Frequently asked questions about BLUF

What is BLUF?

BLUF is an AI-powered browser extension that provides concise summaries and explanations of content from websites, PDFs, YouTube videos, and local files. It helps users quickly grasp key points without reading lengthy material.

Which browsers support BLUF?

BLUF is currently available on Chrome and Firefox. Support for other browsers is planned for future releases.

What counts as a prompt in BLUF?

A prompt is any message sent to BLUF, including text-based questions or requests to summarize or explain content. Multiple questions within one message count as a single prompt.

What does 'words/page' mean in BLUF's pricing?

'Words/page' refers to the maximum number of words that can be processed in a single page or document. If a page exceeds this limit, users can select a portion of the page to focus on.

Can I ask BLUF to summarize or explain a page using the prompt system instead of the dedicated buttons?

While possible, it is not recommended for large pages. The dedicated summarize and explain buttons are optimized for processing large content, whereas the prompt system may not handle it as effectively.

Does BLUF collect user data?

BLUF collects usage data but not the content of prompts or answers. It sends prompt content to OpenAI for processing, which retains data for no longer than 30 days as per their policy.
