What is a Text Diff Checker?
A diff answers “what changed?” between two versions of anything: configs, contracts, exported data, code snippets, far faster and more reliably than eyeballing.
This tool computes a longest-common-subsequence line diff locally: unchanged lines stay plain, removals show in red with −, additions in green with +.
Frequently asked questions
Is the comparison by line or by character?
By line: the right granularity for configs, lists and prose paragraphs.
A line moved: how does that show?
A move appears as a removal at the old place and an addition at the new one; the diff doesn’t track identity.
Trailing spaces make lines “differ”: why?
Lines must match exactly. Run both texts through the Whitespace Cleaner first to ignore spacing noise.
Are my texts uploaded?
No: comparison is local, safe for contracts and configs.
