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) ## SpecsPlain SpecsPlain is a small, focused browser extension built for developers who spend time inside specification documents. Standards like the ECMAScript (TC39) spec describe behavior through terse, formally worded algorithms that are precise but hard to read quickly. SpecsPlain inserts an Explain control directly into the specification page; clicking it sends the surrounding algorithm to Google's PaLM AI, which returns a plain-language walkthrough of the steps. The extension is deliberately narrow in scope. At version 1.0.0 it targets the ECMAScript spec, and its stated goal is to make formal algorithm definitions easier to follow without leaving the page you are already reading. It is published by individual developer He-manth (h3manth.com) and installs as a standard Chrome extension that requires permission to read website content so it can process the spec text on screen. SpecsPlain is free with no account or paid tier advertised. It is best treated as a convenience layer for spec reading rather than a full documentation platform: it does not host docs, track changes, or manage projects. Its listed Chrome Web Store privacy disclosure notes that it handles website content, and the developer declares that data is not sold to third parties or used for unrelated purposes. **Pricing & Plans:** SpecsPlain is free. It is distributed as a no-cost Chrome extension with no advertised subscription or paid plan. - **In-page Explain button:** Adds an Explain control to the specification document so you can request an explanation without switching tabs or tools. - **PaLM AI powered explanations:** Uses Google's PaLM AI to convert formal spec algorithms into readable, step-by-step descriptions. - **ECMAScript (TC39) focused:** Tuned for the ECMAScript specification, turning dense algorithmic text into something a developer can follow quickly. - **Human-readable algorithm output:** Generates an explanation of what each step in an algorithm does, rather than restating the formal notation. - **Minimal, lightweight install:** A small extension with a simple one-click workflow and no account setup required. **Strengths:** Completely free with no sign-up required; Works directly inside the spec page you are already reading; Turns dense algorithmic notation into readable explanations; Very small, lightweight extension **Limitations:** Limited to the ECMAScript (TC39) specification at version 1.0.0; Depends on Google's PaLM AI, so quality varies with the model output; No ratings yet and a very small user base, so community feedback is minimal [Profile (Markdown)](https://openaitools.app/tool/specsplain.md) ## Frequently Asked Questions ### How do BLUF and SpecsPlain compare in monthly traffic?
