Cruxly — AI Summarizer for Video, PDF & More by Alex Bezrukov

Cruxly turns YouTube videos and PDF documents into structured summaries you can chat with. It's
Paste a link or open a PDF, and Cruxly reads the whole thing so you don't have to. You get a clear breakdown of the key points in minutes. Then ask the built-in AI chat follow-up questions: it remembers the full content, so answers come from what's actually there instead of generic guesses.

On a PDF, use the banner that appears on the page, or right-click any PDF link and choose Analyze PDF with Cruxly.
Results and chat open in the browser's side panel, so you never leave the tab.
