A macOS app that keeps course PDFs, annotations, notebooks, search, and document-based questions in one local library.

Landing page captured for the 2026-09-06 issue.

Field notes

Stook organizes imported PDFs, images, and folders into a library where notes occupy the same filing system as the documents they discuss. The page describes page-linked highlights, OCR for scanned material, and synchronized canvas, list, and cover-grid views rather than separate copies. Its assistant is presented as answering only from imported documents, naming the source page, and using Apple's on-device model; iCloud synchronization is described for Macs sharing an Apple Account.
