BLUF
FreemiumBrowser extension that summarizes and explains pages, PDFs and videos
What is BLUF?
BLUF, short for Bottom Line Up Front, is a browser extension that summarizes websites, PDF files and YouTube videos and lets you ask follow-up questions. It is meant for readers who want the key points of long content quickly.
Three modes cover most needs: Summarize pulls out the main highlights, Explain turns dense or technical passages into plain language, and Ask answers specific questions about the content. It also works with local files.
The panel opens with the Shift + Alt + B keyboard shortcut, so you can call it up on any page without leaving it. Answers stay tied to the content you are viewing, which makes it handy for long reports, research papers and lecture videos.
