About Text Compare
Text Compare is a fast, privacy-first tool for identifying differences between two text blocks side by side. Whether you are reviewing code changes, comparing documents, or spotting edits, this tool highlights additions, deletions, and modifications instantly in your browser.
Perfect for developers, writers, and anyone who needs to verify changes without uploading sensitive data to external servers. All processing happens locally on your device, keeping your content completely private and secure.
How to use Text Compare
Paste Your Texts
Enter the original text in the left panel and the modified text in the right panel, or upload files to auto-fill.
Compare Automatically
The tool instantly analyzes both texts and displays all differences highlighted line-by-line in real time.
Review & Export
Review the color-coded changes, copy specific differences, or download the full comparison report as needed.
Pro Tips
- Use the 'Ignore Whitespace' option when comparing code or formatted text to focus only on content changes, not spacing differences.
- Check character-level diffs for subtle changes like punctuation, capitalization, or single-word substitutions that line-view might miss.
- Paste large documents directly into the tool-all processing happens locally, so size does not matter for privacy or speed.
- Export comparison results in unified diff format to share with team members or integrate with version control workflows.
