Map a candidate master to likely crops, resizes, compressed copies, previews, thumbnails, and old renders using local evidence you can inspect.
Compare SHA-256 byte identity, media properties, dimensions, aspect ratio, duration, filenames, timestamps, on-device Vision feature prints, and deterministic crop-aware visual comparison. Visual evidence needs separate filename or folder context, and only identical hashes prove exact byte identity.
MasterKeep proposes a candidate master and possible derivatives. Every non-identical relationship stays probable, context-only, or unresolved until you review it.
Confirm a derivative, keep independent work, or leave the relationship unresolved. MasterKeep never turns similarity into an automatic file action.
Create a Base Report or a Pro Master Pack. Only user-confirmed derivatives may be left out; candidate masters, independent work, and unresolved files remain included.
Choose one project folder through Apple's Files picker, or open the clearly labeled Example Project.
Inspect each suggested file group and the facts connecting a candidate master to possible derivatives.
Confirm derivative, keep independent, or unresolved for every relationship. Your saved choice is authoritative.
Build a new Base Report or Master Pack without renaming, moving, overwriting, or deleting anything in the selected folder.
Hashes, media facts, Vision feature prints, deterministic crop-aware visual comparison, grouping, decisions, and export selection are processed on device. Visual evidence needs separate filename or folder context. There is no MasterKeep account, backend, cloud AI, advertising, analytics, or tracking. A File Provider may download a selected remote placeholder under that provider's behavior; MasterKeep does not upload it.
Free supports up to 40 files, the full review flow, and a Base Report ZIP with JSON, CSV, and a projected-size report. MasterKeep Pro Lifetime is one non-consumable purchase for up to 1,000 files, a reduced Master Pack ZIP with retained-asset copies, contact-sheet PDF, JSON, CSV, SHA256SUMS, size report, and local export history. There is no subscription.
USD 8.99 is the intended US reference price. Apple displays the current storefront price before confirmation. The paywall includes Restore Purchases, Privacy Policy, and Apple Standard EULA.

No. MasterKeep reads the folder and creates a separate export. It does not rename, move, overwrite, or delete selected source files, and it offers no source-delete action.
No. SHA-256 equality proves exact byte identity only. On-device Vision feature prints and deterministic crop-aware visual comparison are supporting evidence and require separate filename or folder context. They are not proof of creative history.
No. Deterministic local rules create evidence and labels. On eligible devices, Apple Intelligence may phrase those verified facts, but it cannot choose a master, change a relationship, select files, or perform a file action.
No. Folder analysis, Vision evidence, review, and export use no MasterKeep server. StoreKit needs App Store connectivity for purchase activity, and opening support or legal links uses the internet.
MasterKeep AI is designed for supported iPhone and iPad devices running iOS or iPadOS 18 or later. App Store availability and the current local purchase price are shown by Apple.
