Changelo answers one question: what changed? Instead of showing you a wall of technical diff, Changelo compares two versions of a file — or two whole folders — and explains the difference the way a person would: • "Only the photo's metadata changed — the image itself is untouched." • "One page was added and two paragraphs were edited." • "Probably a new build of the app: the version increased and two localizations were added." • "The data is identical — the file was merely re-saved." HOW IT WORKS Pick or drop two items, and in seconds you get a verdict in plain language, the reasons behind it, and a detailed list of changes. The visual, side-by-side diff is always one tap away — but only when you want it. UNDERSTANDS YOUR FILES Changelo doesn't compare bytes; it understands formats. A PDF is pages, paragraphs and annotations. A photo is pixels, EXIF and a color profile. A folder is a tree of files. An app is versions, frameworks and localizations. Supported today: plain text, JSON, plist, XML, YAML, CSV, Markdown, photos (JPEG, PNG, HEIC and more), PDF, folders, ZIP archives, SQLite databases, app bundles (.app, .ipa), disk images, and video metadata (QuickTime). SMART, NOT MAGIC Every answer comes from deterministic, verifiable analysis — no AI guessing. When a conclusion is heuristic, Changelo says so: verdicts are labeled Certain, Likely, or Possible. TRULY PRIVATE Changelo is 100% offline. No servers, no accounts, no analytics, no network access at all. Your files never leave your device. POWER FEATURES • Export a comparison as a Markdown or JSON report • Save results as .changelo documents and preview them with Quick Look • Add your own explanation rules • Deep-scan mode for very large files • Full localization into 15 languages
