiq's Chrome extension transcribes Google Meet, Zoom, and Microsoft Teams calls in your existing browser. You can then access those meeting transcripts in ChatGPT through Tactiq's MCP connector.

What happened to your Atlas data?

According to OpenAI's official retirement guide, here's what happened to your browser data:

• Bookmarks: These didn't transfer automatically. You can import previously exported HTML files into Google Chrome.
• Open tabs: Atlas tabs didn't transfer. You can reopen pages if you previously saved their URLs or bookmarks.
• Browsing history: Atlas browsing history didn't transfer automatically.
• ChatGPT conversations: Your chats remain available in ChatGPT, subject to your account and workspace settings.

If you didn't export your data before Atlas retired, contact OpenAI Support for assistance.

The ChatGPT Chrome Extension That Replaced Atlas

OpenAI now offers the ChatGPT browser extension, previously called the Codex Chrome extension.

Unlike ChatGPT Atlas, the extension works with your existing Google Chrome profile, so you don't need to switch to a new browser. You can keep your open tabs, signed-in accounts, and installed Chrome extensions.

If you're exploring other ways to use ChatGPT while browsing, see our guide to the best Chrome extensions for ChatGPT.

What the ChatGPT Chrome extension can do

The extension lets ChatGPT work with webpages you're already viewing, so you don't have to copy information between tabs. If you're also comparing password management options, check out NordPass vs LastPass to see which Chrome extension offers the security features and convenience that best fit your browsing needs.

Depending on your setup, you can:

• Use side chat: Ask ChatGPT questions while keeping your current webpage visible.
• Mention tabs: Reference an open browser tab in ChatGPT to provide context for your question.
• Work with selected text: Highlight content on a webpage and ask ChatGPT to explain or summarize it.
• Ask questions about YouTube videos: Use available video context to research or understand content.
• Interact with websites: Let ChatGPT navigate pages and complete supported actions within your signed-in sessions, subject to permissions.

For example, you could ask ChatGPT to review information across several tabs before preparing a research summary.

Chrome extension vs. the built-in browser

ChatGPT also has a built-in browser in its desktop app for Mac and Windows. Both options support browser-based tasks, but they use different browsing environments. Available features may depend on your plan and workspace settings.

ChatGPT Chrome extension:

• Uses your existing Chrome profile.
• Can access your open Chrome tabs and signed-in sessions, subject to permissions.
• Works alongside your installed Chrome extensions.
• Useful for tasks involving websites you're already using.

Built-in browser:

• Uses its own browser state, separate from your Chrome profile.
• Keeps browsing within the ChatGPT desktop app.
• Supports its own browser extensions.
• Useful for research and tasks within the desktop app.

For example, the Chrome extension makes sense when you need ChatGPT to work with a CRM you're already signed into. The built-in browser is useful when you want to review several webpages without leaving ChatGPT.

How to Set Up the ChatGPT Chrome Extension

You can install the ChatGPT browser extension directly in Google Chrome to access ChatGPT alongside your webpages.

If you also want ChatGPT Work to control your browser for multi-step tasks, connect it through the desktop app.

Install the ChatGPT extension in Google Chrome

1. Open the official ChatGPT extension in the Chrome Web Store.
2. Click Add to Chrome and review the requested permissions.
3. Confirm the installation, then open a webpage you want to work with.
4. Click the Extensions icon in your Chrome toolbar and select ChatGPT.
5. Use the side chat to ask questions about the page or give ChatGPT a task.

For example, you could open a competitor's website and ask ChatGPT to summarize its pricing information.

You can also highlight text or mention other open tabs when you need more specific context.

Connect Chrome to ChatGPT Work

For more advanced agentic browsing, you can connect the same extension to ChatGPT Work. This allows ChatGPT to interact with websites using your existing signed-in sessions.

Here's how:

1. Open the ChatGPT desktop app on Mac or Windows.

2. Go to Settings → Computer Use.

3. Find Google Chrome in the browser list.

4. If Chrome displays Install, follow the extension setup prompt. If you've already installed it, check its connection.

5. Return to Computer Use and confirm that Chrome displays Manage.

6. Start a ChatGPT Work chat, type @, and select Chrome from the browser options.

You can now ask ChatGPT to complete supported tasks using websites where you're already signed in. OpenAI requests permission before accessing new websites unless you've previously approved them.

The extension also supports Microsoft Edge, Brave, Vivaldi, and Opera. However, Opera doesn't support side chat. You can still use it for browser control and tab mentions through the desktop app.

ChatGPT Work: The ChatGPT Atlas Alternative for Agent Workflows

ChatGPT Atlas introduced agent mode to help users complete multi-step tasks while browsing. Now, OpenAI directs those workflows to ChatGPT Work.

However, ChatGPT Work goes beyond Atlas's browser-based agent mode. Instead of focusing on tasks within a browser, Work can combine information from files, connected apps, and websites to complete more complex workflows.

For example, you can use Work to:

• Research competitors across multiple websites and prepare a comparison report.
• Gather project updates from connected apps and create a presentation.
• Organize information into spreadsheets or documents.
• Update records in web applications using your connected browser.

ChatGPT Work is available alongside Chat and Codex in the ChatGPT desktop app. Chat handles everyday conversations, while Codex focuses on coding tasks.

How ChatGPT Work uses your Chrome browser

Once you've connected the extension, ChatGPT Work can interact with websites through your existing Chrome sessions.

For example, imagine you're researching competitors before updating your pricing strategy.

1. Open ChatGPT Work and select Chrome using @.
2. Ask ChatGPT to review pricing pages across several competitors.
3. Have it organize the findings into a comparison report.

Review the report's pricing details and source links before using the findings to inform your strategy.

Tactiq + ChatGPT: Bring Your Meeting Transcripts Into ChatGPT With the Tactiq MCP

Finding a decision from last week's meeting shouldn't require searching through transcripts manually. Tactiq captures meeting transcripts and generates AI summaries, while its MCP connector lets ChatGPT retrieve that information directly.

Capture meetings with the Tactiq Chrome extension

The Tactiq Chrome extension transcribes Google Meet, Zoom, and Microsoft Teams calls without a bot joining.

You can also use:

• Ask Tactiq AI to ask questions during meetings.
• Custom AI Prompts to generate summaries, action items, and follow-ups.
• AI Workflows to automate recurring post-meeting tasks.

Connect Tactiq to ChatGPT

Tactiq is available directly in ChatGPT's Plugin directory, so you don't need to configure MCP manually.

1. Open Plugins in the ChatGPT sidebar and search for Tactiq.
2. Click Install plugin, sign in, and select Allow.
3. Start a new chat, open the + menu, and select Tactiq.

Your Tactiq plan determines what ChatGPT can access:

• Free and Pro: Search and list meetings.
• Team or higher: Access meeting details, AI summaries, and full transcripts, subject to your permissions.

With a Tactiq Team plan or higher, you can ask ChatGPT to retrieve a recent customer meeting, summarize key decisions, and identify follow-up tasks. You can then use those details to prepare customer updates or project reports.

See Tactiq's full ChatGPT MCP guide for details.

Using ChatGPT After Atlas

ChatGPT's browser extension and Work capabilities offer different ways to continue browsing with AI after Atlas.

The extension works with your existing Chrome sessions, while Work supports more complex workflows across websites and connected apps.

If your tasks involve meeting information,Tactiq can bring that context into ChatGPT without manually copying transcripts.
