Mac
The native Mac diff for text, images, and folders. Now with intelligent, plain-English summaries, Live Mode, and a global launcher. One purchase, no subscription.
Mizan is the native Mac diff tool you've been waiting for.
Drop two files into Mizan and see exactly what changed, line by line, pixel by pixel, file by file. Built in Swift for Apple Silicon, designed for serious professional work, sold once. No subscription, ever.
WHAT YOU CAN COMPARE
Text:
Code, configs, contracts, drafts. 26+ languages with native syntax highlighting and word-level intra-line refinement.
Images:
Pixel-perfect difference detection. Side-by-side with synchronised zoom and pan, onion skin, difference overlay with auto-detected change bounding boxes, and swipe reveal.
Folders:
Recursive comparison with size, hash, or paranoid byte-by-byte matching. Tree and flat views. Filter by status or path.
Binary:
virtualised hex view that scrolls a megabyte at 60fps.
SIGNATURE FEATURES
INTELLIGENT DIFF SUMMARY:
Mizan reads your diff and writes a one-sentence plain-English summary above it. "Renamed `userId` to `accountId`, added 3 imports, and revised 6 lines." Detects renames, function additions, import changes, whitespace-only and comment-only diffs.
LIVE MODE:
Mizan watches your files. Edit either side in another app and the diff updates in real time, with a gentle pulse to confirm. Pair-program with Mizan watching over your shoulder.
CLIPBOARD DIFF:
Copy two snippets in a row and Mizan offers a one-click comparison. Privacy-first: opt-in, off by default, paused when Mizan isn't the active app, never sent anywhere.
PINBOARD:
Cmd-click any line to pin a note. Tag it Verify, Bug, Approved, or Question. Pins survive edits via context-based re-anchoring, when the file changes, the pin follows the closest matching line.
GLOBAL LAUNCHER:
Press ⌘⇧M from anywhere on your Mac to open Mizan's floating launcher. Compare your last two clipboard copies, reopen a recent pair, or drop in fresh files. One keystroke, zero windows.
FIND IN DIFF:
Search by case, regex, or by side. Matches highlight inline with the active match emphasised.
EXPORT:
Paginated PDF report with cover page, stat tiles, and color-coded hunks. Unified patch, JSON, Markdown, or self-contained HTML. Perfect for legal review, audit trails, or sharing with colleagues.
RECENT PAIRS:
Every comparison you've opened, searchable, pinnable, with at-a-glance natural-language change summaries.
THE WEIGHING:
Mizan's signature motion. When a diff first lands, the two panes settle into balance. Once per pair. Earned, not gratuitous.
BUILT FOR
Developers comparing branches, configs, and exported builds.
Lawyers and contract reviewers tracking revisions.
Auditors and compliance officers comparing spreadsheet versions.
Designers iterating on visual assets.
Technical writers tracking documentation.
Translators comparing source and target.
PRIVACY BY DESIGN
Mizan collects zero telemetry. No analytics, no crash reporting beyond Apple's built-in. Your files never leave your Mac. There is no account, no sign-in, no tracking. The Privacy Manifest declares this explicitly. The App Sandbox enforces it.
ONE PURCHASE
Mizan is sold once. You get the app, lifetime free updates for the 1.x series, and unlimited use across every Mac you own with the same Apple ID. No annual renewal, no feature tiers, no "Pro Plus."
REQUIREMENTS
macOS Sonoma or later. Apple Silicon native; Universal Binary supports Intel Macs.
