About Text Compare
Introduction
The Text Compare tool is a side-by-side comparison utility designed to identify differences, additions, and deletions between two texts. Spotting changes between code blocks, legal contracts, drafts, or configuration parameters manually is difficult and error-prone.
This diff utility compares texts in real-time, highlighting matching and mismatched sections. It operates 100% locally in your browser, ensuring absolute security.
Key Features
Compare documents side-by-side or inline using these precise diff-checking controls:
- Side-by-Side View: Displays original and modified texts next to each other with color-coded highlights.
- Line and Word Diff: Identifies changes down to specific characters and words inside modified lines.
- Ignore Formatting Options: Choose to ignore case differences, trailing whitespace, or empty lines.
- Real-Time Analysis: Compare changes instantly as you edit the input panes.
How to Use
Find differences between two documents or code snippets by following these simple steps:
- Input Original Text: Paste your baseline draft or source code into the left "Original" panel.
- Input Modified Text: Paste the updated draft or code version into the right "Modified" panel.
- Review Highlights: Green highlights indicate additions, red indicates deletions, and yellow indicates modifications.
- Verify Differences: Adjust comparison settings (ignore case, spacing) to refine mismatch highlights.
Benefits
Writers can compare draft versions, developers can check code edits, and legal teams can verify contract additions. It is fast, lightweight, and works offline.
All comparison calculations are executed client-side, keeping your private legal drafts and proprietary code blocks secure.
