Frequently Asked Questions
What is a text diff tool and when should I use it?
A text diff tool compares two versions of text and highlights the differences β added, removed, or modified lines and words. It is essential for code reviews, document version comparison, contract analysis, and tracking changes between drafts.
How does the diff algorithm work?
Our Text Diff tool uses the Longest Common Subsequence (LCS) algorithm to find the optimal set of changes between two texts. It first splits the text into lines, then performs word-level comparison within changed lines to give precise, granular highlighting of what actually changed.
Is my text data safe when using this tool?
Absolutely. All text comparison runs entirely in your browser using client-side JavaScript. Your texts are never uploaded to any server, ensuring complete privacy for sensitive documents, source code, or confidential content.
