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) ## Scribbr Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits. Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit. The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow. **Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review. - **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter. - **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission. - **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural. - **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search. - **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document. **Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours **Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order [Profile (Markdown)](https://openaitools.app/tool/scribbr.md) ## Frequently Asked Questions ### How do BLUF and Scribbr compare in monthly traffic?
