SourceShelf: PDF to Markdown

Turn PDFs, scans, and webpages into clean local Markdown — then ask questions across the research you choose. SourceShelf is a private research library for iPhone and iPad. Capture useful webpages from Safari, import PDFs, images, RTF, Markdown, and text, organize sources into reusable Packs, search locally, and keep saved research available offline. ASK THIS PACK Ask questions about a saved Pack directly inside SourceShelf. On supported Apple Intelligence devices, Ask This Pack uses Apple’s on-device foundation model with the sources you selected as context. PDF & IMAGE TO MARKDOWN Import text-based PDFs directly or use on-device OCR for scanned PDFs and images. Recognized text becomes searchable and can be read, organized, exported, or used with Ask This Pack. SAVE WEB RESEARCH Use the Safari extension to capture useful webpages as local Markdown. Bring web research into the same library as your documents, then combine related sources in a focused Pack. ORGANIZE, SEARCH & READ OFFLINE Build Packs for projects, courses, trips, topics, or long-term research. Star important sources, search titles and content, and read saved material even when you're offline. PORTABLE BY DESIGN Move complete Packs with Files, AirDrop, or the share sheet. SourceShelf supports portable Markdown-based formats including AI Reference Packs, OKF bundles, and llms.txt packages. PRIVATE BY DEFAULT No SourceShelf account. No analytics or tracking. No SourceShelf cloud. Your research stays local unless you choose to export or share it. One purchase includes SourceShelf for iPhone, iPad, and Mac. No subscription.
