About Context Peek
Context Peek is a browser extension that provides instant AI-powered link previews when hovering over hyperlinks. It scrapes the content of the linked page in the background and sends it to a backend API, which returns a concise summary, estimated read time, and credibility score.
Built for researchers, journalists, and information seekers, Context Peek adds context without leaving the page, helping you decide if a link is worth clicking.
