How does the text diff tool work?

The tool compares two text inputs line by line. It identifies added lines (shown in green), removed lines (shown in red), and unchanged lines (shown normally). The comparison is done entirely in your browser for privacy and speed.

Can I compare files from my computer?

Yes, you can copy and paste text from any file into the text areas. The tool works with plain text, code files, documents, and any text-based content.

Is my text data secure and private?

Absolutely. All text comparison happens locally in your browser. Your text never leaves your device or gets sent to any servers, ensuring complete privacy and security.

What types of text can I compare?

You can compare any text content including code files, documents, configuration files, CSV data, log files, articles, emails, and any other text-based content.

Can I save or export the diff results?

Yes, you can copy the diff results to clipboard or download them as a text file. The output uses standard diff notation with + for additions, - for deletions, and spaces for unchanged lines.

Can I use this for code review?

Yes, this tool is excellent for basic code reviews. It shows line-by-line differences clearly. For more advanced code review features, consider dedicated development tools.
