BLUF

BLUF is a browser extension for extracting key points and asking questions about material being read. Its website describes support for web pages, PDFs, YouTube videos and local files, with separate summarize and explain actions. A summary can help decide which part of a document deserves attention; an explanation can restate a difficult passage. Neither replaces checking the original source for qualifications, numbers or supporting evidence. The provider recommends the dedicated summarize and explain controls for long material rather than treating an ordinary chat request as equivalent. Plans combine a monthly prompt allowance with a separate maximum number of words per page or document. A paid prompt allowance therefore does not remove the per-document limit. For longer material, the FAQ suggests selecting a smaller passage. It also states that a request which fails to complete is not counted as a prompt, correcting the contrary statement in the earlier directory copy. The site links to official Chrome and Firefox listings; the Chrome listing was inspected, while installation and browser compatibility were not tested. The main page names additional browsers that its FAQ does not consistently confirm. Verify the relevant store and current compatibility before choosing a platform. The provider says prompt content is sent to an external model service for processing. Review the extension permissions and current privacy terms before using private documents. This review did not install the extension, submit a document or assess answer accuracy.
