ShelfKeeper — NAS Butler keeps a UGREEN NAS library tidy and answerable: it deduplicates and organizes messy folders, answers natural-language questions about stored files with verified paths, and writes a weekly housekeeping digest.
Home and small-office NAS owners' drives become write-only dumps: phone backups, downloads, and documents land unsorted, duplicates waste space, and finding one file months later means manually digging through thousands of items.
ShelfKeeper maintains a Library Ledger: a plain Markdown catalog of the library, stored on the NAS itself. Each tidy run updates it; each question is answered from it and verified live; each week it produces a digest of arrivals, waiting duplicates, and stale content.
The user names a folder; ShelfKeeper inventories it, shows duplicate groups and a complete move plan, and only after confirmation organizes, tags, and updates the ledger. Later, the user asks questions in plain language and receives exact paths, or a clear 'not found.'
Generic AI assistants answer from filenames or guess; cloud organizers require uploading private files. ShelfKeeper answers from a persistent, human-readable catalog on the user's own device, verifies every path before answering, and never moves anything without confirmation.
It uses UGREEN AI NAS features — Files (inventory, deduplication, moving, tagging; live path verification), Albums (grouping photos by person, place, and time), Documents (extracting summaries, dates, and parties so documents are filed and found by content), and Knowledge (saving the ledger and weekly digests) — in three modes: Tidy, Find, Digest. Permissions are read-first with mandatory confirmation before any move or deletion, and processing stays local on the device.
