Bluf is an AI-powered web page assistance tool that provides concise answers, summaries, and explanations of web pages. It is currently available on Chrome and Firefox browsers. Bluf counts a prompt as a message sent to summarize or explain a request, and multiple questions within a single message count as one prompt. Bluf collects usage data and content prompt answers, but only retains data for up to 30 days. For support or inquiries, users can contact Bluf via email.
