Sift Text Diff

Spot every edit in seconds. Side-by-side and inline diff, word-level highlights, and a saved archive — all on device.

Sift is a fast, focused text diff tool for writers, editors, and developers.

Paste two versions of any text — drafts, code, contracts, emails, JSON — and Sift highlights every added, removed, and modified line in a clean side-by-side view. No accounts, no clutter, no upload to the cloud.

KEY FEATURES • Side-by-side diff with line numbers and clear rose/sage color coding • Inline diff view that shows +/- changes in a single column • Word-level highlighting on modified lines so subtle edits stand out • Ignore whitespace and ignore case toggles for noise-free comparisons • Save useful comparisons to the local archive and recall them in one tap • Quick swap between LEFT and RIGHT inputs • One-tap clipboard paste into either editor

BUILT FOR REAL WORK Whether you are reviewing a contract redline, checking a code refactor, comparing JSON payloads, or auditing a copy edit, Sift keeps the differences in front of you and the noise out of the way.

PRIVACY No accounts. No tracking. No network calls. All saved comparisons stay on your device.
