How to use ChatGPT summaries as context in Claude, Gemini and other chats
Pasting a whole web page into an AI chat rarely works well. Menus, cookie notices, comments and related-article lists come along with the text, and long pastes can crowd out the question you actually wanted to ask. A short summary of the page makes much better context: a few hundred words that carry the facts, which you can hand to any assistant before you ask it anything.
This guide shows a simple routine for that, using the free ChatGPT summary Chrome extension to produce the summary and any chat you like to work with it.
The routine in four steps
- Summarize the page where you read it. Press Ctrl+Shift+E on the article. The main points open in a panel next to the text. (How the panel works is covered on the ChatGPT Summary home page.)
- Copy it with the source. Use the copy button, then add the page link and the date on top. The assistant can't check the page later, but you can.
- Paste it into the chat you're using for the task, whether that's Claude, Gemini or another ChatGPT conversation, with a line saying what it is: "Summary of an article I'm reading, for context."
- Ask the real question in the same message or the next one.
Follow-up prompts that work with a summary
| You want | Paste the summary, then ask |
|---|---|
| A second opinion | Which of these claims would you check first, and why? |
| To compare sources | Here are summaries of two articles on the same topic. Where do they disagree? |
| Something to send | Turn this into three sentences for a colleague who hasn't read it. |
| To learn | Ask me five questions that test whether I understood this. |
| A decision | Given this, what would I need to know before acting on it? |
Shape the summary for the next chat
The extension uses one prompt for every page, and you can change it in its settings. If you mostly summarize to give context to another assistant, a prompt written for that job helps. A few we'd try:
- "List the main claims of the article, each with the evidence it gives."
- "Summarize the article in five bullet points, then list every number and date it mentions."
- "Summarize the article neutrally, without opinions, in under 150 words."
Keeping numbers and dates in the summary matters more than it seems: they're the details an assistant is most likely to get wrong if it has to guess.
Videos work the same way
A long lecture or podcast benefits even more, because transcripts are long and repetitive. Summarize the video with the YouTube video summarizer, then paste that summary into a chat and ask your follow-up questions there.
When to give the chat more than a summary
A summary drops layout, images and anything visual. If your question is about how a page looks (a landing page, a pricing table, a design) give the assistant the page itself. A full page capture saved as an image or PDF can go straight into Claude, Gemini or ChatGPT as a file.
Common questions
Why not paste the whole article into the chat?
You can, but you also paste navigation, ads and comments, and very long pastes can push your instructions out of focus. A summary keeps the useful part and leaves room for the conversation.
Can I use the summaries with Claude or Gemini?
Yes. The summary is written by ChatGPT, but it's plain text, so you can paste it into any chat.
Does the extension keep the summaries?
No. It sends the page text to ChatGPT or the OpenAI API when you ask for a summary and doesn't store it. Copy anything you want to keep. See the privacy policy.
Summarize where you read, then ask anywhere.
