Research Lit

This one searches and analyzes academic papers across a surprising number of sources. It'll check your local PDFs, Zotero library, Obsidian notes, then hit arXiv, Semantic Scholar, and even newer APIs like DeepXiv and OpenAlex if you ask for them. The source prioritization is smart: it starts with what you already have before going to the web. You can override which sources it checks with a simple flag, and it'll optionally download arXiv PDFs for you. Most useful when you're starting a literature review or need to quickly understand what a paper says without reading 40 pages. The Zotero integration is especially nice since it pulls your existing highlights and annotations.
