How to use the ChatGPT Chrome extension

You have three software pricing pages open, a product walkthrough waiting on YouTube, and a decision to make before your next meeting. The useful question for AI is specific: which option fits your needs, and what evidence supports that choice?

OpenAI’s ChatGPT browser extension lets the desktop app use your existing Chrome tabs and browser profile. Bring a pricing page into the conversation, then ask what its terms mean for your team. The practical payoff is less time assembling context before you can ask a useful question.

Start with one page and a question whose answer you can check. Once that works, move on to comparing sources and preparing a draft. The exercises below give you a straightforward way to try each.

Set up Chrome and ChatGPT

Use desktop Chrome and the current ChatGPT desktop app. Install the app, sign in, and choose ChatGPT, then Work, for the desktop tasks in this guide. Codex also supports browser tasks. Browser availability can depend on rollout and workspace settings.

1. In the ChatGPT desktop app, open Settings > Computer Use.
2. Select Chrome and follow any prompt to install the required plugin.
3. Click Install beside Chrome. Install the extension from the store page that opens and review its permissions.
4. Return to Computer Use. Chrome should show Manage. Use the Chrome profile where you installed the extension.

Follow the official setup guide if a step looks different. To open side chat, select ChatGPT from Chrome’s toolbar or Extensions menu. On a Mac, the shortcut is Cmd + Shift + .

Work and Codex share usage, with models and limits varying by plan. Check OpenAI’s current plans and usage guide before assuming a long browser task is unlimited.

Turn an article into a useful conversation

Open an article you would otherwise read for work. Right-click the page and choose Ask ChatGPT. You can also bring highlighted text into side chat when a particular passage needs explaining. These shortcuts are covered in OpenAI’s browser feature updates.

Begin with a request that separates the author’s argument from the evidence behind it:

Using this page, explain the main argument in 150 words. List the evidence the author gives and identify two claims that would need independent verification. Include the article’s title and URL so I can check the source.

Then ask the question that brought you to the article. For a business story, that might be: “What would this change for a small company buying this technology?” For a research paper: “Which findings come from the experiment, and which are the authors’ interpretation?”

Check a couple of the answer’s concrete claims against the page. If a date, figure or qualification has disappeared, ask for a correction. A useful summary should preserve the details that affect your decision.

Be explicit when you want outside research. “Use only this page” keeps the task focused on reading; “check this claim against independent sources and link them” asks for a separate verification step. OpenAI’s prompting guide explains how to specify sources, output and boundaries.

Compare open tabs against your actual needs

Now open two or three pages that address the same decision. Software plans, conference agendas and course descriptions all work well. Use tab mentions to identify the pages you want ChatGPT to consider; the extension supports open-tab context in side chat.

For a software comparison, try this after adding the relevant tabs:

Compare these three pricing pages for a team of five. Make a table with monthly billing, annual commitment, minimum seats, usage limits and export options. Include a source URL for each product. Mark anything the pages do not disclose as “not stated.” Calculate the total for five users only when the pricing terms support it.

That last instruction matters. A neat comparison can conceal incompatible units: a price per user, a price per workspace and a price available only with annual payment. Ask ChatGPT to show the basis of each calculation before you use the totals.

Follow up with your constraint: “We need monthly billing and CSV export. Which plans explicitly meet both requirements, and what still needs checking?” This gives the comparison a purpose and exposes the missing information you may need to ask a vendor about.

When starting from the desktop app, select @Chrome to target Chrome. @Browser targets ChatGPT’s separate built-in browser, which has its own profile. OpenAI’s browser guide explains that distinction. Choosing the right one helps keep the task connected to the tabs you meant to use.

Find the useful parts of a YouTube video

Open a YouTube video and use side chat. When captions are available, ChatGPT can work from its timestamped transcript.

Use the available transcript to identify the five most useful ideas in this video. Give a timestamp for each and explain who would benefit from it. Then turn the practical advice into a short checklist. Say if you cannot access the transcript.

For a tutorial, ask a more specific question: “Where does the speaker explain how to export the finished file?” For an interview, try: “Which claims are backed by examples, and where does the speaker make a prediction?”

Use the timestamps to return to the video and check the relevant section. A transcript can miss an onscreen demonstration, and captions can mishear names or numbers. If the key information is visual, review that section yourself or supply a screenshot with your question.

Use a page to prepare a better draft

A useful next exercise is preparing a response while the source material is still open. Take a conference agenda, for example, and ask for an email explaining which sessions you want to attend:

Using this agenda, draft a 120-word email to my manager proposing the two sessions most relevant to customer retention. Explain what I hope to learn, include the session times, and flag any scheduling conflict. Put the draft in this chat for me to review.

The same approach works for a response to a customer’s question or an internal update about a product announcement. Supply the audience, purpose and facts that must remain accurate. Review names, commitments and dates before using the draft.

Browser tasks can also involve actions inside sites where you are signed in. OpenAI’s Computer Use guidance explains that website actions may be treated as coming from your account. If you want ChatGPT to fill a form or prepare an email in the site itself, specify where it should stop: “Fill the draft and let me review it before submitting.”

Keep access and evidence under control

Review each website permission request; start with Allow once. In Computer Use, select Manage beside Chrome to review allowed or blocked sites. Read the extension’s data guidance before using confidential material.

Choose a public page for your first exercise. For work material, use an account and workspace approved for that information. Treat webpage instructions as source material to evaluate; an instruction embedded in a page is not a reason to send files or change settings.

If the connection fails, follow the extension troubleshooting checklist. If the connection works but the answer is wrong, first ask which page or passage ChatGPT actually used. Then narrow the question and check the result against the source.

For your first session, choose one article you need to understand today. Ask for its argument, check the evidence, and request a short note explaining what it means for your work. That gives you a finished result you can judge before handing over a larger task.
