## What is Diff Checker?

Compare two versions of any text and see exactly what changed — line by line and word by word, highlighted the instant you paste.

Most "spot the difference" attempts end in squinting at two walls of text side by side. DiffCheck does the reading for you: paste an old version and a new one, and every addition turns green, every deletion turns red, so the change jumps out in a second. It works on code, config files, contracts, and plain prose alike — and it never sends a single character off your device.

WHAT YOU GET
- See every change at a glance — additions in green, deletions in red, nothing missed
- Switch between line-level and word-level diffs to catch even a single edited character
- Read changes in a clean side-by-side split view that lines the two versions up
- Copy a ready-to-use unified patch of any comparison straight to your clipboard
- Keep a local history of past comparisons so you can revisit what changed and when
- Save reusable snippets and sample diffs to compare the same text again fast

PERFECT FOR
- Developers reviewing code, pull requests, and config changes on the go
- Writers and editors checking edits between two drafts
- Legal and business users comparing contract or document revisions
- Students learning how diffs and the unified patch format work

WHY NOT JUST EYEBALL IT
Reading two versions by hand is where mistakes hide — a flipped number, a deleted clause, a changed flag. DiffCheck compares them character by character so you catch the change you would have scrolled right past.

PRIVACY
Your text never leaves your device. There are no accounts, no servers, and no tracking — every comparison happens fully offline.

FULL ACCESS
DiffCheck is free to compare text. Full Access unlocks word-level diffs, the side-by-side split view, saved comparison history, and unified patch export. Choose the plan that fits:
