ScholarThread

ScholarThread keeps your reference library, PDF reading, and notes in one place, on iPhone, iPad, and the web. Import PDFs, DOIs, or BibTeX files, save papers from any app via the share sheet, search OpenAlex, or connect Zotero to bring in existing collections. Read PDFs and EPUBs in-app with five-colour highlights, notes on highlights, and Apple Pencil annotation on iPad. Papers stay readable offline, with highlights and notes syncing when you reconnect. Write literature and concept notes from templates, link them with [[wikilinks]] and typed links such as Supports and Refutes, and explore connections in a knowledge graph. Search papers and notes from one box, or ask questions about your library and see which papers each answer used. Notes export as Markdown or an Obsidian-compatible folder, or sync with your own Git repository. Start without an account; sign in for cross-device sync, Zotero, and AI features.
