The Topic Linking plugin streamlines research workflows by organizing and linking content from PDFs, web bookmarks, and other notes within Obsidian. It allows users to convert PDFs into searchable Markdown files, extract web link content, and generate topic-based connections between related files. The plugin leverages topic modeling to identify key themes across multiple documents, creating linked topic notes and an index to track and explore relationships between research materials. Users can generate a bibliography of sources and extract metadata from files, while features like file chunking, page annotations, and Zotero integration support large collections. This makes it a powerful tool for researchers managing large repositories of academic literature, web content, and personal notes.
