The extension applies that idea to everyday reading: instead of wading through a long article, a dense report or a 40-minute video, you open the toolbar or press Shift+Alt+B and get the key points in seconds. The tool offers two main modes. Summarize condenses any page or document into its main ideas, while Explain rewrites complex material — technical jargon, academic papers, legal language — into something a general reader can follow. After either action you can ask follow-up questions to dig into specific details, and the answers stay grounded in the page you are viewing. BLUF works across Chrome, Firefox, Edge and Opera, and handles websites, PDFs, YouTube videos and local files within the same interface. A free tier provides 25 prompts per month, while paid plans raise the prompt allowance and the maximum words per page, making it practical for students, researchers, journalists and busy professionals who read more than they can comfortably digest. **Pricing & Plans:** Freemium. Free plan gives 25 prompts/month and up to 20,000 words per page; Standard is $4/month with 200 prompts and 50,000 words/page; Professional is $10/month with unlimited prompts and 200,000 words/page. - **One-click summarize:** Extract the main points of any web page, PDF or YouTube video without reading or watching the whole thing. - **Plain-language explain:** Turn dense technical, academic or legal content into a simple explanation that is easy to digest. - **Follow-up questions:** Ask the assistant about specific points in the content to pull out exactly the detail you need. - **Works on many content types:** Handles websites, PDF documents, YouTube videos and local files from a single interface. - **Keyboard shortcut access:** Press Shift+Alt+B or right-click selected text to invoke BLUF instantly while you browse. **Strengths:** Runs inside the browser, so you never leave the page you are reading; Supports PDFs, YouTube videos and local files, not just websites; Genuinely useful Explain mode for difficult technical material; Clear free tier and inexpensive paid plans **Limitations:** Prompt-based questions are not optimized for very large pages — the dedicated buttons work better; Prompt and answer content is sent to OpenAI for processing, which may concern privacy-sensitive users; Summarize and Explain are the main actions; deeper configurability is limited [Profile (Markdown)](https://openaitools.app/tool/bluf.md) ## Casper AI Casper AI is a browser extension aimed at people who spend their day absorbing information: analysts, strategists, policy watchers and business developers. Once installed in Chrome, it works on the page or PDF you are already looking at, using AI models to condense long articles, reports and papers into short summaries you can actually finish. The stated goal is to remove the reading bottleneck before a meeting, an exam or an investment decision. The extension goes a step beyond plain summarization. It is designed to help you highlight the most important new insights, pull structure out of dense documents and turn what you learned into short notes you can share with teammates and stakeholders. Because it lives in the toolbar, the workflow is: open the source, summarize, and send the takeaway, without moving content into a separate tool. Casper AI is distributed through the Chrome Web Store by its developer and offers in-app purchases on top of its free tier. It has a sizeable user base and a strong average rating, and it explicitly targets non-technical users who want AI assistance without building a prompt workflow themselves. Expect it to save time on reading-heavy tasks rather than to replace expert judgement on the documents themselves. **Pricing & Plans:** Casper AI is listed as freemium in the Chrome Web Store with in-app purchases available alongside the free extension. - **Web page summarization:** Condense long articles and pages into short summaries directly from the browser, without copying text into another app. - **PDF summarization:** Work through reports and papers in PDF form and pull out the central points rather than reading cover to cover. - **Insight highlighting:** Surfaces the most important new information in a document so you can focus attention where it matters. - **Shareable notes:** Turn what you have read into concise notes you can forward to colleagues and stakeholders. - **Chrome toolbar workflow:** Runs as a lightweight extension inside Chrome, so summarizing is one action away on any page you visit. **Strengths:** Summarizes both web pages and PDFs from the same browser extension; 10,000+ users and a strong average rating in the Chrome Web Store; Designed for non-technical professionals, with no prompt engineering required; Share-oriented output makes it easy to brief teammates **Limitations:** Requires Chrome, since it is delivered only as a browser extension; Summaries are only as good as the source document, so critical review still matters; Some capability sits behind in-app purchases rather than the free tier [Profile (Markdown)](https://openaitools.app/tool/casper-ai.md) ## Frequently Asked Questions ### How do BLUF and Casper AI compare in monthly traffic?
