Text Tools
Compare two blocks of text side-by-side and highlight line-by-line differences, additions, and deletions with clear line numbers and unchanged context.
Follow these simple steps to get instant, accurate results directly in your browser:
Paste your baseline text into the original text pane.
Paste your updated text into the modified text pane.
Inspect the line-by-line diff showing exact additions, removals, similarity percentage, and line numbers.
The Text Compare tool compares two blocks of text side by side, highlighting additions, deletions, and unchanged lines with line numbers and accessible non-color indicators.
Using the longest common subsequence (LCS) dynamic programming algorithm, the tool computes the minimal edit script between original and modified text. Additions (+) are highlighted in green, deletions (−) in red, and identical lines are aligned with corresponding line numbers.
Comparison runs entirely in your browser memory, allowing confidential legal contracts, proprietary code snippets, and unreleased articles to be audited with privacy.
Calculates minimal difference paths for accurate line comparisons.
Includes +, −, and line number indicators so diffs are clear without relying solely on color.
Updates diff visualization instantaneously as you edit either pane.
All comparisons execute locally in browser memory with zero network uploads.
Spot subtle clause modifications, removed terms, and added clauses between legal drafts.
Identify unauthorized changes or regressions between code snippets.
Verify editorial corrections and track changes across article versions.
