MasterKeep AI
Trace creator file origins
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Map candidate masters to likely derivatives, confirm every relationship, and export a separate result while source files stay untouched.
MasterKeep AI helps photographers, designers, video editors, and other creators understand how files in one selected project folder may relate. It identifies a candidate master and likely crops, resizes, recompressed copies, previews, thumbnails, and old renders using inspectable local evidence. Relationships remain probable, context-only, or unresolved until you confirm them.
Choose a folder with Apple's Files picker. MasterKeep reads supported images, videos, and common creative-project files without changing them. It compares SHA-256 byte identity, media type, dimensions, aspect ratio, duration and bitrate clues, alpha and color-space clues, timestamps, filename clues, on-device Vision feature prints, and deterministic crop-aware visual comparison across multiple normalized-pixel anchors. Visual evidence requires separate filename or folder context before a relationship can be suggested. Proprietary creative formats stay opaque. Video evidence uses representative frames, not codec I-frames.
Review each candidate master → derivative group. For every candidate, confirm derivative, keep as independent work, or leave unresolved. Only user-confirmed derivatives may be omitted from a new Master Pack. Candidate masters, independent work, and unresolved files are always retained. MasterKeep never renames, moves, overwrites, or deletes source files.
Free audits support up to 40 supported files and can export a Base Report ZIP with JSON, CSV, and a projected-size report. MasterKeep Pro Lifetime is one non-consumable in-app purchase that supports up to 1,000 files and adds a reduced Master Pack ZIP with retained-asset copies, a contact-sheet PDF, JSON, CSV, SHA256SUMS, size report, and local export history. USD 8.99 is the intended US reference price; Apple shows the current local price before purchase. There is no subscription.
Analysis and decisions run on device. MasterKeep has no account, backend, cloud AI, ads, analytics, or tracking. On eligible iOS 26 devices, Apple Intelligence may optionally phrase already-verified facts; it never chooses a master, changes a relationship, selects files, or performs file actions. Deterministic local wording remains available on iOS 18.
