What is Locus?

Locus is a browser extension that helps you find, organise, and reference information across web pages, long documents, PDFs, and videos. Instead of scrolling through lengthy content or rewatching videos to locate specific details, you can search and jump directly to relevant sections. The tool works as a Chrome extension, making it available wherever you browse. It's designed for researchers, students, professionals, and anyone who regularly works with large amounts of online content and needs faster ways to locate and cite specific information.
