How long of an article can I summarize at once?

The maximum depends on the AI model's context window. GPT-4o handles up to ~128K tokens (roughly 300 pages). Claude 3.5 Sonnet handles ~200K tokens. For practical purposes, any single article or document you encounter on the web can be summarized in one prompt. Extremely long documents (full books) may need to be summarized in sections.

How accurate are AI summaries?

Modern AI models (GPT-4o, Claude 3.5 Sonnet) produce highly accurate summaries of factual content. They reliably capture main arguments, key data points, and conclusions. However, always verify critical details — especially numbers, dates, and technical claims — against the original text if accuracy matters for your use case.

Can I summarize PDFs and documents, not just web articles?

If the PDF is viewable in Chrome (Chrome has a built-in PDF viewer), you can select text from it and summarize with Prompt Anything Pro. For Google Docs, Notion pages, and other web-based document editors, the extension works as long as you can select text on the page.

How much does each summary cost?

Summarizing a 2,000-word article with GPT-4o costs approximately $0.01-0.02. A shorter article (500 words) costs less than a penny. Even summarizing 50 articles per day would cost under $1/day. The exact cost depends on the input length, model chosen, and summary length requested.

Before You Start

Google Chrome browser (desktop)
Prompt Anything Pro installed from the Chrome Web Store
An API key from OpenAI, Anthropic, or Google configured in the extension

Install Prompt Anything Pro and configure your API key

If you have not already, install Prompt Anything Pro from the Chrome Web Store and add your API key in Settings. See our BYOK setup guide for detailed instructions. Once configured, you are ready to summarize any content on the web.

Navigate to the article you want to summarize

Open the article, blog post, research paper, documentation page, or any long-form content you want to summarize. This works on any website — news sites, Medium articles, academic papers, technical documentation, legal documents, email newsletters, and more. If you can see the text in your browser, you can summarize it.

Select the text you want to summarize

Click and drag to highlight the text you want to summarize. You can select a few paragraphs, an entire section, or use Ctrl+A (Cmd+A on Mac) to select all visible text on the page. For best results, select the article body text and exclude navigation menus, sidebars, and footer content. The more focused your selection, the more relevant the summary will be.

Pro Tip

For very long articles (5,000+ words), summarize in sections rather than all at once. Select the introduction and first half, summarize it, then do the second half. This gives you more detailed summaries than trying to compress the entire article into one summary.

Click the floating button and choose the "Summarize" template

Click the floating PlugMonkey button that appears near your selection. The prompt modal opens with your selected text pre-loaded. Choose the "Summarize" template from the template categories. This template is optimized to extract key points, main arguments, and conclusions from long-form text. You can also choose "Summarize as Bullet Points" for a structured list format or "ELI5" for a simplified explanation.

Review the AI summary and take action

Click "Send" and the AI generates your summary in seconds. The response appears in the modal with key points, main arguments, and a conclusion. From here you can: Copy to clipboard to paste into your notes, Save to library for future reference with automatic tagging, or Send a follow-up prompt asking for more detail on a specific point from the summary. The summary is stored in your local response library, searchable and exportable.

Try different summarization approaches

Beyond the basic Summarize template, experiment with other approaches for different needs. Use "Extract Key Facts" for data-heavy articles to pull out statistics, dates, and named entities. Use "Explain Like I Am 5" for technical papers you want simplified. Use "Translate + Summarize" to summarize a foreign-language article into English key points. Write a custom prompt like "List the 3 most actionable insights from this article" for targeted extraction.

Pro Tip

Create a custom template for your most common summarization need. If you read research papers regularly, create a template that extracts methodology, findings, limitations, and practical implications in a structured format.

Summary

You can now summarize any article, document, or long-form content in seconds without leaving the page you are reading. Prompt Anything Pro's Summarize template extracts key points, main arguments, and conclusions with one click. The BYOK approach means each summary costs a fraction of a cent through direct API pricing. Build a habit of summarizing articles before deciding whether to read them fully — the AI summary tells you in 15 seconds whether the article is worth 15 minutes of your time. Save summaries to your local library for building a personal knowledge base that is searchable and exportable.
