Instead of generating a summary somewhere else, it works directly on the page: click the highlighter icon in the address bar and the extension paints the most important sentences of the article in a highlight colour, giving you an instant visual tl;dr. Under the hood it uses extraction-based summarization — sentences are scored by how frequently their terms appear across the whole article. That keeps it fast, entirely client-side and easy to understand, but also means it highlights important-sounding sentences rather than producing polished abstractive prose. The amount of highlighting is adjusted by clicking the icon repeatedly, and the icon itself shows less "ink" as coverage grows. The extension is open source, with code hosted on GitHub, and its privacy policy states that it does not collect user data or transmit anything remotely. It is rated around 3.6 stars from roughly 25 reviews with about 20,000 users, and the last update (v3.6.0) landed in March 2024. It is best suited to standard HTML articles — news, blogs, long-form posts — rather than PDFs or scanned documents. **Pricing & Plans:** Free. Auto Highlight has no paid plans, no subscription and no in-app purchases — it is distributed at no cost through the Chrome Web Store. - **One-click page highlighting:** Click the highlighter icon in the address bar and the extension immediately marks the sentences that carry the article's core meaning. - **Adjustable coverage on repeat clicks:** Each additional click increases or reduces how much of the article gets highlighted, so you can dial coverage up or down to taste. - **Term-frequency sentence ranking:** Important sentences are ranked from term frequencies across the full article, a lightweight extraction-based summarization technique. - **Visual ink-level indicator:** The toolbar icon visually shows "ink" running out as more highlighting is applied, giving instant feedback on current coverage. - **Open source and privacy-first:** The source code is published on GitHub, the privacy policy states no data is collected or transmitted, and options stay local. **Strengths:** Free and open source with code you can inspect; Instant tl;dr directly on the page — no copy-pasting into another tool; No account, no sign-up and no data collection; Adjustable highlight coverage via repeated icon clicks **Limitations:** Term-frequency approach can highlight obvious or repeating sentences instead of the truly key points; Coverage is adjusted by clicking the icon repeatedly rather than by fine-grained controls; Last updated March 2024 and only rated 3.6, reflecting some inconsistent page results; No native support for PDFs or images — it is built for HTML article text [Profile (Markdown)](https://openaitools.app/tool/auto-highlight.md) ## BLUF BLUF takes its name from the military communication principle "Bottom Line Up Front" — lead with the conclusion. 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) ## Frequently Asked Questions ### How do Auto Highlight and BLUF compare in monthly traffic?
