The tool uses a word-based diff algorithm that breaks down both texts into individual words and tokens, then calculates the shortest edit distance to identify what was added, removed, or changed.

Yes, all processing is performed locally in your browser. Your text is never uploaded to a server, ensuring total privacy for sensitive documents.

While it focuses on word-level differences for precision, you can clearly see line changes as the algorithm tracks the position of words across the entire document.

Yes, by default the comparison is case-sensitive, meaning 'Apple' and 'apple' will be highlighted as a difference. This is crucial for code and technical writing.

Absolutely! The tool works well for comparing functions, CSS styles, or configuration files. However, it doesn't provide language-specific syntax highlighting.

Green highlighting indicates text that exists in the 'Modified' version but not the 'Original' (Additions). Red highlighting (often with strikethrough) indicates text that exists in the 'Original' but was removed in the 'Modified' version (Deletions).

Yes, it can compare thousands of words. However, extremely large files (like whole books) might cause a brief pause while the browser calculates the differences.

If a paragraph is moved, the tool will show it as a deletion in the old location and an addition in the new one. This makes it easy to track structural changes.

Yes, punctuation marks are treated as separate tokens, so added or removed commas, periods, or quotes will be highlighted clearly.

Currently, you can view the results on-screen. To save them, you can take a screenshot or copy the highlighted text into a supporting editor.
