The Quadro plugin brings qualitative data analysis (QDA) capabilities to Obsidian, offering an open-source alternative to proprietary software like MAXQDA and Atlas.ti. It allows researchers to store and analyze qualitative data in Markdown format, making it accessible, future-proof, and compatible with other tools. Quadro supports coding (assigning tags to text) and extraction (transforming text into structured data), using bidirectional links between Data and Code files. This plugin also integrates seamlessly with Obsidian's features, such as Graph View and Outgoing Links, and can be extended using other plugins. With a focus on flexibility and customizability, Quadro provides an adaptable solution for qualitative research workflows.

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.

The Entity Linker plugin enhances research workflows in Obsidian by linking terms or note titles to corresponding standard entities from databases like Wikidata, Wikipedia, and OpenAlex. Users can link selected text or active note titles to entities via OpenAlex API, creating dedicated entity notes. This plugin simplifies referencing scholarly works and organizing knowledge. It also supports additional functionality like adding email for faster API access and integrates seamlessly with other plugins like Wikidata Importer and Wikipedia. The tool is ideal for researchers and academics looking to streamline entity management in their notes.

The You and Your Research plugin consolidates tools for research and information retrieval into an integrated interface within Obsidian. It allows users to streamline tasks such as extracting web content and generating research notes using OpenAI models. The plugin supports inputting URLs for content extraction, linking local files for deeper research, and saving notes directly into your vault. Users can customize settings, including OpenAI API keys, preferred file locations, and tag management. By centralizing research tasks, it reduces the need for context switching and enhances focus. This plugin is ideal for knowledge workers and individuals conducting intensive research or planning activities.

The Scholar plugin is a game-changer for researchers and academics who want to streamline their library management, enhance paper reading, and easily retrieve papers from their local library. With this plugin, you can add papers from external links with just a few clicks, quickly search and retrieve papers, and even check the details of referred papers without leaving the tool. Additionally, you can copy paper BibTex entries for easy citation management. The plugin also offers advanced features such as automatic PDF downloading and paper metadata creation, making it an essential tool for anyone who needs to manage large collections of research papers.
