❓ Frequently Asked Questions
Is my compared text or source code saved on any remote server?
No. All text comparison algorithms, line-by-line diffing, and visual highlighting happen 100% locally inside your web browser. No text data ever leaves your device.
Does the tool support code comparison (HTML, JavaScript, CSS)?
Yes! The tool works with plain text, Markdown, legal contracts, HTML, CSS, JavaScript, and JSON snippets.
What is the difference between Side-by-Side and Inline view?
Side-by-Side view displays the original and modified texts in two separate parallel panels. Inline view merges both texts into a single stream, using green and red highlights for additions and deletions.
